The first thing that jumped out at me regarding the final image is that your post processing is very good. I think it brings out the nebulosity to great effect and overall it's very tastefully done.

Very interested in this. I’m a long time photographer just starting to branch out into Astro. As such I have a selection of big white Canon lenses including the 500/4L mk2, the newer lighter version of that lens. I have seen very little output using those lens, so this was excellent. Out of interest what camera was that? I’ll be using a 5D4 (un modified)

Might I suggest stacking the 2 different nights using deep sky stacker - SIRIL doesn't really let you stack 2 nights unless you use SIRILIC, stack both nights with the separate flats, in deep sky stacker in 2 different groups then import the FIT32 file into SIRIL to process - means you won't lose a fair amount of data.

The final image was rather good to my eyes, I think the star shape near corners are a result of field curvature as the lens is very fast, so you need field flattener to fix it! Thanks for sharing.

Mate, that is incredible! I have a canon 500mm that I got mint for just over £3k. I prominently shoot wildlife, but I'm soon moving to the countryside and wanted to have a blast. Could you give me a basic run down of what else I would need apart from the lens, camera and tripod? Would really appreciate your advice as there is limited information online about the 500mm for astrophotography. 👍 Cheers.

beautiful final shot,what is the foot on your 500mm canon to your mount

The video was rather long, but pretty awesome image! I'll like and suscribe.

Intrigued by the title so I watched. I got caught up in how many times you said "Um" that I had a hard time watching it. I bet if I went back and counted, you said it well over a hundred times. Good job but you have got to quit the Ums. PS. Great image of the Heart! Keep going.
