This trio of galaxies in Leo lie some 30 million light years away and form a great spring target for midsized telescopes. The 90 minutes I shot last night was neither better nor worse than this version from last year:

www.flickr.com/photos/124244349@N07/40734269251/in/photos...

So I combined the two, simply averaging this year's image into last year's (literally -- the Pixel Math function in PixInsight enabled me to add the values of each pixel and divide by two). There's no dramatic increase in detail but the averaged image has a cleaner, less noisy look when you click in for maximum resolution.

Captured with SharpCap Pro from my yard 10 miles north of New York City, and processed with PixInsight.

REALLY loving being able to shoot DSOs with my 8" Celestron Schmidt-Cassegrain. The Celestron Starsense Autoguider is a gamechanger in enabling me to shoot with the 8". GoTo and autoguiding is spot on. Utilizing the BlurXterminator tool in PixInsight during processing just polishes it off. Look at those dust lanes!

Discovered by Charles Messier in 1764, M20 is a star-forming nebula located 9,000 light-years away from Earth in the constellation Sagittarius. Also known as the Trifid Nebula, M20 has an apparent magnitude of 6.3 and can be spotted with a small telescope.

I mount my Nikon lens and camera on top of my optical tube at the moment. There was a constant wind of ~5mph last night when I took my images. I did 33 light frames and used the best 90% for 30 frames. I polar aligned with SharpCap and began guiding. The graph looked good so I started imaging. The stars seemed to stay in focus so I upped my exposure to 212 seconds and let it go to work. After stacking the files in DeepSkyStacker I pulled the TIFF file into Photoshop and mostly followed along to AstroBackyard's Rosette Nebula tutorial, making some of my own adjustments where they were needed. I'm still struggling with color of the surrounding stars. My WB was set to automatic, that might be why the color is a bit hard to manage. The Moon did rise while I was imaging and I can see a difference in my light frames, I'm sure I can do better and might try again during a new moon. But for my first time trying M101 and autoguiding I'm pretty happy!

Hot young stars abound in this region on the boundary between the constellations Cassiopeia and Cepheus. The Bubble emission nebula in the center is formed by the solar wind emanating from one such star, pushing against a cloud of ionized hydrogen which glows a characteristic red. To the right, star formation region NGC 7538 also glows red. At the upper left, open cluster Messier 52 shines brightly.

Towards the end of totality. This is a stack of 5x4 sec sub-images taken with a QHY183c camera and an Astro-Tech AT60ED at F/4.8. Acquisition with SharpCap 4 with LiveStack.

This is 144 x 30 second images of the comet aligned on the comet nucleus. It shows the background stars streaking across the comet's path - there are breaks due to pausing acquisition for passing clouds, recentering the image and dithering the guide scope (a technique to reduce hot pixels and other sensor errors). I probably shouldn't dither for comet acquisition!

Any exposures longer than 30 seconds caused unacceptable elongation of the comet nucleus. The comet was moving quite quickly across the night sky at about 9 arcminutes per hour.

The comet's dust tail can be seen but its faint ion tail has been obscured by bright Moon light on the night this image was taken - 4/5 Feb - despite having the equivalent of 72 minutes of data on target.

The colour of the background stars can be readily appreciated.

I used SharpCap 4.0 for image acquisition and PixInsight 1.8.9 comet alignment tool to produce this image.

7x4 sec images LiveStacked in SharpCap v4. It was difficult to get the color right on this, since the stacking process for an eclipsed moon does weird things. I tried this last eclipse but only got 4 to stack before I noticed blurring. There was a little with 7, but an unsharp mask filter fixed it.

Here is a view of the famous double cluster in the constellation Perseus (between Perseus and Cassiopeia), they are also designate NGC 869 and NGC 884. Check out the red supergiants in this view! Did you know that the Perseus Double Cluster is surrounded by one of the largest concentrations of red supergiants stars in the sky? (Red supergiants, neutrinos and the Double Cluster, Tristram Brelstafff, 1996). Also in this image is a visitor, Comet PanSTARRS (C/2017 T2), you can find it just right of center as a greenish blur with a little tail pointing to the upper left.

Captured using SharpCap v3.2. Image date: January 29, 2020. Location: The Dark Side Observatory, Weatherly, PA, USA.

Taken on the night of 4/5th February 2023 over a 2 hour period. 144 x 30 second exposures were taken (some breaks for cloud) and every 4th exposure selected for stacking. The session was run over the full Moon which has probably obscured some fine detail.

Longer exposures caused unacceptable blurring of the comet nucleus so I upped the gain to 160 and used short 30s exposures.

PixInsight's Comet Alignment tool tells me that the comet nucleus moves by:

-441.52 pixels per hour in the X-axis

322.46 pixels per hour in the Y-axis.

Since I know the scale of this image, I can convert that to arcminutes per hour

-11.9 arcminutes per hour

8.7 arcminutes per hour

For reference, the Moon is 30 arcminutes across.

Sharpless 101 (Sh2-101) is an emission nebula located in the constellation of Cygnus. It is also known as the Tulip Nebula as it resembles the outline of a tulip. Originally catalogued by astronomer Stewart Sharpless in hi 1959 catalogue of nebulae. It’s distance form Earth is approximately 6,000 light-years.

Look to the right of the image to see a blue arc which is the shockwave created by a jet of energetic particles emanating from a black hole sited in the microquasar Cygnus X-1.

A very difficult target for me given it's low altitude from my location. It's also a mere 61 million light years away, so...

NGC 1300 is a barred spiral galaxy located about 61 million light-years away in the constellation Eridanus. The galaxy is about 110,000 light-years across. It is a member of the Eridanus Cluster, a cluster of 200 galaxies. It was discovered by John Herschel in 1835.

Imaged with a 1965 3.5-inch Questar Quartz Standard Maksutov-Cassegrain telescope. The camera was a ZWO ASI224MC and a 2x Barlow (a Celestron Ultima SV-Series).

This was the best 20% of 7554 frames captured in SharpCap 4, pre-processed in PIPP, then analyzed and stacked in AS!3, with wavelets in Registax 6.

Read about using fewer subs but getting a higher quality overall result. Seems to work! Same subs captured a little while ago, using only 50% of what was captured.

The Leo Triplet (also known as the M66 Group) is a small group of galaxies about 35 million light-years away in the constellation Leo. This galaxy group consists of the spiral galaxies M65, M66, and NGC 3628.

Here is a composite image showing how the view of planet Venus is changing just from April 28th the May 13th, each night forming a thinner crescent shape. I’m now at the point where I must image Venus during the day because it is too low after sunset to image from inside the observatory. Hopefully the weather will cooperate and I'll be able to add a few more pics to this series.

Another take on this interesting and bright feature a bit off the beaten path in Cygnus, where a nebula filter brings out wide regions of hydrogen clouds, glowing red for our electronically enhanced viewing pleasure.
