Problems with ice of dew somewhere, had to heavily crop this to remove rings and artefacts. Strange colouring also part of the problem. Not great!

M42 & NGC 1977 mosaic Dec 2020

2020-12-22T20:50:31+00:0020 December 2020|M31-60, Nebula, News, NGC Winter|

The annual M42 this year is a mosaic with the Running Man. APP dealt with the gradients really well after messing with the Normalisation and Integration parameters.

Reminder:

Mosaics in APP – defaults unless otherwise stated
1. Load – all as normal – you don’t need to use separate sessions for each frame if you did it all at the same time
2. Calibrate as normal
3. Analyse stars – I needed to increase from 500 or it wouldn’t work – went 1400 – might have been the subject but I suspect it helps to stitch the mosaic together
4. Register – Registration mode – mosaic, use dynamic distortion model, uncheck same camera and optics (will be suggested if you don’t)
Scale stop = 1 (for a 10% mosaic overlap)
5. Normalize – Mode – advanced – neutralize background
LNC degree – 2nd degree, iterations 3
6. Integrate – Enable MBB – 10% because I did 10% overlap in the mosaic
INTEGRATE – and if you’re lucky it all works

NGC 1977 test image

Testing out and configuring replacement laptop after old one got washed away in observatory leak! Took a few frames of the Running Man nebula. Topaz is great for removing noise in images with too few frames. This only had 4 frames and once stretched was very noisy. Looks great after Topaz-ing.
