I everyone,
I've started Astrophotography about 6momths ago so I'm super new to this
I'm still with very simple and entry level tools
But thinking to get seriously into this
So far I've been using a canon90d unmodified a staradventurer pro and a sigma 150-600mm without autoguiding i was able to get this m31 and the orion nebula with only 45min exposure each with 2min subs at 300mm iso 1600
Since then I decided to get a zwo120 for guiding and a 30mmf4 scope paired with zenithstar61 and flat61
Followed all the instructions from william optics for backfocus and using bahtinov mask focus looks ok, autoguiding with PHD2 shows average error around 1.5"
Tried last night heart nebula and California nebula both have 3h total exposure at 360mm 4min subs iso1600 and in both cases results seems way poor compared to the sigma
Any advice on focus or backfocus if that is the issue ?
Thanks

Sigma 150-600mm for Deep Sky Widefield ?
in Getting Started With Imaging

I currently own a sigma 150-600 and have used for astrophotography paired with 90d
Since I only had a star adventurer as mount i could go any further than 300mm due to imprecise tracking.
Here some pics I've got with this setting hope this help
