Hi Everyone, I just heard from Christine at Astro-Physics that the phone lines and internet access are down at Astro-Physics right now. Apparently an outdoor...
I'm going to be doing some serious thinking about purchasing a 900 QMD mount from a friend. It was a few months-before-the-QMD mount that was later upgraded...
Greg, I would think the issue being more that back in 1995 one did not have the opportunity to stack 1000 or so images taken as such a fast speed. Much less...
... I dont think this is available for the 900QMD. Is this part of the DEC axis upgrade only? What are you going to do for a pier? I bought a 54" pier from AP ...
The QMD mount is an excellent mount. Mine is used on the 54" pier with an AP 155 EDFS and is very accurate and stable. It guides very well using an ST4 and...
If i read well the comments around msg 15145 and 5253, it seems indeed that a very good F14 Mak 10" would perform like a very good 9" refractor. Logically, the...
Thank you, do you have the default az and altitude hardware or did you upgrade, and have you ever noticed stepper vibration while imaging or observing at high...
Well I was perhaps a bit touchy for which I apologize. People are allowed to wax enthusiastic about their scopes and their choices. Of course an ideal scope...
... Greg, This was one of the most thoughtful and well stated posts I have read for some time. I found nothing to disagree with. In fact, your comment about...
I have four AP mounts: 400qmd, 900qmd, 900gto and a 1200gto. The 900gto is still in the box (I haven't had time to set it up since I got it a month ago). The...
Damiens Saturn Image looks like a HST image!...? :-o http://www.theplanets.cjb.net/ Mike ... low ... on ... settle ... to ... <kurt_friedrich@y...> ... good...
... Whats the Peach Formula? Putting Celestron telescopes on Losmandy mounts and producing the best amateur planetary work in the world, under typically...
WOW! It DOES look like an HST image! And, yes, successful planetary imaging is as much processing as anything else. Mind you...garbage in garbage out still...
I echo jjk's comments---it is light, simple to use, and elegant. With the Argo Navis, in my view you essentially have a manually-operated goto. I also have...
The difference is that if you take an amateur image and enlarge it, say, 50x, you'll begin to get blown up pixels. If you enlarge an HST image 50x you'll get...
A year or so ago I called attention to the appearance of a rift in Jupiter's NEB that was obvious in the C14 but was extremely easy to overlook in some...
I want to thank folks for their insights into the QMD and I'd love to hear more, particularly about the alt-az configuration. From what I have seen in pics...
I have a 900QMD and concur with the prior opinions. It has no upgrades, works fine as is (AP155EDF/ED80). No noise or vibrations. NGC-MAX for "push-to". Very...
Greg, The azimuth adjustment is very convenient, adjust both knobs at the same time, snug them up when you're where you want to be and you're locked. I...
... His entire Mars '05 sequence is a tour de force.. http://www.damianpeach.com/mars05.htm Remember to click on the images for the superhero versions. Look at...
Keep in mind that for owners of large dobs such as Starmaster and Obsession, the Argo Navis is a necessity and I believe is standard equipment with the...
My observing buddy uses AN and a 15" obsession and I agree that the major problems with AN have been on GEMs. But these were not "major problems with Argo...
