I have an ASA 10N astrograph on an ASA DDM60Pro mount. I received it in this january. I use ASA's 3" wynn Corrector (x0.95) No guiding.
I've never been able to get (even Close to) perfect images with it.
I've tried with glatter laser from asa (not perfectly collimated collimator!) and TUBLUG.
Since laser isnt perfectly collimated (and I dont use ANY force when fasten it with screws) its hard to judge when laser hits middle of primarys triangle. Supposedly, thats not critical. Correct?
With Tublug I collimate primary to move triangle to tublug's center, as well as I can judge. Obviously my judgment isnt good enough cause eggs remains
I will try cats Eye later but descriptions how to use it seems to be somewhat dependent on secondary placement so that will be Another difficult excercise (I've read somewhere here on forum that ASA moves secondary down to avoid assymetric vignetting (as they should)
However it isnt clear to me if they just moved it down or moved it parrallel to seconday Surface, that makes a difference for how to use cats Eye and other Tools like sight tubes, I THINK at least.
As you notice I'm not very knowledgeable when it comes to collimation. I'm not very interested in it but now I have to. This is NOT what I wanted, I bought with a hefty premium for a newtonian precisely so I DIDNT have to figure all this out myself.
Makes me wonder about their quality Control. Also Orion optics can be a bit sloppy from Reading this forum.
The tubes where described by asa as having tested mirrors with accompanying protocol. I never got any protocol and I strongly suspect my primary is faulty.
Now my question is this, how much of these problems/thoughts do you share?
My experience is not completely negative tho, I had a focuser thrashed by not being careful when unscrewing Corrector but they sent a new one without hitting me with a charge. Kudos for that.
I have read all threads here I can find about eggs and diffraction patterns but I'd appreciete your feedback about my image as well:
is the eggs likely caused by bad collimation and is extra fiffraction spikes due to faulty primary?
Any help/thought is appreciated
