Description

This is my first attempt at the Rho Ophiuchi cloud complex.

I learned a couple important lessons on this one. First, I don't know what other people's experience is, but I have found it challenging to get a polar alignment that is very accurate with a Star Adventurer, so there is quite a bit of walking noise in my image. Second, I shot this image using a light pollution filter, so I lost quite a bit of the yellow. I'll definitely be revisiting the target again, so these are things to keep in mind for next time.

I captured this with my "portable" setup, consisting of a tripod, DSLR (Canon 200D, modified), and Rokinon 135mm lens.
