Helix Nebula
The Helix Nebula, also known as The Helix, NGC 7293, is a large planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae.[5] The estimated distance is about 215 parsecs (700 light-years). It is similar in appearance to the Cat's Eye Nebula and the Ring Nebula, whose size, age, and physical characteristics are similar to the Dumbbell Nebula, varying only in its relative proximity and the appearance from the equatorial viewing angle.[6] The Helix Nebula has sometimes been referred to as the "Eye of God" in pop culture,[7] as well as the "Eye of Sauron".[8][9]

NGC 4449, also known as Caldwell 21, is an irregular Magellanic type galaxy in the constellation Canes Venatici, being located about 13 million light-years away. It is part of the M94 Group or Canes Venatici I Group that is relatively close to the Local Group hosting our Milky Way galaxy. This galaxy is similar in nature to the Milky Way's satellite galaxy, the Large Magellanic Cloud (LMC), though it is not as bright nor as large. NGC 4449 has a general bar shape, also characteristic of the LMC, with scattered young blue star clusters.

Here is my latest Cocoon Nebula - this time using the ZWO ASI294MC Pro in place of the DSLR.
The IDAS NGS1 (Night Glow Suppression) Filter did a great job of blocking much of the white LED street lamp glow that surrounds my little house.

Stacking - DeepSkyStacker.
Edition in PS.
An unspectacular view of the comet between the trees at the bottom of our garden, just before midnight on 17/18 July.
This is a revised stack of six images in DeepSkyStacker, colour-corrected to remove the orange glow of tungsten lighting. Stacking followed the tutorial by Dave Eagle at www.skyatnightmagazine.com/astrophotography/astrophoto-ti....
The software looks impressive and is free to use. Unfortunately it depends on a library to work with RAW files that has not yet been updated to include the camera I used here ... so I worked with 4k res JPG files.
I know I've not long since imaged this but, I'd setup in hope of the clouds clearing over my local observatory.
Just as I was about to pack everything away, we got a gap in the clouds. M27 was ideally placed right in the gap, so I managed to get 30 exposures of 2 minutes each and some calibration frames with them.

This is the galaxy designated NGC 3206 in the constellation Ursa Major. The galaxy currently has a supernova designated as SN 2024bch. It was discovered on January 29, 2024 by Patrick Wiggins from the University of Utah (USA). During my 60-minutes of collected data, SN 2024bch showed a magnitude of 14.7, dimming from its peak magnitude in early February 2024.

lots and lots of cleanup in photoshop CS - to fix internal reflections and ccd bleed.
final tweaks and color balance in lightroom 2
comments: color subexposures were way too long, resulting in a ridiculous amount of star halo and ccd bleed on the 3 largest stars. this took a lot of work in photoshop to undo, and it's still obvious that there was a big problem there. this was especially bad in the blue channel, hence the purple cast around the big stars.

A few things came together for this one...
After a lot of experimenting, I can say I'm finally happy with some of the results. And aside from all the technique, it took me quite a bit of patience to catch a long exposure with a truck on the road making colorful light trails in front of mountainous scenery without getting the shot ruined with oncoming headlights. Then up top, I got the stars including Rigel and a few constellations to appear as points of light. Best of all, it looks good large!
This image, coming from several exposures taken in sequence, was captured on Loveland Pass, near the Arapahoe Basin Ski Area and Keystone, Colorado. Oh and those glowing clouds at the top of the mountains... That glow comes all the way from Denver - some 50 miles away!
On the tech side, I used Deep Sky Stacker to reduce noise in the stars by combining 10 8 second exposures (ISO 3200, f/3.2). Then I used a homemade approach to extrapolate the settings needed for a long exposure of the foreground. It allowed me to test in 8 seconds and shoot something cool in 8 minutes (ISO 200, f/4)... sweet!! Oh yea, and I figured out how to (finally) use my live view in the dark for precision focus. On that I'll have to say when I first saw this mostly focused 8 minute exposure taken at ISO 200, I smiled really wide! So after combining the short frames in Deep Sky Stacker, I just blended the results with the foreground in PS.

I took some time to collect some additional data on the galaxies Messier 81 and Messier 82 (M81 and M82) in the constellation Ursa Major on the evening of February 28, 2016. I used my wide-field setup which includes my Canon 6D and Canon 400mm lens mounted on an iOptron ZEQ25 mount. I collected 28-minutes of data using 60-second sub frames at ISO 3200. I also took the time to clip and process some of the background galaxies in my large 3 x 5 degree image, you can view them on my blog at: www.leisurelyscientist.com/?p=1592
Among the astrophotographs I made, this is, at the moment, the one with the longest total exposure time, totaling 19 hours and 35 minutes (captured in four nights).

A photo of the Andromeda Galaxy (M 31, NGC 224) captured in my backyard with a 200mm lens. The small elliptic Galaxy M 110 accompanying M 31, as well as M 32 is also visible in the photo. The distance of the Andromeda Galaxy is about 2,5 million light-years. What sounds like yet another dry scientific fact, actually means that the light captured by the camera CCD started its journey about 2,5 Million years before some clever guy invented DSLR cameras.
Actually, this photo is the result of an experiment which started as an crazy idea some weeks ago when I got hold of an old RET 45 4.5" Newton Reflector.
The photo has been stacked together from 44 individual 29 Second exposures, which results in an effective total exposure time of about 21 Minutes. Stacking has been performed with DeepSkyStacker (DSS). For post processing, Fitswork and AfterShotPro has been used.
To avoid star trails, I retrofitted the EQ2 mount of the RET 45 with a crystal controlled stepper motor, and replaced the counterweight bar by a self-made camera mount. In this way, the camera is used as counterweight of the mount which sufficient to track the camera for about 30 Seconds.

Downloaded the trial version of PixInsight the other day (for the third time), and gave it a good going over, as much as I could. Finally came to the conclusion, rightly or wrongly, that there isn't a huge amount in PI that can't be done in PS, with one or two exceptions, one of which is DBE.
I used DBE on this as the gradient had caused problems in my previous iterations, then processed in PS. One other plus from PI was that, having studied a few tutorials, I learnt a bit more about noise reduction, and put that into practice.
This has to be my final version of this - I'm not going to get anything more out of it. I think it beats my previous one :) I saw a version of this the other day, probably better than this, that consisted of less than 3 hours of 5 minute subs - my skies got a verbal lashing that night, I can tell ya! :)

The Whirlpool Galaxy, with it's companion galaxy NGC 5195, is an interacting grand-design spiral galaxy with an active galactic nucleus. It is located in the constellation Canes Venatici. It was the first galaxy to be classified as a spiral galaxy. The gravitational interactions between the two galaxies have distorted the spiral arms of Messier 51 and triggered bursts of star formation. Faint clouds and streamers of stars that have been disturbed from their orbits can be seen in the space surrounding the two galaxies.

16 x 30-sec exposures at f/4.5 and ISO 3200 with an EOS 600D and Zeiss Jena 135mm f/3.5 lens on a Vixen Polarie star tracker. The frames were stacked on the comet in DeepSkyStacker, with curves adjustment and further noise reduction in post-processing. The image was also heavily cropped.
NGC 891 is an edge-on barred spiral galaxy in the constellation Andromeda, located about 30 million light years from Earth.
This was imaged using a combination of cameras and telescopes. I imaged the luminance with the QSI 683 wsg-8 and the color data was imaged with a modified Canon T1i in 2011.
Imaged from Ocala, FL
Combination of 240 sec. and 360 sec. exposure stacked in DeepSkyStacker for a total of 5 hours and 23 minutes in the RGB channel
6 minute exposures stacked in DeepSkyStacker totaling 3.6 hours in the luminance channel.
Processed in Photoshop CS5

Losmandy G 11 with Gemini II
The Perseus molecular cloud complex, about 1,000 light-years from Earth, contains two notable areas of star formation: the IC 348 star cluster on the lower left, and NGC 1333 (VdB 17) on the upper right. Other DSOs in this extent include: Barnards 1,3,5, 202, 204, 203, 205, 206; and reflection nebulae VdB 12 (yellow), VdB 13 (blue), and VdB 16 (blue).
Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 50 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken on Nov. 20, 2019 under Bortle 2/3 skies. This dust is faint - I pushed the data pretty hard; APP was great for maintaining good color despite the pushing.
Target:NGC 2023 LBN954 Horsehead Nebula emission and reflection nebule in the constellation of Orion at 1300 light years distance.
Location:Multiple nights Jan 2021 St Helens UK B8 passing clouds, moon 59% to 76%.
Aquisition:34x 180s Ha, 21x 180s (OIII), 17x 180s (SII), total integration 216 min.
Equipment:Capture: Skywatcher Esprit 100ED, HEQ5, ZWO ASI160MM Pro, EFWmini with Baader NB Filters.
Guiding: Skywatcher 9x50 Finder, ASI1200MM.
Software:Aquisition: NINA, PHD2.
Processing: DeepSkyStacker, Siril, Starnet++, Photoshop.
Memories:A few setbacks on this target. Obstructed view south so 4 shorter imaging sessions one of which, with the best data, was deleted off imaging pc by mistake before being transferred to processing pc. Clouds resulted in more lost frames and the moon affected the contrast on the (OIII). During processing, Photoshop crashed loosing 3 hours of work which had to be repeated. Still happy with the end result though.
Taken with a TMB92L, Hutech-modified Canon T3i DSLR, Orion SSAG autoguider and 50mm guidescope, and Celestron AVX mount. Consists of 35 120-second light frames and 31 120-second dark frames, all at ISO 800, as well as 35 flat and 50 bias frames. Captured with BackyardEOS, stacked in DeepSkyStacker, and processed in Photoshop.
