Hoping someone may be able to help me.
I just took possession on my first reflecting telescope ( an f3.8 Orion Optics AG-10). Have been a refractor guy for a while now.
I have the cats-eye collimation tools. The Telecat XLS site tube/Cheshire cobo and the infinity XLK collimator. ( one with central and offset pupil)
I have watched videos and followed instructions. I think I am reasonably close. Quite a learning curve I must say having never dealt with reflecting optics before.
Where I am at is as follows:
With the auto-collimator, looking through the center hole the hot dots are perfectly aligned. I then look through the offset hole each pair are not be perfectly aligned. If I get them perfectly aligned in the offset hole, they're not in the center hole.
To say another way, my radiation hotspot is centered in Cheshire and stacks are aligned in central view. Problem is in offset view they are not stacked . Once I adjust secondary to stack in offset view they are no longer stacked in central view and vice versa.
If I stack either central or offset with primary centered in Cheshire, my glatter laser puts laser dead center of the radiation spot.
I am just not sure why I cannot get offset AND central views to stack as per images and instructions. I have iterated back and forth between Cheshire for primary and Auto Collimator for secondary heaps of times.
Any suggestions what may be causing this and what I need to adjust ?

Quote:...I would suggest with the number of these fast imaging newts comming on the market that instructions for catseye tools have a waning about focal plane as it makes a HUGE difference....
Quote:One other question. In the collimation video Jason made on YouTube from catsey eye website and the photos here, what were these taken with ? Seems like somehow a webcam or something was used to project collimation live.
Quote:Does the howie laser have a sight window like my stock collimator?
Quote:So, I just looked on the catseyecollimation web page and was looking at the starterset XL. It comes with the hot spot , teletube XL, and blackcat XL cheshire. Is this alone sufficient for accurate collimation? It just doesn't look like much for $160
Quote:Here is my biggest issue with secondary positioning. I loosen the 3 screws and adjust the position to where it is circular. But when I go to tighten those screws again it all gets out of whack. Even to be able to access those 3 screws I have to hold the secondary holder in a weird position. Is there any tricks out there other than having my wife help? Would getting something like a bob's knobs help? Do those lose their collimation easier? If it were not for this step overall collimation would be a lot easier.
Quote:Thanks CatseyeMan. That worked pretty good and was a bit less painful. I've been thinking about getting one of your site tubes. I have an old Tectron set which is 1.25. I feel it works OK, but I may get a 2 inch site tube for my 10 inch just to be sure. However, I rarely use 2 inch eyepieces...partially because I only have one and it's a cheap 30mm GSO.Thanks again!
Quote:I do have a 2 inch / 1.25 glatter laser (quite nice in my opinion). But my site tube is 1.25. So I'll probably pickup a 2 inch site tube at some point. Do the Catseye cheshires work with the original donut hole center mark? Or do they need the triangle?
Quote:I've been reading in some of the archived posts where someone had loosened the center screw on there secondary mirror (z12) thinking this was how you adjust the tilt of the secondary itself. Now I know this is not so, but as i am awaiting my sight tube/Cheshire tools and Vics book, I was curious if this is how you adjust the secondary so that it is directly under the focuser? Can't wait to get my new tools and booklet for sure. Thanks ahead of time

Quote:hey Vic i just replaced the 8" mirror on my orion reflector along with new spiders i have collamated it like i always do the when i insert a 25mm and try to focus an object 1/4 mile away it will not come in to focus. im not new to reflectors owend them since i was 18 now 55 lol i need held
