Taken with a TMB92L, Canon T3i DSLR, and Celestron CG-4 mount. Consists of 29 40-second light frames and 24 40-second dark frames, 25 5-second light frames and 25 5-second dark frames, all at ISO 800, as well as 11 flat images, stacked in DeepSkyStacker and processed in Photoshop.

I have photographed the Triangulum Galaxy over the years, but this is the first time I have attempted it with my Meade 12″ telescope. The galaxy extends further than what is shown in this image. I’ll attempt a mosaic image as I add more data to this view. Technical details: Total exposure time was 26 minutes using 20 second subs at ISO 6400. Images were stacked using DeepSkyStacker and adjusted using the software packages ImagesPlus, Adobe Lightroom and Corel PaintshopPro X5.

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.

Boring techie bit:

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).

"The beautiful spiral galaxy Messier 83 is located in the constellation Hydra and is also known as NGC 5236 and as the Southern Pinwheel galaxy. Its distance is about 15 million light-years, being about twice as small as the Milky Way". Source: eso.org

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! :)

This untracked image is a 22 x 4 sec exposures taken with a Canon 6D and 70-200mm lens at f/4 and 21800 iso, stacked using DeepSkyStacker and processed in Lightroom 5.

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.

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.

This is the cleanest photo I've taken of the Orion nebulae complex from the Flame and Horsehead nebulae to the Running Man and Great Orion Nebula (M42). This is a total of one hour's worth of exposure data (12 x 5 minutes) under a rural sky. I did use a light pollution filter to cut out the sky glow from the surrounding villages. I may tweak the colour saturation later. But I just wanted to show you how fairly clean it looks.

The open cluster NGC 2158 is one of those things that made me do a “double take” when I got back into astrophotography several years ago. Of course I knew about the open cluster Messier 35 (M35), but when I looked at my first DSLR photo of M35 and spotted that hazy little ball nearby, I thought I found something new, a comet perhaps….not the case.

NGC 2158 is located in the constellation Gemini, southwest of M35. While it looks like they are close together, NGC 2158 is actually around 9,000 light-years behind M35 (11,000 light-years from Earth). It has an apparent magnitude of 8.6.

Imaging was done on February 26, 2017 from Weatherly, Pennsylvania. The wide-field inset view was taken in 2014 using a Canon 6D and 400mm lens.

Comet C/2020 F3 (NEOWISE) imaged at around 01:41CEST on 19 July 2020 from the beach at Wassenaar in The Netherlands.

The weather was unhelpful, with clouds drifting through, and this is the best set I could get in the brief time before it was completely socked in. At least it shows the ion tail nicely, extending to 15º or more from the nucleus.

Nikon D7000 + 85mm lens at f/2, 40 x 3 sec exposures unguided at ISO 800. Aligned and combined in DeepSkyStacker, then post-processed in LightRoom.

The small purple squares around the brighter stars are probably linked to saturation in the CMOS detector, enhanced in this processing. The whole image is more "impressionistic" than accurate, colour balance included, but hey, we've also seen more than enough pristine Comet NEOWISE pictures, right? :-)

Canon 135 f/2 (stopped down to 2.8) lens attached to SX Trius 694 + Baader 7nm Ha filter piggybacked to main scope on a CEM60 was used to capture eleven subframes at 300 seconds each. Stacked in Deepskystacker and processed in StarTools and Photoshop CS2

Chinese astronomers in 1054 recorded a new 'star'. This new star was visible during the daytime for almost a month.

What they were actually witnessing was a supernova, the death of a star.

This particular star was about 6,500 light years away. They didn't know it at the time but, they were witnessing something that actually happened around 5,450 BC.

It's believed that the Crab Nebula is the remnants of that supernova.

M1 is six light years across!

It was first discovered in 1731 by John Bevis. M1 is what inspired Charles Messier to later start his now famous Messier catalogue. After he thought he'd found Halley's comet and realised it wasn't, he decided to make a list of things that weren't comets, and so therefore, not worth observing. Now, every astronomer and astrophotographer are fascinated by them.

BORING techie bit:

Captured using a Skywatcher Quattro 8" with f4 coma corrector on a HEQ5 mount.

Guided using an Altair 50mm guidescope and GPcam combo.

Canon 450D astro modified and with Astronomik CLS CCD APS-C clip in filter.

Location: Newhey, Rochdale, UK.

13 exposures of 3 minutes each. Stacked together with calibration frames using DSS and all processing done with StarTools.
