Cone Nebula and Christmas Tree cluster

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

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
