2" filter wheel vs filter slider
Hi all,
I've been toying with the idea of getting a 2" filter wheel or filter slider for my 16" collapsible dob. I've previously had a 1.25" filter wheel for my 8" dob with limited success due to lack of in-travel, which I'm currently revisiting with a few modifications. Do any of the clever people on this forum have any opinion as to whether a wheel or slide would be the better option for the 16", or whether both are a waste of time/money due to inherent dob focuser issues. Not really looking (at this stage) for a slider which mounts inside the OTA. Cheers.
