I have finally decided to begin imaging with a mono setup, and this was the first light that I got with the camera! This image has just over 1 hour of integration time, and I'm very pleased with how it has turned out. I was hoping to get more than 1 hour worth of images, but something went wrong (I'm guessing after a meridian flip), and the rest of the images that night had lots of star trailing. I hope to figure this out the next clear night I have.

Wow. 585MM for my next guide cam it seems. That's super nice.

Phenomenal! Out of curiosity, how come 252 gain? Unity gain?

Thanks! And yes, unity gain (at least according to the diagram on their website)

that's some fantastic signal, I have the quattro 150p (basically same scope) but my signal is a lot worse kekw

#

good stuff

#

mono will be a massive QoL change for you

ZWO chooses to pick 252 for the 585 which Cuiv can't wrap his head around

#

a lot of people think it's way too high for unity gain on the camera

Interesting, wouldve thought it would be similar to the 571 or 533 at 100 gain

Yeah I was surprised when I saw how high it was

#

Yeah thats really high for a newer sensor. Full well drops HARD at higher gains too, so you're really not having a great time at 252.
