I have far more filters than slots and I really don't like my manual filter wheel. So here is what I've decided. I'm going to dedicate my home kit to two tasks:
  1. Photometry[/*]
  2. Scouting for targets for RoboScopes if possible.[/*]
And I'll use RoboScopes for:
  1. LRGB[/*]
  2. Narrowband[/*]
With that said I can get away with five filters:
  • Slot 1: Luminance (for faint variable stars and exoplanets)[/*]
  • Slot 2: Photometric V (for bright variable stars and exoplanets)[/*]
  • Slot 3: Wratten #12 (for detailed monochrome imaging, and for scouting for RoboScope targets)[/*]
  • Slot 4: Ha (for scouting)[/*]
  • Slot 5: Dark[/*]
What do you think?

By the way, my scope is a William Optics ZenithStar 71. It was marketed as "APO-like" due to the ED glass. Take my word for it, buy a real APO. Blue light is terrible while red and green focus very nicely. With this defect blue stars come out fat and bloated which really detracts from the subject. I've discovered that using a Wratten #12 (i.e. minus blue) does a wonderful job.

Thanks,
Brian

Sounds sensible to me even putting to one side any fiscal element Roboscopes may benefit from ?

I agree on cheaper so called APO’s as I in the past have also been in the same boat. They just don’t cut the mustard!
