Astrobin EDIT: HOO Revision It seems like since a recent Seestar firmware update, the S30 Pro in NINA was no longer limited to the same 60s available in the Seestar app with EQ mode; it’s now up to 2000s like the S50 already had. I originally wanted to learn NINA for long exposures with this scope, so after this update I spent a day working through the setup. After polar alignment, I tried a few targets between 60s and 600s. When using a 3nm Hα/OIII filter (SV220) with NGC 7000, I got some surprising results from just a few 300s subs. Being used to this filter at 60s, I expected much fewer stars and I was very happy with having this much OIII in just half an hour.…
