Over the last three night I chose this target not knowing how it would come out. The processing in Pix and Ps I get this, as we are about to get clouded in I have gone with the 100shots. Camera rotated to get this view.

The (relatively) small batch of North East Proms today with Earth for scale, best 30% of 2100 frames in AS2, bin2x2 - very fast moving low clouds and gusty (45mph+) squalls today, hid in the gazebo with the scope and held on for dear life until I got a break. Image rotated 90 deg CW. Skywatcher 120ED Esprit, Daystar QC, Grasshopper 3 (IMX174). Genika software worked for once too without falling over.
Also different configuration for scope, replaced the Diagonal with an 80mm extension tube (UV/IR filter attached to this), then the Quark, then the camera. Seems to work just as well and lets me have more back focus. For a sense of further scale, see here www.flickr.com/photos/76699751@N07/28517451253/in/photost...

Took advantage of an early start today from 08.50 UTC until 9.30 UTC conditions were great, total blue sky and hardly any wind until 10.00 UTC. What a difference too using the SW120 today with the Quark Ha eyepiece.
So this is a final goodbye to AR2403 disappearing around the western limb.

About 23 thousand light years away and 145 light years in diameter comprising of several hundred thousand stars. Most of these stars are incredibly old, about 12 to 13 billion years. Sometimes, as they are so densely packed together, they collide and make new ‘blue straggler’ stars. I can imagine living on a planet around one of these stars, you must not be able to see beyond the local cluster. (Wikipedia and Earthsky)

Notes: - Much as I have enjoyed taking galaxies I really wanted to try something different so had another go at the M13. I did some reading on this beforehand and a lot of people say they don’t overexpose as the core gets blown up. For this reason I took several 30s, 60s, 150s and 300s subs. In the end, the Star Tools Decon module did a really good job of bringing out detail in the core even with my 5 minute exposures so I have just abandoned my shorter ones.
Colour is a constant problem for me with my red/green colour blindness so I rely on the Max RGB option in Star Tools and my wife although I didn’t bother her in this process. In this case I cranked up the ‘Cap Green’ option, and took a sample of the core/nearby galaxy so I hope this is close to being right.
The amount of noise in this picture is annoying me. Another go may be required at some point, either to reprocess or to take the picture when its closer to the zenith.
Previous attempt for comparison:- www.flickr.com/photos/andrewsingleton/8721642768. 7 years ago and some new equipment has made a remarkable improvement on this old picture. This was my first ever attempt at astrophotography through a telescope.

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum-Centaurus Arm. It was discovered by Charles Messier on June 5, 1764 Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars, an emission nebula (a relatively dense, red-yellow portion), a reflection nebula (the mainly NNE blue portion), and a dark nebula (the apparent 'gaps' in the former that cause the trifurcated appearance also designated Barnard 85) Shot with Canon 60D on a SW Quattro 250 /f4 on a SW NEQ6 Pro. 7 x 30 sec frames and 5 x 55sec frames blended together in Sequator.

NGC 6744 55 x minutes of data taken with QHY 183C PRO on a Sky Watcher Quattro 250 P scope. NGC 6744 is an intermediate spiral galaxy about 30 million light-years away in the constellation Pavo. It is considered as a Milky Way mimic in our immediate vicinity, displaying flocculent arms and an elongated core. Wikipedia
IC410 is an emission nebula in the constellation of Auriga. Often called the Tadpole Nebula in reference to the two tadpole shaped clumps in the upper left of the nebula.
NGC1893 is the open cluster of stars in the middle of IC410. It's these stars that are ionizing and shaping the surrounding nebula. The tadpoles themselves could be collapsing in to new stars.
The nebula is around 12 to 12,500 light years away and 100 light years across.
The open star cluster is believed to have been formed 2 to 4 million years ago.

Ngc 7023 - Iris Nebula è una nebulosa diffusa che si trova nella costellazione boreale di Cefeo. Si trova a circa 1.400 anni luce da noi ed è caratterizzata da una magnitudine apparente di 7.7. Si tratta di una nebulosa a riflessione e cioè che riflette la luce di alcune stelle vicine. La ripresa è stata effettuata tramite l'osservatorio remoto personale 3Z @astrocamp insieme all'amico Giorgio Mazzacurati. Strumentazione Rc8 - g24000 Moravian su Eq6.

Last time I tried to shoot this region, it was last year. It took me almost 5 nights to tame the AZ-GTI. This time was clearly easier! It was a kind of revenge :D
I was supposed to shoot during two nights, but after processing the first night, it was clearly enough. (Even with a 90% Moon)
