I have the cluster bug :)
Spent a good amount of time recently testing a bit of kit that effectively converts my EQ5 to a Goto, and now using EQMOD in conjunction with PHD for guiding. Working well, and for £90 (and in the true spirit of budgetastro) I'm more than pleased :)
Found this cluster while I was zipping around the heavens playing with the Goto, and fell in love with it. M35, aka NGC 2168 in the foreground, is about 2.8K light years away, quite young at 150m years (hence the blue stars) and contains about 2500 stars. NGC 2158 (above right of M35) is about 10K lights years away and is ten times older than M35 (hence the orange stars). It contains many more stars than M35 but in roughly the same volume of space (30 ly wide), so looks more like a globular cluster. Nice contrast :)

M97 the Owl Nebula, is a planetary nebula in the constellation of Ursa Major, The Great Bear.
Estimated to be about 8,000 years old it lies just over 2,000 light years away from us. It's given the monicker 'Owl Nebula' because of what looks to be a round face with two big eyes.
M108, also in Ursa Major, is much further away at approximately 46 million light years. This barred spiral galaxy gets the nickname 'Surfboard galaxy'. This edge on galaxy is thought to have a black hole at it's core 24 million times the mass of our Sun.
Both objects were first discovered by the French astronomer Pierre François André Méchain in 1781. Discovering M108 three days after M97.

IC 1396A - The Elephant's Trunk Nebula, or even more unofficially the lady walking away, Mufasa on pride rock, I mean it looks like anything you see.
This is a dark cloud of dust and gas in a much larger cloud of ionized gas illuminated by a very bright massive star (HD 206267).
Shot the "blue" data last night using my Esprit 100ED S-APO, the lack of Moon meant I could get some detail and contrast, though the OIII component to this nebula is very faint.
Was a great night to just sit on the beach whilst my scope imaged and watch Orion rise over the cliffs and see a small number of "shooting stars".

This is enough data so i could use only basic processing in PI: DBE, HistogramTransformation, a little SCNR to remove green and a little curves adjustment. So no BackgroundNeutralisation, no ColorCorrection, no Noise reduction etc.

The Milky Way soars over Lady Mountain in Zion National Park.
I stacked 8 30-second exposures (and 3 dark frames) using DeepSkyStacker. This helped reduce noise and allowed me to aggressively process the resulting image. This is my first attempt at doing this, so I'd appreciate any helpful feedback.
The foreground was processed in a second pass through DeepSkyStacker, without de-rotation, and the result masked into the sky image.

M42 - THE GREAT ORION NEBULA AND RUNNING MAN - Jan 2021
Ok, this is my final version of this subject for this year. I added another 2 and a half hours of data, to make this a total final exposure of 5 hours.
This is an HDR image created by blending 3 different exposure lengths after stacking and initial processing in Photoshop. It is the first time I've really tried to complete a full HDR image and I think the core of M42 has turned out OK. You can still see detail in the bright Trapezium core region, as well as still seeing fainter details in the outer nebulosity.
I am super happy with the look of this final image, it's muted and has a slightly dreamy colour balance, some will say I've pushed the data too far, but I like it.
Thanks for looking and sharing, comments always welcomed.
Clear skies.

This, I am reliably informed by my software, is the cluster M34 aka NGC 1039, chillin' up there somewhere in Perseus. With some spikes of course, to make it a little less uninteresting. Charles Messier must have had bloody good eyesight!

M57 (NGC 6720) is probably one of the most recognizable Messier objects. It is a planetary nebula found in the constellation Lyra, referred to as the Ring Nebula, and lies about 2,300 light-years from Earth. M57 is the glowing remains of a sun-like star. The star expelled a vast envelope of ionized gas before becoming a white dwarf.

Night shift today with my son Kevin. The green dot on the top right is the comet "Leonard". It passes the earth only every 80,000 years (!) and is visible this year from late November to early December. Unfortunately the weather is very cloudy, we have been watching the weather forecast for days and saw last night that this morning could be an opportunity with a lot of luck. So we got up at half past four and searched. After about 30 minutes we had found it. Then made a total of 120 pictures each 4 seconds and stacked them with DeepSkyStacker. Lens was the "bokeh master" Sigma 105/1.4.
[edit: reprocessed]
Ho usato solo lo spianatore con il 102 a 700mm, sono molto contento del campo ai bordi :) ma si sono generati due strani flare che erano già comparsi con la foto delle Pleiadi di settembre, chiaramente non ho la benchè minima idea di cosa la generi, forse il filtro skyglow, nelle due foto ho usato due spianatori differenti..

The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years from Earth in the constellation Ursa Major. The giant spiral disk of stars, dust and gas is 170,000 light-years across — nearly twice the diameter of our galaxy, the Milky Way. M101 is estimated to contain at least one trillion stars. The galaxy’s spiral arms are sprinkled with large regions of star-forming nebulas. These nebulas are areas of intense star formation within giant molecular hydrogen clouds. Brilliant, young clusters of hot, blue, newborn stars trace out the spiral arms. (ref: Wikipedia and NASA)

Comet ATLAS C/2019 Y4, discovered in December 2019, has been quickly increasing in brightness over the last few months, and many of us hope that trend will continue; past projections put it as reaching naked-eye brightness this April or May. However, it's brightness has recently plateaued around magnitude +8. That and an elongated nucleus suggest that it might be disintegrating.
It was likely about magnitude +8 when I photographed it last night, April 9th, near Star 42 Camelopardalis. I'm not sure what the faint nebulosity is to the lower left of the comet: either Dark Nebula HSVMT 25, integrated flux nebula (IFN), or it's simply an artifact. Galaxy NGC 2366 is also apparent in the upper right corner.

A spiral galaxy in the constellation Camelopardalis.
It goes by the nickname of the Hidden galaxy as it's a very difficult target for visual and for photography. This is due to it lying pretty much in the same line of sight as the Milky Way and all it's bright stars and dust lanes. Except IC342 which is about 11 million light years further on.
