Today I was looking for advice on what I can upgrade on my current gear, I have a budget of 1500 usd and I was looking to upgrade my astrophotography setup, I am going on vacations in the southern hemisphere and I am looking to upgrade my gear and also make my gear as light as possible.
This is my current gear:
Camera: Nikon D5200 (Full Spectrum), Nikon Z6 II (Stock)
Scope: Omegon 90/500 OTA (achromatic doublet)
Lenses: Nikon 80-200mm f/2.8 (Poor Optics), Nikon Z 24-70mm f/4 (Too Wide), Nikon Micro Nikkor 60mm 2.8 (Too Wide), Samyang 50mm 1.2 (Too Wide)
Star Tracker: Star Adventurer 2i (Complete with counterweight), Star Adventurer Mini
Tripod: Omegon Titania 600
Filters: 1x H-alpha 12nm + 1x O-III 10nm + 1x R+G+B+Y Set of Filters
Guide Scope: Nope
Guide Camera: Nope
I also wanna note that I do not own any laptop right now, maybe it would be better if I was getting a ZWO ASIAIR since it's compatible with mobile, and would allow me to do over 30 seconds of exposure with no star trails to get a better Signal/Noise ratio.
Thanks for your help.
