Hi everyone,
Recently i read something on the net about looking down the baffle tube of a SCT, from the imaging end, and seeing all of the secondary mirror, and this is where im unsure, maybe all of the primary reflection or something - I know, pretty vague, but Its a little vague in my memory.
It definetly said something about seing something in the secondary or around it
I think the issue was in relation to whether the secondary mirror and baffle tube sizes were right for each other such that all the light gathered by the secondary mirror is delivered to the focal plane.
Has any one seen such an article talking about this?
Im aware there are articles about the baffle tube being the correct design so it eliminates stray light - this isnt what am after, I found some of them while doing some searches for the above information, so if anyone would like to see these, i can provide a link.
Thanks
