... Thanks for the very interesting history and explanation about the Orthoscopic eyepieces. Makes me want to think about trying a couple for planetary...

... Frank, I took a look through a Orion 12" Intelliscope Dob with a 5mm Status EP last week at the TSSP09, Saturn and globulars, and the view was fantastic....
The further adventures of rehabbing my 8" DSE...in the course of attempting to collimate, I have located screws on the secondary mirror, on the side closer to...

Hi Just find your self a nice set of inexpensive SAE allen wrenches at your friendly neighborhood Wal-mart, K-mart etc. Garry Mtn Home, Id Xt10i Sky watcher...
... Yeah, just did, from Advance Auto Parts. Less than $10 & got one to fit. I'll do the collimation this week & report results after the next time I'm out...

I already had forwarded to me last week that same email Geoff mentions --at least my friend sent it to me to check it out before breathlessly forwarding it to...
That little tidbit has been floating around the Internet since Mars did make a close approach six or seven years ago. The problem (or one of its problems) was...

Hello, new mwmber here. I've just placed an order for 100mm ed refractor with a 9.0 focal ratio. Any suggestions on EP's? It comes with a 25mm and 12mm. Thanks...

Thanks, Geoff, I found an index page with Anaheim centered, close enough for me, similar to the one you sent me a few months ago. Here is the issue/question,...
The f/9 focal ratio will be more forgiving on eyepieces than scopes with faster focal ratios so you do not need to break the bank on Naglers. You should seek...
