Pelican with Astrotech 66mm ED

Posted By Jeff Poplin
Nice shot, Joe! That little scope sure is sweet and such a deal.

Like you, I've experimented with my AT66 and 300D and found the field flatness lacking. Looking to try various reducers/correctors to see what works. Lousy weather has kept me from doing much lately. Bermuda High spells soggy summer weather for mid-Atlantic states.

M22 Great Sagittarius Cluster

Posted By Jeff Poplin
Wow, I =do= remember stars and globs and clear nights. Your picture makes me long all the more for some dark nights. A club member gave an interesting program on the globs in the Sagittarius area, keying off M22. There are several, in decreasing sizes just a few, short hops away. I love this area of the sky.

Thanks for a wonderful shot!

Eagle, Swan and the Big M24 Star Cloud

Very nice wide field views, Ivan. Amazing, given the humid conditions you had.

Friday night was drier, but not as transparent. At least the T-storms stayed away.

Keep up the good work,
Jeff

Impressive, Ivan.

I, too, can't wait till fall to see your deeper shots! (and some clearer skies...)
Thanks!

This guy has a nice RFT design. I like the way he solved the counterweight problem!

Also, the Nasmyth focus is where a diagonal is placed in a Cassegrain system to bring the focal point out one of the declination bearings instead of being behind the primary.

Posted By Jeff Poplin
Wow!
From the looks of Beagle, I think Victoria is going to blow us away!

Go, Opportunity!
Go, Spirit!

(I knew something didn't seem right when I saw STS-114 on the link...)

Great shots, anyway! Thanks for the link(s).

The MSFC folks have recorded 7 possible impacts in about 30 hours of observing.
