Prepering for galaxy season - Sharing the pain

Thought I would share my learning with you as my first galaxy season. Hopefully it may help some others trying for the first time too.

Took some subs in preparation for getting the RC out so I could start to learn what I need to do!

Lessons learnt so far.

1. Take shorter RGB subs as @ 600 seconds the light pollution was unrecoverable. Will also improve star colour. I lost all IFN in LUM due to RGB pollution.

2. Take shorter Lum exposures for cores. Then mask or HDR combo in.

3. For this target aware HA will also improve.

I will post updates as I get more data and see what the end results are like on this image.

And as an extra challenge trying all this with new FLI camera!

Rev A - First Pass

Rev B - A little reduction on some of the bigger stars.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
