How much exposure is needed to image NGC300 ?
I did nearly 2 hours last night through the Lunt 102mm, F7 and the 1200D at ISO 1600 with 80 second exposures. Did a quick stack and the galaxy is barely visible, seems to need quite a few more hours.
I understand it's a face on galaxy so surface brightness is a lot lower but I had to really push it with Photoshop to see anything at all.
