IC 4603 & IC 4604 (Rho Oph Triplet system)

IC 4604 is a large, blue reflection nebula located in Ophiuchus. The nebula is illuminated by Rho Ophiuchi, the triple star at the top center of this image.
IC 4603 is another large, blue reflection nebula located in Ophiuchus. The nebula is illuminated by HIP 80462 (vdB 105) at the bottom bottom right of this image.

1st Light to a new scope, TS-Optics CF102mm APO triplet.
Not sure I was 100% spot-on focus wise, didn't have a suitable mask for it yet, and no EAF atm.
I used it together with its massive flattener/reducer 0.8, designed for FF (this baby carries a 3 inch focuser), and stars were pinpoint side to side.

I may sound like a scratched record, but I love your processing. Not too overly stretched, no artifacts and just very nice.

That's the kind of records I like, Vince! 😉

Yes, since I started astrophotography, I've been told that a lot, since a lot of people like to over-process at times, you gotta work with the data..., go with the grain, not against it 🙂

Much appreciated!
