This is NGC2841 The Tiger's Eye galaxy.

First discovered by William Herschel 9th of March 1788.

It's an unbarred spiral galaxy which can be found in the constellation of Ursa Major (the Great Bear).

It's 46 million light years away and approximately 150,000 light years across, so, quite big.

Imaged taken 5th of January 2022 from my back garden.

Located 6,400 light years away in the constellation of Orion, the Monkey Head is an emission nebula and home to the open star cluster NGC 2175.

The nebula acts as a womb for new stars to be born. Those new stars then radiate such immense energy that blasts in to the surrounding gas and dust that makes up the nebula. This has the effect of not only clearing away the surrounding nebula from the newly born star but, causes the gas and dust in other areas to be pushed together. When enough of this material is pushed together it allows gravity to take hold and pull more and more of it in. When enough of it is pulled together there's a good chance another star will be born.

My mount was polar aligned with SharpCap (what an amazing system for aligning). I'm not comfortable using my SCT as my lens yet. My solution is to piggy back my Sony a7RIII and adapted Nikon 500mm f/4 on a ADM dovetail rail on the top of my optical tube. I had to throw away about 5 frames due to satellites passing through or near my targets. This was low on the horizon and when I came out to end my imaging session I found my guidescope not being able to guide and had to delete my last 3 frames becasue the images were not sharp. It was a fun learning experience, looking forward to trying again when this target is higher in the sky.

My first reasonably successful photographic meteor hunt! Took a nice spot at the beach, set up the camera and enjoyed the Perseid meteor show. 4 of them also ended up visible in the 89x 30s frames acquired using the Samsung NX30 with the 16 mm f/2.4 wide angle lens (stopped down to f/3.2 to reduce distortion at the edges). ISO setting was 1600. The camera was mounted on a clockwork barndoor tracker. Post-processing included stacking the 60 best frames for the starfield background in DeepSkyStacker, as well as 4 consecutive images each with manual alignment in Photoshop for the sea and tree foreground. Finally the correctly aligned meteors were masked and mounted back into the image.

Barnard’s Merope Nebula (or IC 349) is located directly adjacent to the star Merope, often this area is heavily exposed burying this tiny object in the bright majesty of the Pleiades. It is listed as a 13th magnitude (visual brightness) nebula and is very close to Merope (about 0.06 light years). Merope is providing the dramatic lighting effects that you can see in the APOD image listed below.

Tech Specs: This image is composed of 32 x 15 second images at ISO 3200 with five dark and five bias frames. Meade LX90 12” telescope, Celestron CGEM-DX and Canon 6D camera at prime focus. DSS and ImagesPlus for processing. Imaging was done on November 4, 2016 from Weatherly, Pennsylvania.

My solution is to piggy back my Sony a7RIII and adapted Nikon 500mm f/4 on a ADM dovetail rail on the top of my optical tube. I'm still new to autoguiding. I got some great detail of a galaxy with 3:30 second light frames. For this I stopped down the aperture to get diffraction spikes on the brighter stars and exposed my lights for 4 minutes. I used DeepSkyStacker to combine all frames and then processed the TIFF file in Photoshop using my skill set and relying on the famous Astronomy Tools Action Set.

M15 Globular star cluster.

First discovered in 1746 by an Italian named Jean-Dominique Maraldi. It's approximately 33,600 light years away in the constellation of Pegasus. M15 is one of the densest clusters yet discovered with many very hot blue stars and many of the cooler orange stars becoming more concentrated towards the core.

It was the first of only four globular clusters found to be hosting a planetary nebula. The one in M56 is named Pease 1, after it's discoverer Francis G. Pease in 1928.

It's also thought to contain a black hole at it's core, estimated to be 4,000 times the mass of our Sun.

I also had a little play with the 3D module in StarTools. It looks great using the cross eyed method, but when I save it then try loading to Facebook, it doesn't come out very well sadly.

Took the image with a Skywatcher 8" quattro and a Canon 1100D. Along with some other bits n bobs and lots of images stacked together. Processed everything together with DeepSkyStacker & StarTools.

Had a session on M42 the other night whilst testing the guiding on the QHY5 I've just acquired (works), and having done M42, and done it again, and again, I thought I'd drizzle into this. Only 19 subs before it disappeared behind a tree, so very noisy, but colourful nonetheless :) I really need a longer focal length, and a lot more subs, to do this justice.

Designated NGC 1973, 1975 and 1977 (the seventies), but more commonly known as The Running Man Nebula, this is just north of M42 in Orion.

Memories:Third target imaged before sunrise on a fine clear night.

A target I've been wanting to image for a long time, never had enough focal length until I recently had access to a 400 2.8 from Canon.

Shot using stock Canon 6D, EF 400mm 2.8 IS III and Skywatcher EQ6R Pro (unguided)

Imaging with stock cameras isn't ideal, thermal noise is a real problem after the exposure times needed. The longer exposures needed to get a reasonable signal really heats up the uncooled sensor. Mine during these summer months has hit 35-40c regularly which creates awful noise.

Getting as much data as possible helps lower these issues, but doesn't eliminate it. However, shooting with modern DSLRs does result in achieving star colour relatively easier compared to 12 and 14bit astro cameras.

This image is comprised of 21x600s Ha and 24x60s RGB exposures.
