Last night was the last session after a whole week of clear night time skies. Almost unheard of. The almost full Moon was 90° away so I'm pleased to have got a half decent image. I've used the same flat frames for a week now and there is evidence of new dust halos. The dwarf Galaxy in the corner is the Garland Galaxy, NGC 3077. M82 is just out of frame.

Galaxy season is upon us and South East England is experiencing uncommonly clear night time skies. This is Messier 101, the Pinwheel Galaxy in Ursa Major. Another one I've done before but not in wide field. A couple of years ago there was a supernova in one of the spiral arms that was clearly visible as bright as one of the foreground Milky Way stars, but now it's faded. This is just over four hours of four minute exposures from last night captured with LRGB filters.

Messier 51, also known as The Whirlpool Galaxy is interacteracting with a companion galaxy. The pair are 31 million lightyears away in. M51 was the first galaxy to be classified as a spiral galaxy by William Parsons, 3rd Earl of Rosse, using his 72-inch reflecting telescope at Birr Castle, Co Offaly, Ireland, he found that the galaxy had a spiral structure, the first "nebula" to be known to have one. I went to Ireland and visited Birr Castle and the telescope, known as the Leviathan of Parsonstown for my 60th birthday. I'm always reminded of the trip when I see this galaxy! I've imaged this one before at a longer focal length but I like the wider field of view I'm using now.

The Orion Nebula
Messier 42
NGC 1976
Orion
08/01/25
The Orion Nebula M42 is a diffuse nebula in Taurus just below Orion's belt. It is one of the brightest nebulae and is visible with the naked eye. My mount refused to guide so I captured this one with 30 second exposures. 144 x 30 second LRGB. 1 hour 12 minutes total exposure. Humidity and frost ended the session again.

One more to add to my Sky Searchers Astronomy Forum Messier quest. M46 is an Open Star Cluster but it has the additrional bonus of a small Planetary Nebula too. My mount was unable to guide for some reason and the plan was to capture 30 second exposures but I forgot to change the exposure times in the NINA sequence so this image was captured using 3 minute unguided exposures. 18 x 180 second LRGB. 54 minutes total integration.

The Phantom Galaxy

29/12/24
I did 15XL 5XRGB @ 2 minutes each then copied them all so that PI could stack them. This one would have been better in the SCT but I used the refractor since it is on the pier! So with that and the limited integration, I was quite pleased with how it came out.

The Pleiades
Messier 45
Taurus
29/11/24
I set up just to calibrate my guiding as I put the wrong focal length into PHD2 last time! And mist was forecast for 18:00. The guiding calibration went well and the mist stayed away so I managed another go at M45. This time I used two minute subs and got a better result than the last attempt using one minute subs. My NINA sequence was capturing 9xL, 3xR, 3xG, 3xB for five iterations. Then I packed up, not wanting to subject everything to any more 99% humidity. I got almost three hours integration.

The Omega Nebula
M17, NGC6618
Sagittarius
30/07/24
M17 was sitting at or below 25° altitude so my expectations were not good. But I was well chuffed with how this came out, all things considered. I might try getting some more data on this one to give it the attention it deserves. 30ish x 120 second frames.

Here's the First Light image using my new ASI1600MM and LRGB filters. It's also the first LRGB image I've captured or processed. It's also the first image I've captured with the newly re-greased CGX.
With my mount uncertainties, I chose M31, or to be more specific, the core of M31 as it's viewable from astronomical dusk to dawn without requiring a meridian flip. I set up a simple NINA sequence with no dithering, repeating until astronomical dawn. I kept it a bit too simple, I forgot to add a line for the auto focus routine! The mount took a couple of hours of calibrating and guiding assistant tweaking before it was happy to go. The guiding was poor all night, caused either by my sickly mount or the sickly seeing sitting directly under the jet stream as southern England was on the 19th. Or a combination of both.
Processed in Pixinsight after watching The Lazy Geek's My Simple LRGB Processing Workflow, an excellent tutorial.

64 x 60 seconds unguided
A supernova was spotted in the Pinwheel Galaxy which was the incentive to capture my unfinished observatory first light image. I didn't manage to get the guide camera focussed so this is composed from 60 second unguided images. The supernova is at 10 o'clock at the start of the spiral arm. It's my first capture since August last year, a hiatus due to undergoing and recovering from radiotherapy. It's great to be back in the game!
