The Heart Nebula
The Heart Nebula is about 7500 light-years from Earth in the Perseus Arm of the Milky Way. This emission nebula is a hot gas and dark dust lane. The nebula is composed of plasma dominated by hydrogen ions and free electrons. At the center of the heart, One is about 1.5 million years old.
By Jeremy Likness who said that the 336mm focal length (sv503 70ED w/ 0.8x field reducer) was perfect for it. One frame which is where most of the clear stars came from was with the Svbony IR/UV cut filter!

Pacman Nebula in Hubble Palette
This is a depiction of the Pacman Nebula (NGC 281) in a color palette commonly known as the Hubble Palette.
The data was captured using three narrowband filters; Hydrogen-Alpha (Ha), Oxygen III (O3) and Sulfur II (S2) emission lines.
Final image is a blend of these three narrowband images assigned as S2 to the Red channel, Ha+S2 to the Green channel and O3 to the Blue channel.
1) Equipment used:
Camera : ZWO ASI1600MM - monochrome camera Filter and Wheel : Baader 36mm unmounted filters with ZWO Electronic Filter Wheel Telescope : TS Optics TS107/700 with 0.8x focal reducer (effective focal length 560 mm f/5.2) Mount : Skywatcher EQ6-R Pro with EQMOD control software with Stellarium. Guiding : Astromanis 60mm with ZWO ASI-120MM-S monochrome camera Capturing Software : Sequence Generator Pro
Captured 50x360 secs of Ha. 50x300 secs of O3. 50x480 secs of S2.
30xflats in each channel 30xdarks in each channel
Bortle sky scale is on border of 5-6. ​
2) Pre-processing Using PixInsight (PI):
Use this tutorial as the guide and I change the workflow a bit depending on the target:
http://www.lightvortexastronomy.com/tutorial-pre-processing-calibrating-and-stacking-images-in-pixinsight.html
PI processes used for pre-processing: ImageCalibration, CosmeticCorrection, SubframeSelector (script), StarAlignment, LocalNormalization, ImageIntegration and DrizzleIntegration
​ 3) PI processes used for integration:
Started with DynamicCrop and basic Dynamic Background Extraction in each channel. Linear fit the O3 and Ha to S2. Channel Combination with PixelMath. Red - S2, Green - Ha, Blue - O3. Background Neutralization. Color Calibration. Extracted star mask and used Morphological Transformation for star reduction. Extracted lightness mask and used with Multiscale Linear Transformation in Luminance first and then on Chrominance. ACDNR for low scale noise reduction. Histogram transformation with Arcsinhstretch. Used the masks for two sets of curves transformation, once for star color and once for overall. Hue transformation for the golden/blue tone. SCNR with green reduction. Curves transformation for added saturation.

First shot of the season in the constellation Orion! The 1000+ focal length did get me wonderfully close to the Horsehead Nebula (B33) in the constellation Orion. This is what 46 stacked 600 second hydrogen-alpha frames will get you if you stretch things a bit too much and don't use any calibration frames. That would reduce the noise/graininess somewhat. Anyway, pretty happy with this.
I set up the AstroTech RC scope (6"/152mm aperture f/9) with my narrowband imaging train, Atik 414EX, ZWO filter wheel with Clear, Ha, OIII, SII & IR685, William Optics 0.8x field flattener/reducer that brings the AT6RC to f/7.2 at 1080mm focal length.  With the Atik's 6.45μ pixels, this has my resolution at 1.23 arcseconds per pixel, and a field of view of .48° x .36°.
I took some shots of my astro imaging set up last night--before nightfall, and in the middle of the narrowband run with 40 600-second exposures. https://SaltwaterWitch.com

M101_April2017_HomCavObservatory by homcavobservatory Via Flickr: M101 is a face-on, grand design spiral galaxy lying approximately 21 million light-years from Earth. Containing the equivilant of 1 trillion solar masses, it spans about 170,000 light-years from edge-to-edge. Fairly large, it appears over 28 arcminutes in diameter in our sky (i.e. approximately the size of the full moon), and can be found in the constellation of Ursa Major. Often referred to as the Pinwheel galaxy, it shares that moniker with the galaxy M33 in Triangulum. The attached image is via our wide-field imaging system and covers over 3 degrees (i.e. 6 full moons) in width, with North at left. Several other smaller and fainter galaxies can found near M101's; to it's lower right is the round galaxy NGC 5474, to it's upper left the edge-on spiral galaxy NGC 5422 and to it's lower left and just discernible in this image are NGC 5473, 5485 & 5486. Taken by Jay Edwards at the HomCav Observatory in Maine, NY while out shooting the most recent comets on the morning of April 19th using an Orion ED80T CF Triplet Apochromatic Refractor connected to a 0.8x Televue field flattener & focal reducer, CamRanger, IPad and Canon 700D DSLR; and guided by an Orion StarShoot autoguider connected to a Celestron 80MM short tube refractor; all riding on an Orion SkyView Pro goto mount guided by PHD, this image is nearly full frame and has been resized down here to HD resolution and the bit depth lowered from 16 to 8 bits per channel to reduce the file size.

Nikon Unveils the Z Series Full-Frame Mirrorless Camera System
After months and months of hints, rumors, leaks, speculations, and teasers, Nikon just finally officially unveiled the highly-anticipated Z Series, its first full-frame mirrorless camera system.
Nikon is launching the Z Series with two cameras, three lenses, and one lens adapter.
The New Z Lens Mount
“We have been refining our optical technologies for over 100 years,” Nikon stated at its global launch event. The Z Series features a brand new lens mount that’s designed to “redefine possibilities” and elevate optical performance for Nikon over the coming decades.
“This is the new light that Nikon will use to pioneer the future,” Nikon says. “It is indeed mirrorless reinvented.”
The Z mount uses a large 55mm inner diameter and a 16mm flange focal distance that allow for apertures as fast as f/0.95. It also opens the door to other lens properties that weren’t previously possible with Nikon’s F mount.
F-mount lenses will be fully compatible with Z mount cameras using the new FTZ Mount Lens Adapter.
Nikon says the new lens mount will also allow its Z mount to be future proof, allowing for cameras with higher and higher resolutions and optics with greater and greater sharpness.
Nikon Z7: A Flagship High-Res Mirrorless Camera
The new Nikon Z7 is Nikon’s flagship full-frame mirrorless camera, featuring high-resolution photography and “revolutionary” autofocus.
The camera features a 45.7-megapixel backside-illuminated full-frame CMOS sensor with a native ISO of 64-25,600. It has an EXPEED 6 image processor that supports 9fps continuous shooting.
The Z7 packs a groundbreaking autofocus system that boasts a whopping 493 AF points that cover 90% of the viewfinder area.
Nikon Z6: A High-Speed, Low-Light Powerhouse
The new Nikon Z6 is designed to be an all-around, high-speed, low-light camera. It features a backside-illuminated 24.5-megapixel full-frame sensor with a native ISO range of 100-51200. Backed by an EXPEED 6 image processor, the Z6 can do 12fps continuous shooting.
There’s a 273-point on-sensor phase-detect autofocus system.
Z7 and Z6 Shared Features
Aside from the handful of ways in which the Z6 and Z7 differ, the two cameras are identical in physical design and share their other features and specs.
Both cameras feature durable, dust- and drip-resistant builds and a large, firm grip for secure and comfortable holding.
On the top of the cameras is a relatively large information display, two dials, a dedicated video recording button, an ISO selection button, and an exposure compensation button next to the shutter button.
The electronic viewfinder features a resolution of 3.69 million dots and provides an edge-to-edge clear, natural view with minimal aberrations. It has a frame coverage of approximately 100%, a magnification of 0.8x, and a 37-degree diagonal viewing angle. On the EVF is a fluorine coating that repels dirt.
While looking through the EVF, photographers can pull up the i menu to see and adjust shooting settings such as ISO, AF-area mode, and Picture Control.
Under the EVF is a 3.2-inch, 2.1-million-dot touchscreen tiltable LCD.
Both cameras feature a hybrid AF system that uses an algorithm to automatically switch between focal-plane phase-detection AF and contrast-detect AF.
For the first time, in-camera 5-axis vibration reduction is appearing in a Nikon camera. The system provides 5-stops of compensation and is also compatible with F-mount lenses mounted to the lens adapter.
On the video front, both cameras can shoot 4K Ultra HD footage. Other video features include 10-bit N-Log HDMI output, Active D-Lighting, electronic vibration reduction, focus peaking, timecode sync support, and 120fps slow-motion recording at 1080 resolution.
Nikon says it’s developing an MB-N10 Multi-Power Battery Pack that will provide long hours of shooting. It will increase the number of photos possible and the maximum recording time by 1.8x.
The bottom of the Z7 and Z6 features a standard tripod mount and the battery compartment door.
Both cameras are compatible with existing Nikon DSLR accessories such as EN-EL15/a/b batteries, WT-7/A/B/C Wireless Transmitter, and radio/optical Advanced Wireless Lighting.
Other features found in both cameras include a silent photography feature (for shooting with zero shake and noise), 20 Creative Picture Control options (with adjustable effect levels from 0 to 100), an intervalometer for shooting time-lapses, and built-in Wi-Fi.
Nikkor Z Lenses
Nikon has announced three initial Nikkor Z lenses: the 24-70mm f/4 S, 35mm f/1.8 S, and 50mm f/1.8 S.
The new S-Line of Nikon lenses are products that feature Nano Crystal Coating and have met a more rigorous standard of quality than ever before. The lenses are fully sealed — even the moving parts — and are resistant to both dust and drips.
Each control ring on the new lenses provides quieter and smoother aperture and focus changes — ideal for professional video recording. The lenses also feature reduced focus breathing and have a quieter AF drive.
Nikkor Z 24-70mm f/4 S Lens
The new Nikkor Z 24-70mm f/4 S is designed to “change the perception of what is possible with zoom lenses with a maximum aperture of f/4,” Nikon says.
Features and specs include a minimum focusing distance of just 0.3m (~0.98ft), a retracting mechanism that can be set on/off without pressing a button, and a fluorine coating.
Nikkor Z 35mm f/1.8 S Lens
The new 35mm f/1.8 features a new multi-focusing system with two AF drive units for high-speed, high-accuracy, low-noise performance.
Nikkor Z 50mm f/1.8 S Lens
The new 50mm f/1.8 provides soft and beautiful bokeh and features a new powerful stepping motor (STM) for quiet and accurate AF control for both photo shooting and video recording.
Nikkor Z 58mm f/0.95 S NOCT Lens
Nikon has announced that it’s developing a 58mm f/0.95 lens for its Z Series. The manual focus lens will be the fastest lens ever created in Nikon’s history.
“It will stand to symbolize the Nikon Z mount system’s new dimension in optical performance,” Nikon says. “It has inherited the design concept behind the original AI Noct-NIKKOR 58mm f/1.2, a standard prime lens released in 1977, named for ‘Nocturne’ (a musical composition inspired by or evocative of the night), and was popular for its ability to finely reproduce point light sources as point images.
“This new Noct lens that is currently in development will take advantage of the advanced design flexibility afforded by the Z mount, pursuing ultimate optical performance.”
Lens Roadmap
Nikon has revealed its lens roadmap for the Z Series over the next few years. After the three lenses launching this year, Nikon is planning to release six lenses in 2019: the 58mm f/0.95, a 20mm f/1.8, an 85mm f/1.8, a 24-70mm f/2.8, a 70-200mm f/2.8, and a 14-30mm f/4. Then there are three lenses scheduled for 2020: a 50mm f/1.2, a 24mm f/1.8, and a 14-24mm f/2.8.
Nikon FTZ Lens Adapter
The new lightweight Nikon FTZ lens adapter provides compatibility for about 360 existing F-mount lenses from AI type onwards.
Lenses without VR will automatically be stabilized by the Z Series’ cameras in-body stabilization (3-axis). Lenses with VR will have their VR systems work together with the in-camera VR.
Like the lenses, the Nikon FTZ is sealed from dust and drips.
Pricing and Availability
The Nikon Z7 and Z6 are designed to go toe-to-toe with high-end DSLRs, and they both have price tags that reflect that. The Z7 will be available on September 27th with a price tag of $3,400. The Z6 will hit stores in late November with a price tag of $1,996. When paired with the new 24-70mm lens, the Z7 and the Z6 will cost $4,000 and $2,600, respectively.
The Nikkor Z 24-70mm f/4 S and 35mm f/1.8 S will be available on September 27th and will cost $1,000 and $850, respectively. The 50mm f/1.8 S will be available in late October with a price tag of $600.
The Nikon FTZ Mount Adapter will be available on September 27th with a price tag of $250.

Туманность Лагуна, М 8
http://popular-astronomy.ru
Туманность Лагуна (англ. Messier 8, NGC 6523, M 8, рус. Мессье 8) - гигантское межзвёздное облако и область H 2 в созвездии Стрельца. Находясь на расстоянии 5200 световых лет, туманность Лагуна одна из двух звёздоформир��ющих туманностей слабо различимых невооружённым глазом в средних широтах Северного полушария. При рассмотрении в бинокль, Лагуна представляется чётко очерченным овальным облакоподобным пятном с явным ядром, похожим на бледный звёздный цветок. Туманность содержит небольшое звёздное скопление, наложенное на неё, что превращает Лагуну в одну из достопримечательностей летнего ночного неба.

About this product
Product Information The compact 10.2-MP D60 delivers breathtaking picture quality and the versatile handling of a D-SLR, yet is incredibly compact, easy and fun to use.Nikon’s high-performance, 10.2-megapixel DX-format CCD imaging sensor and exclusive EXPEED image processing concept provide added cropping freedom and the ability to make larger prints.With fast startup and split-second shutter response, the D60 eliminates the frustration of shutter delay, capturing moments that other cameras miss.Capture sports action, precious moments and fleeting expressions at up to 3 frames per second, for as many as 100 consecutive JPEG images.Nikon’s Active Dust Reduction System activates automatically, along with Airflow Control technology to reduce the amount of dust that reaches the sensor.Intuitive controls and an onboard HELP Menu System with Assist Images make the D60 truly easy to use, enabling everyone to capture beautiful memories perfectly.Nikon’s original digital image processing concept, EXPEED, comprehensively optimizes pictures, shot after shot.Beautifully styled, the D60 makes high-performance digital SLR photography easier and more convenient than ever. You’ll be amazed at the power packed into a camera that weighs just over 16 ounces.Playback images are easy to see and function menus are easier to use with a larger and brighter color LCD monitor. The large 2.5-inch LCD monitor enables image preview at up to 19 times magnification and has large type fonts with easy-to-view menus. Auto rotating LCD display provides automatic horizontal and vertical graphic display orientation.The D60’s Assist Images help you select the appropriate settings for many camera features by showing an example image typical of that setting, as well as an advanced HELP Menu for the current item selected. The D60’s Question Mark icon (?) indicates that help is available for the currently selected item; just press the HELP button beside the LCD monitor to see a context-sensitive HELP page.The D60’s 3D Color Matrix Metering II evaluates each scene for brightness, color, contrast, size and position of shadows and highlights, selected focus area and camera-to-subject distance, comparing that information against an onboard database of more than 30,000 actual photographic scenes. The result delivers instantly and precisely determined exposures for each scene, even in challenging lighting conditions.The D60’s Optimize Image setting lets photographers adjust color, contrast and sharpening, as well as other image settings, according to the type of scene or output desired. Settings include: Normal, Softer, Vivid, More Vivid, Portrait, Custom and Black and White, each of which are automatically adjusted based on sophisticated Nikon algorithms or user-selected settings for optimum results.Nikon’s innovative i-TTL flash control evaluates flash exposure with incredible precision to achieve better automatic flash balance and deliver outstanding results. The built-in Speedlight is always readyto bring beautiful exposuresto darkened conditions, as well as add sparkle for fill flash in outdoor situations for enhanced twilight shots or an added impact to daylight images. In low-light or back-light situations, added illumination from the built-in Speedlight can make the difference between an average snapshot and a dazzling picture.The D60’s advanced 3-Area AF system and the refined algorithms inherited from more advanced Nikon digital SLR cameras deliver fast, efficient and precise Autofocus. AF refinements deliver greater precision with fast, more consistent subject acquisition and improved focus tracking for consistently sharper pictures.
