Have you noticed how advanced Gimp has been with the new version 2.10 ?
Now it work perfekt to open Fits 32 bit floating point images and process them. I have tried this many times earlier but it never worked very good. Now it's like a dream to work with.
I'm in the learning process how to use Gimp's capabilities. I have now got the opening process of three grey rgb images to work. It's of course not very complicated, but for me who never used Photoshop or something simular it was and I had hard to find a tutorial for the new version.
I have now made a tutorial for this first step how to start with Gimp and open 32 bits separated color images:
If you already working with Gimp, have you found something of special interest ?
Hello! I have a question on how can I mount my camera to my Sky-Watcher Starquest 130P telescope? I’ve watched so many videos about it and there’s so many different answers on what I need to do that. At the moment, I have 2x Barlow lens and a DSLR. I know that a T-ring is also necessary but is there anything more? Any help is highly appreciated, thanks! (I’m really new to telescopes and astrophotography in general so I hope I don’t say anything dumb)
So, although I had some issues with my auto guiding (which I found out afterwards) I did manage to get 9x180s exposures and 5 darks of Andromeda and give both stacking (using DSS) and processing (using GIMP).
My first attempted DSO....
I am pretty sure that people could get far more information out of the TIFF file from the stack.
Hopefully I will get another clear night soon. I am in a heavily light polluted area so I do have a clip in filter on my DSLR which I think took a lot away.
More practise needed!
Just thought i'll bring this up as a point of discussion. Today, cooled CMOS Astro Cameras are available in plenty. QHY, ZWO and other variants of the same camera are selling for very reasonable prices. However, there was a point of time when astrophotographers used to cool down their DSLR's as a cheap OSC alternative to CCD cameras. Give a choice, I would've purchased a dedicated CMOS OSC which can cool to 40 C below ambient, but since I had a Canon 500D which I had self modded, I requested a friend Kaustav Chatterjee (an avid model railroader) to cold mod my 500D (he had cold modded his 1000D long back). This newly modded camera has a TEC12703 single peltier and cools to approximately 20 below ambient.What do you guys think?

This is 6 hours (30 x 12 min), taken with my modded Nikon D7000 @iso200 and Astronomik 12 nm Ha 2" filter on Meade LX200-ACF with reducer (=1600 mm FL @ F8). Guided with NexGuide on HEQ5 Pro.
The plan was to do a Ha O3 bicolour on this target, but the O3 may be a future thing due to weather conditions.
I usually remove the stars during part of my processing workflow and put them back later on, but this time I think the nebulosity and dust came out best without them. I did however try to find out which stars belong to Melotte 15 and include only those, just to portrait the Melotte 15 without anything between it and us, but I could not find that info.
Processed with DSS, Starnet and PS.
