I have a 80f5 home made scope (objective dublet bought from surplusshed)and made a few astrophotos with it. I wander about buying a standard 80f5 from Orion,...
Hi Paulo - Pretty cold this year in Porto Alegre? Your 80mm homemade scope may not be much better optically than one that Orion sells. I don't remember seeing...
... because they use a larger scope on a good mount to do the tracking and the smaller 80f5 rides piggyback with a camera. That sounds right up my alley. <G> I...
Hi Jim Yes, we have a pretty cold weather in our light polluted Porto Alegre now. My 80f5 uses a coated achromatic dublet. His worse point is the field...
Many thanks for the link, Leo. I'm well impressed by the Horsehead taken with Orion 80f5. Which mount did you use to get it? Some ideas about focal reducers...
Hi Paulo - Very nice images. I can see you have really thought about exposure times! The Orion ST will definitely focus more of the field for you. But I would...
Paulo, I've been following this thread right from the beginning, but I was in a hurry to meet some deadlines for a client so I had no time to jump in. I just...
Hi Jim The lenses were not home made, just the scope. By the way, thanks for the indications. You, your wife, as well as other friends are welcome to south of...
Hi Carlos In fact, the achromat doublet I received from Surplusshed was not well assembled and I had an ugly spherical aberration. After I re- arranged the...
Hi, I'm new here and am interested in obtaining a ST80 for use as a RFT and as a sunspot observing telescope. Regarding the latter, is the ST80 a decent scope...
Hi Clay, welcome aboard. On Astromart I picked up a solar filter made of Baader film for $20, for an 80mm scope and it was the best view I ever had of the sun ...
I never tested mine at high powers since I have larger scopes for that. In general I think 100x might be the general consensus. Do a Google search "orion st80...
Hi... I'm not an expert in imaging with my ST-80 (or my 10" dob, for that matter), but it is quite clear the general guideline of about 50 power per inch of...
... Clay, I have had a Celestron 80WV for a number of years now and I find it very suitable for the roles you mention. As a RFT it works great and gives a very...
... and as a sunspot observing telescope. You've already received some good advice, I'll try and add to that. I use my wife's Orion ST-80 for sunspots using a...
It works great for this. I've used both an Orion glass filter and a Baader film filter. See my picture (handheld digital camera to eyepiece) in the AstroPhotos...
Actually, Daniel, I agree that 150x is too much with my ST80... for reasons I didn't pay attention to at the time I posted that, I have long since found that...
... Maximum practical power is quite a bit "less" than the "50 per inch" usually stated. Major reason is that short focal length refractors (unless using ED...
Mike in one of your photo captions you say you couldn't find suitably sized nylon washers. You might try cutting your own out of plastic milk jugs. A lot of...
It's been years since I posted my last message, but I've watched the messages from time to time. I have a Sky Watcher 80mm f/5 on a EQ-1 mount. I've completed...
... Did the elements stay stuck together or did they come apart when you disassembled the cell? All the Synta made 80f5's I have pulled apart the lenses stayed...
Phil, The elements came apart. In fact, the front element came out first, and I initially gave up on even getting the second element out of the cell! I finally...
I just joined and have the OTHER, non-Chinese 80mm F5 refractor, the Vixen A80SSWT. It is a neat little instrument with some different features than the Synta...
Hello, Rich - Oh, the Vixen - I've admired their products for years. As I understand it, they're definitely a higher class product than Synta's. Having owned...
