This is 450x60 seconds of Ha, 270x60 seconds of OIII. Shot with ASI1600mm on 11” RASA with Baader f/2 filters. Shot near/on full moon, lights clouds while doing the OIII. Clouds kept me from doing the SII, so processed bi-color in PI, some touch up in PS.

Thank you. I’ve never done a mosaic, but this would be a great one to do.

First time I see 60s for NB. This RASA is really fast!
How did you choose 60s? Following 10xRN^2 criteria?

It is possible to see the image at 1:1?

I pick the exposure time, just by eyeballing it. I try to pick low enough that the stars aren’t completely blown out. 60 was pushing it, probably should be 20-30. I’m fairly new to NB, so have a was to go.

 

I’m not familiar with “image at 1:1”. If you can elaborate, I’ll try to comply.

 

Thanks

Sorry, maybe I didn't explained correctly. I meant to see the image at full resolution. Did you uploaded it to astrobin, for example?
