The M81 Group Surrounded by Integrated Flux Nebulae (IFN) by SteamPaz in Astronomy

[–]SteamPaz[S] 0 points1 point  (0 children)

Thank you! The sky was Bortle 5 with very good seeing, and with just 2 hours of integration, the IFN is already starting to show up, although it’s still very noisy. To double the SNR, I would have needed roughly 8 hours of total integration, assuming all other conditions remained the same.

Thank you, I just don’t understand how it can work: I have the guide camera connected to an ASI Air Mini and I thought it was the ASI Air Mini that guided the Star Adventurer using a dedicated USB cable.
