Ex+ non ED or bargain ED

Posted By Walter Hamler
Chris, I have dealt with KEH for years and what they call "bargain" most others try to pass as excellent+++ to mint, so they are very conservative in their ratings. Go with the ED, especially for astro work, as they are sharper wide open.

Re: good planetary eyepiece

Posted By Walter Hamler
Well, I guess my 60 yr old eyes must be failing me because I have tried several of the eyepieces listed and own or have owned several others. The one that I always go back to as the very best image is a 15mm Panoptic. I find it even better barlowed than going to an 8mm Televue plossl. This is with 8 and 10" f/6 newts.

How does one treat a cardboard tube?

Posted By Walter Hamler
Remove any wax or plastic film that may be coating inside or out. Coat in and out with 2 liberal coats of polyurethane, either satin or gloss. When completely dry, sand lightly and then coat the outside with fiberglass resin. Apply two coats with sanding between each. Wet sand the final coat with 400 wet/dry sandpaper. Prime with a good auto primer then pain your choice of color. Should make a great tube. Cover the inside with flocking paper. If you can order from the states go to http://www.mcmaster.com and check under fabrics. The black velvet without the adhesive backing is great stuff and cheap!! Use a good quality white glue to glue to the inside.
Probably won't even need baffles after using that stuff.

Re: 20x80 binocs or 7x50 or what???

I use a pair of the Oberwerk 15x70's and love them. The price is right also. Big Binoculars.com Check the Astromart list of advertisers.

Go to http://www.scopetronix.com/ They sell adapters for all types of digital cameras. I just jumped into that arena myself and it is fun.

Orion 100 f/6

Posted By Walter Hamler
I'm sorta curious myself, but primarily as an astrocamera and as a long fast "cheap" terrestrial telephoto lens.

Another stab at M31

Posted By Walter Hamler
Paul, are you using a guidescope to monitor guiding or just running the AP mount on it's own tracking. My mount is just not capable of doing that, so I am going to have to get a small guidescope if I wanted to do something like that with the 4500. I tried to find M-13 last night in the viewfinder but it was too dim and it had started to haze up a little.I did discover last night when I got the shot of E Lyra that if I focused the telescope first with the eyepiece, then attached the eyepiece to the camera and back on the scope, the focus remained sharp.

Coronado first light!!!

Posted By Walter Hamler
Paul, Saturday PM I was volunteering at the local science center here in Orlando. They have a 10" f/9 refractor on a huge Byers mount, and they had their Daystar Ha filter attached. I think I saw the same prominence as you have photographed. That sure is an awsumb sight through those type scope/filter combo's!

Who Made This Telescope

Posted By Walter Hamler
It's one of those "mass produced" versions that had lots of different names. Kowa, Mayflower, Soliger, maybe even Tasco. I remember seeing them in the department stores back in the mid 80's or so. What kind of star images do you get out of it??
