I sold my old Dynamax 8 earlier this year, finally, after a quarter century! For me, it was a great scope. Amazingly, you WILL find a handful of people who can tell you the optics are not too bad. I'm one of them. I had it checked out against the optics of other scopes from that era and was surprised to find it fairly comparable. Then I had the opportunity to meet up with other DX8 users whose scopes had horrific optics. That was when I first learned of Criterion's quality control issues. I had many a good night with my old DX8. But I stopped missing it as soon as I got my "new" Meade 10" LX200 Classic under dark skies. I have never before been able to literally fill the field of view in a 26mm piece with M42. Sakes alive, I about fell over! And yes, the optics are far superior, not to mention the overall improvement in aperture.

I'm new to CloudyNights, but a long time astronomy guy, and I just happened to come into possession of a very good condition Dynomax 6" SCT! It was completely out of alignment, but after a few hours last night, it went from "unuseable" to "reasonably good". I figure it's about 70% collimated now, and I'll continue to work it...
HOWEVER, the one thing it was missing was the owners manual! If you would be so kind, I would like to take you up on your offer of a copy of your owners manual - I can handle it in virtually any form you've got (electronic or paper) so let me know what works for you and I can let you know where to send it.

Actually, I've been pounding the internet pretty hard the last 24 hrs, and interestingly, the vitriole around Dynamax seems to be almost exclusively aimed at the 8" - the specific references to the 6" are almost all pretty good - and this one, despite the lack of care, seems to be both configurable and have no obvious defects (it DOES have very jeweled motions in the controls); I also know how difficult collimation of an SCT can be (very few folks actually DO it) so I'm not surprised that if a number of these came from the factory out of alignment, there wouldn't be much mercy for them... This one does appear to be in excellent condition, but the last 20% of collimation will, as they say, tell the tale...

Remarkable - I was given this scope by a friend who recovered it from the LAND FILL. I suppose "one man's garbage is another man's fully functional SCT!"

Man you LUCKED OUT with that DX6! I can't believe someone would ditch it in a landfill! Just heartbreaking! They could've donated it to a school or something. What a find!
I'm glad the collimation yielded good results for you. My old DX8 was a beautiful performer, so I consider myself one of the few lucky people in the Dynamax 8 world.

Just a question...did anyone actually think the Dynamax SCTs were good enough to keep? I've used two, and they had a poorer star test than a cheap christmas trash 50mm refractor.
Mine has a somewhat poor star test, but 8" of scope is 8" of scope, and the aperture is enough to make me prefer it over my other scopes (one of which is a 6" newtonian with optics beyond my ability to find fault with.) It will split the two doubles of Epsilon Lyrae, slightly messily, when properly cooled and collimated. The benefit of 8" is, of course, not the star splitting ability but the bright images.

If you guys are interested, I just posted a picture of the landfill rescue DX6 on the next thread ("6 inch B&L...") - check it out!

Couple questions for you:
- have you ever had to collimate your DX8?
- what kind of a mount do you have? Criterion or other?

I am guessing that the Dynamax's quality varied all over the place near the end. If you got a good one, you're good, but those who got bad ones were really unlucky.

If you're interested, please email me or give ma shout here. It's nothing great, being mostly scanned images of the pages that were made quite some time ago. I will try to find a place here at CN where I can upload this folder of files (6mb original total size or 1.13mb re-sized).
Any chance you can re-scan this or send out the original size files? I just can't quite read these.

Count me in, too - if you make any mid res/ high res copies, I'd love a set.
