Finally got a chance to image the winter zodiacal light for this year. I've made the post-processing more subtle.
This was a challenge for the small Esprit 100mm f5.5 APO refractor with Optolong L filter and Canon 6D. A combination of full spectrum 16x300sec iso1600 and 12nm Halpha 30x600sec iso1600. Both stacked in DeepSkyStacker using 3x drizzle (+25 Flats and 65Bias) and combined in Pixinsight with the NBRGB Combination script. Image dates: 21 november 2015 for Ha and 5 december 2015 for RGB.

Frames registered and stacked in DeepSkyStacker software; curves adjusted in Canon Photo Professional; noise reduction in CyberLink PhotoDirector.
My first session with the 12" Newtonian since May, and unfortunately not very successful due to the aberrations (coma and tllt) that distort the stars (I've cropped the worst of it out). It seems to be worst when I image objects high in the sky, while those closer to the horizon have better-shaped stars.

When considering there was a full moon last night 26-4-2021, I am both supprised and pleased I managed to capture the Whirlpool Galaxy.
39 lights, 10@2min 10@3mins 9@4mins, 9darks, stacked in DeepskyStacker, post processed in Photoshop.
Nikon D750, Nikon 600mm prime with Nikon 2xteleconverter (1200mm) on a Skywatcher NEQ6-R-Pro mount, polmaster, Stellarium, PHD2 guide, DSLR control WiFi capture, bortle4.
The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy.
The Crescent Nebula (NGC 6888) is an emission nebula formed by a strong stellar wind from an extremely hot Wolf-Rayet star as it collides into and excites material that had been previously ejected from the star during it's red giant phase. Located approximately 5,000 light-years from Earth, the shell has a diameter of about 25 light-years in diameter.
Glowing at magnitude 7.4 in the constellation of Cygnus, although visible in smaller instruments, in large scopes under dark skies it appears as a fractured globe. Having had the pleasure of viewing this object in my friend's 20-inch, f/5 Obsession from the dark skies of the high desserts on the Snake River Plain in Idaho, it took on an incredible 3-D appearance (as one of my friends noted, looking like a partially constructed 'Death Star' from Star Wars :) ).
Image Details: The attached was taken by Jay Edwards at the HomCav Observatory on the evening of July 27, 2019 using an 8-inch, f/7 Criterion newtonian reflector and a Canon 700D DSLR tracked on a Losmandy G-11 mount running a Gemini 2 control system. This in turn was guided using PHD2 to control a ZWO ASI290MC planetary camera / auto-guider in an 80mm f/6 Celestron 'short-tube' refractor.
Shot at ISO 1600, it is a stack of 75 one-minute exposures (not including darks, flats & bias frames). Given the reasonable results I'm looking forward to trying this object sometime in the future using the same scope with one of our CCD and sets of narrowband filters in an attempt to pick up additional detail of the nebula's interior structure.
Stacked in DeepSkyStacker and processed using PixInsight and PaintShopPro, as presented here it has been cropped slightly, re-sized down to HD resolution and the bit depth has been lowered to 8 bits per channel.
The above was created from the series of images in this star trail shot: www.flickr.com/photos/steventheamusing/11240440045/
For fun I took the shots used in my "Life is a Beach Sometimes" shot (posted earlier), and masked off the foreground. I then ran them through DeepSkyStacker which is normally used for astroimaging. DSS wouldn't know what to do with the land.
There is a strong gradient left that I didn't remove... it's due to the light pollution from the nearby buildings and streetlights together with the mist and fog.
These shots were all ISO 1600, f/2.8, 20 seconds (which was too long for this purpose since it cause stars to be streaks rather than points of light).

Unfortunately the first evening with a chance to image this comet coincided with the brightest Full Moon of the year, so some subtle details are no doubt lost! Nevertheless, the comet’s ‘anti-tail’ can just be seen pointing towards the 5 o’clock position.

Orion Nebula in Orion - M42. 8 December 2010
Same old subject - sorry guys. Took this for a reason though - first light for my diy modded Nikon D70 (removed the infra red filter in front of the sensor). This makes the camera more sensitive to the wavelengths we want in astro images.

Test image after the Bayer matrix was scraped from the sensor. Cooling will be needed, of course.
It looks like there's blooming on 62Cyg, the brightest star. I'm not sure what happened there. I would not expect blooming from a DSLR, but perhaps scraping the sensor damaged something?

This is something I've always wanted to do with a halfway decent camera and some software. Unfortunately, not near the city lights like I did here.
The image is a composite of 10 consecutive shots. A great freeware program called DeepSkyStacker was used to line up the stars, stack the images and filter out any anomalous sensor data from the camera.
The foreground portion with the farm field was masked-in using photoshop from a single image as the composite blurred this portion due to the earth's movement. You can still see the blur in the silhouette of the trees however. I thought this added a nice touch to the finished product though.
Next, I will try to do this away from city lights now that I understand the process a little better.

Cederblad 214, also known as Sh2-171, is an extensive emission nebula which is linked to Cepheus OB4 and is illuminated by the stars of the open cluster Berkeley 59. Vigorous star-formation processes are taking place inside it generating low-mass stars.
The nebulosity spans about 40 light years across and is located some 3000 light years away.
Within Cederblad 214 lies one of the hottest known stars (actually a binary system) designated as BD+66 1673. Its surface temperature approaches 45000K while its luminosity is about 100000 times that of the Sun.

In the Sharpless catalogue as SH2-206. Sometimes called the Fossil Footprint Nebula.
This is an emission nebula just under 11,000 light years away in the constellation of Perseus.
HII regions of space such as this are formed when the ultraviolet radiation generated by hot stars ionizes the surrounding gas, causing it to glow in the visible light.
You often hear tell that stars are made from dust & gas, well the dust is also affected by this radiation too. The radiation makes the dust glow in the infrared light.
Boring techie bit.

I was testing the ED80 with a full-frame sensor. I think the result is pretty good, but with significant aberrations (coma?) in the corners. Please let me know if you have advice for correcting the coma. Eg, do I need more space between the reducer and the sensor, or less space?

- www.kevin-palmer.com - The Lagoon and Trifid Nebulas are located in Sagittarius, one of the most interesting parts of the sky. On the upper left is the very dense Sagittarius Star Cloud, and another dimmer nebula below it. This is a stack of 13 2-minute, iso 1600 exposures with a Takumar 135mm f2.5 lens. An iOptron Skytracker was used to track the stars. This was taken at Sand Ridge State Forest, which has moderately dark skies.
Finally got something that sure looks like a galaxy compared to my last post about 4 years ago trying to figure out if it was indeed M31 in the image DSS spit out.
Such a massive Galaxy coming head on at us in the Milkyway in what will be a collision of stellar magnitude in a few billion years.

Celestron 1100HD on CGEM DX. QSI 640 with Maxim LE. Six each of RGB at 5 minutes and 2x2 bin. Nine luminance at 10 minutes and 1x1 bin. Used DeepSkyStacker to stack the four sets separately and then used GIMP to combine the R, G and B images into single shot. Then converted RGB -> YUV and replaced Y with luminance shot, finally converting back to RGB.
Love the new camera - even with relatively few subs I get the Cocoon with almost no noise!
