All Sky Mirror

Posted By Andy Khula

Noticed the picture today on spaceweather.com was taken with an all-sky mirror.
Does anyone else use one of these. What size mirror. Seems that a stainless steel mirror would be good if a heater was put under it. Acrylic would be cheaper. I've tried the baby moon hubcap method but couldn't find one bigger than about 10 inches and the surface quality was very poor for this application.

An Oldie rides again

Posted By Andy Khula

This one has been percolating for a while and was out a few nights ago(the bugs are the worst lately). Been workin' on it for a few years off n' on. It's an old 12.5" f/8 Coulter (1971) mirror on a modified Meade DS16 mount on a 10" dia AP standard pier.
The pier has a special removable setup (I call 'em "slippers") for the 10" tires.
Probably will put a ToUcam on it once in a while to keep me off a tall ladder.

Anybody received their Jan-Feb 2010 Astronomy Technology Today mag yet?
Got an email Jan 15 from them saying... you will receive your issue two to three weeks later than normal.
I miss it like a dog without a bone.

No enforcement it seems

Posted By Andy Khula

TERMS OF SERVICE
15. PROHIBITIONS.
(h) Any item/s that are placed on any other site for sale at the same time it is offered on AstroMartâ„¢.

Seems that this clause in the tos is routinely trampled on.
cn runs the same ads, same item, same pics.
Best advice is always buy thru Astromart.
I bought an item on cn and got lied to and cheated by a respected
cn user. Never got all my $ back. He's here on Amart too but I can't rate him.
Never again. Got what I deserved.

Home Built Solar Scope

Posted By Andy Khula

This seems like the correct forum to ask.
Does anyone here know if the solar Ha scope described
on Dave Groski's Solar Page has been built by an
Astromart member?
The correct filters are still available from the source
mentioned on his webpage.

Re: Canon EOS Rebel XS and suggested modification

Posted By Andy Khula

Well you can use it for astrophotography right now but red sensitivity can be greatly improved by getting the camera modified. Hap Griffin modified my Canon 20d using his option 3B.
Never regretted it and you'll get the pics you want having it done. There are others that can do the mod or do it yourself but Hap has done a lot of mods and I haven't heard any complaints.

Hap is an Astromart sponsor http://www.hapg.org/
