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.

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

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.

4 x luminance, 4 x red, 4 x green and 4 x blue at 180 seconds

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!

This was my first ever proper deep space stacked image. I was really chuffed with it at the time!
