After 3 years using a Canon 600D and the next 3 years using a ZWO 2600MC OSC in 6” , 8” and 10” Newts , I’ve decided to take the final step and image with a Mono camera, namely the 2600MM.
My Sydney location with Bortle 7/8 skies more like Bortle 8 with neighbours lights blasting my yard has finally prompted me to find a solution to improve my imaging as the OSC definitely has its limitations under less than ideal conditions.
Obviously my South Coast NSW Obs is located under Bortle 3 skies and therefore OSC and Mono both excel ( in their own way ) with broadband and narrowband.
I will still be using the 2600MC OSC from time to time but it’s time to take the plunge.
I’ll be buying Antlia LRGB filters and Antlia 3nm narrowband filters but I’m undecided between 36mm and 2”
Astronomy tools calculated my minimum filter size to be 32mm and that is based on the filter being 27.5mm from the camera sensor ( 17.5mm sensor to base of 2600MM plate + 10mm to filter ) ZWO filter wheels are 20mm thick
If I choose 36mm filters and filter wheel , that only gives me a 4mm tolerance ? Is that enough to avoid Vignetting etc…
If I choose 2” filters and filter wheel , this future proofs any set up now and in the future
There is a physical size, cost and weight advantage with the 36mm

Any personal experience and advice with the 2600MM and filters would be greatly appreciated

Cheers
