Image Train and 2" Filters - 8" SCT
Hi,
I have setup the image train shown, which is exactly 105mm with an F/6.3 reducer, and ASI 294MC Pro camera.
I want to connect a 2" Optolong Pro filter, but don't seem to have the correct threads, nor size to add the filter.
Any ideas re what is needed ?
Regards,
Lance
