PixInsight - Stacking and image processing. It's pricey but really the best processing software out there for deep sky pics imo (DeepSkyStacker / Siril / GIMP are commonly used free alternatives). Source: almost 2 years ago

Dear friends of Asahi, I was planning to get a laptop mainly for astrophotography postproduction while traveling, and other normal tasks. Apps required for astrophoto elaboration are just 2: PixInSight and Gimp. An M1 cored MacBook seem a very good machine but I really dislike macOS. I was wondering before spending time and money looking for suitable offer from refurbished market if Asahi Linux should run both... Source: almost 2 years ago

Subs were calibrated and integrated for each filter using SiriL. In PixInsight I started by cropping the three stacked images, used automatic background extraction, and then combined the three into a colour image. BlurXTerminator on the combined image and StarNet v2 to separate the stars.. Separate multi scale linear transform on starless and luminance, more aggressive on the starless image. Unsharpmask applied to... Source: about 2 years ago

You can stack images if you want a cleaner result. https://sites.google.com/site/sequatorglobal/ is a good easy to use option. Can also do panoramas or both. Use something like stellarium to find something you want to photograph. clearoutside.com can help with weather and moon phases. Make sure to shoot when there isn't any moon light. https://www.lightpollutionmap.info/ can help finding dark locations. Photopills... Source: almost 3 years ago

If you are a windows user, you can also use the program sequator (https://sites.google.com/site/sequatorglobal/). It will line up the images for you, and you can then do post processing in photoshop to improve whatever you need to to get the colors and images right. You can also add in dark images to remove camera noise. Really sweet program for night photography. Source: almost 3 years ago

It's 30 x 15s exposures at 1600 ISO, all stacked in Sequator, which is free software that tracks stars and allows you to accurately stack images despite the stars moving. There was a little editing afterwards, but nothing major, the stacking does most of the work. Source: about 3 years ago

I recommend you test your star tracker mount to see how good/bad is the periodic error, etc. One example of how to test: Https://philhart.com/content/star-adventurer-review#:~:text=Performance,minute%20period%20of%20the%20worm. Then you can do some math: if my tracker error is X arcseconds, and my camera pixel size is Y microns...I can use a lens of Z focal length and only have star trailing of W pixels. (And...

What you can also do, is take many pictures and stack them using a free software like Deep Sky Stacker or the simpler and also free sequator . By doing that, this will reduce the noise of the higher ISO and will help you edit your photos better. Source: about 3 years ago
