And with short subframes for DSOs, we need a lot of storage space for every type...

Hi cytan,

In Singapore, if the nights are clear, there will usually be passing clouds also. So always try to make your subs shorter than longer so that you throw less subs away. In this way, 3 hours of integration per clear night is possible.

Hi guys, Just a quick bump by including this link to a CCD filter calculator: https://astronomy.tools/calculators/ccd_filter_size In this way, you can calculate if 1.25" filters work for your system. For example, a Redcat 51 with 183 camera and a filter-sensor distance of 28mm, is roughly the l...
