Whenever I have come into large sums of money in my life, I always put half of it aside to spend on fast cars and the pursuit of loose women.
I put aside the other half to spend frivolously.
Quote:You are right, Jon. It is the closest thing to the Antares I used and almost the same weight. With diagonal and EP added plus a couple rings...it's 3.8 pounds plus a couple added. That puts it out of reach, however, for most light tripods. Outside of that, these are great.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe
Quote:To me even more problematic than the FC is the almost non-existent diffraction limited depth of focus with such scopes. We're talking microns that can be counted on our fingers and toes. Good luck with that, using a cheap focuser such as is often shipped on such OTAs.- Jim

Quote:I'm using the scope shown for my super portable option: a 60mm SV finder on a monopod. It's true that an ƒ3.75 finder will have significant field curvature but some eyepieces are helpful. Naglers and ES82s seem to have a complimentary FC that is very corrective. The 14 and 18mm ES82s are especially nice. Orthos also do well since I suspect they sweep much of the problem under the field stop. The setup in the photo gives me 9x and a TFoV of 4.66º. It is also very flexible with EP choices and filters. The setup weighs about 4.2# including the monopod. Due to hand held issues, the monopod limits me to about 18x (a 12.5 ortho) but I'm OK with that.

Quote:We did get the little ST80 for evaluation, and we like the package. It is not quite as beefy as the Antares that we had and still use overseas, but it is lighter, a little smaller, the EPs (couple of Expanse EPs) are much better, the finder scope (8x40) is much better, and the price is right (less than 180 for the OTA, rings&dovetail, 2 EPs, finder scope, and a soft pack). Focuser is tight and smooth. I will test it tomorrow but I doubt it has an issue of any mention. Last, I can get it easily and replace it easily...part of our requirement. Thanks to those who kept suggesting it.

Quote: Televue 60 maybe ?
It was a 20x power, 0.3° field of view telescope, sporting a singlet objective stopped down to 15 mm that profoundly changed our perspective on earth's place in the universe.

Quote:Anyone who has experience with TS's RFT905? In essence an ST80 on steroids: 90 mm aperture, decent 2" focuser, retractable dew shield: http://www.teleskop-express.de/shop/product_info.php/info/p5616_TS-90-500mm-R...
