Subject: DS 80mm F11 Sent: Wednesday, October 24, 2007 08:28:52 From: Benjamin Waranowitz (firstname.lastname@example.org) I have sold my Astro-Tech AT80, 80mm achromat, F/6 as I am simplifying my life. The Meade DS with its F/11 gives far better lunar, planetary and solar views. The AT80 was nice for its niche, wide field scanning. It gave me my first view of M22, Sagittarius. I was able to easily find DSOs with it. But I now have got off ebay an old Celestron/Vixen C6 with an original wood tripod Vixen/Polaris mount. It's F/5 and it will be my scope for DSO and I expect lunar and planetary also. I plan to return the Celestron C6 SCT to my cousin when i get with him in NH this summer and thank him for its use when I had no telescope. The Meade DS 80mm F/11 achromat is a fine scope and has little chromatic abberation and very sharp images! I was able to see Saturn last winter with three or four moons with my bad eyes. When I have relocated to Scranton PA (most likely in March 2008) and settled in will be my grab-n-go scope. I got it from the Telescope Warehouse on ebay. For now its boxed for the move. I find a refractor is better than an SCT (with central obstruction) because of my eye problems. Ben
My rambling below - maybe you might want to pick something out here for your web pages. Attached pic of my DS80 from ebay's Telescope Warehouse was short one clamp, but shipped the missing part quickly. Here it is with a 2" diagonal and eyepiece. This is a sweet scope. I was going to sell it but decided to sell the Astro-Tech AT80 as this scope is better for me. The mount has nice manual slow motion control, no batteries needed. At F/11 it gives great wide angle views and also lunar and planetary images. It splits double stars. It's light to carry and intuitive. The bad: that plastic finder! He was also selling the old ETX finders that have erect images. I got two and adapted the plastic finder mount easily by whittling and it is much easier to use an erect view finder! I'll KEEP this scope, and unless I won a lottery I would not get any apochromatic refractors. I'm a reflector guy where I need aperture. I had bought one of these Meade 4500 OTA which are 114mm by 910mm f.l. and put it on my Celestron mount to see how it did. It gave a better contrast image of Jupiter thsn the Celestron C5 which is 125mm. I did sell it though as it needed a heavier mount that I didn't have. My older Kodak DX7440 and newer Z730 cameras take the same Scopetronix.com adapter. This setup works well as it is afocal, no modification to your scope is necessary. You remove your viewing eyepiece and insert the adapter with eyepiece attached to the Scopetronix. I was able to use a 9mm viewing eyepiece then replace with the setup using a 20mm eyepiece of the same type and they are parfocal. That makes the switch easier than having a big difference in focusing. I like the way they give you two extra set screws in case you lose them. I had to sypply my own hex allen wrench. I center the adapter on the eyepiece by not tightening them and rotate the assembly rapidly, and depend on my sight to note any eccentricity, then make very slight adjustments until it looks perfectly centered . One might try using a set of small twist drills as a feeler gauge for centering, I use the above method though. They worn to not overtighten. However you must have it tight enough, but not to distort the adapter. It had come off when I was too timid to overtighten. I was lucky. My camera did not fall. My mug shot. Ben
