Last night was a beautiful night...warm, slight breeze, no dew, no bugs, full moon. so I decided to make good on my statement to try to split Porrima again....

CJ, I split Castor the other day. What's so unusual about that? I did it at 5:00 in the afternoon; and it was quite easy with the 100mm TMB. Naturally, I used...
Despite a very bright moon I managed to "split" Porrima last night with my 100mm f/8 TMB refractor. You're quite right, Don S., it was difficult to see the...
From all of this talking about Porrima, I'm going to try this during last quarter if the weather allows me. If it's going to be a good night, I'll try with the...

Tele Vue premiered their new eyepiece at the Northeast Astronomy Forum in Suffern, NY this past weekend. A 13mm eyepiece with a 100-degree apparent field?...
I like the part about saving money by not driving for a week! What a hoot. James __________________________________________________ Do You Yahoo!? Tired of...
The out reach is on for Abbotts Mill with the Boy Scouts. We do not have to give a presentation, the Nature Center is doing that part. Observing will not start...
Good gosh biggity boo! I haven't had this good of seeing so far this year, Stars were tack sharp....at 350x! Transparency was pitch black, Dark background...
Even though its badly overexposed, the bright blob is clearly Saturn in this 20 second exposure. Titan at magnitude 8.2 sits off to the left and the somewhat...
... Mike, that 1/8-second Saturn shot appears to have captured the Cassini division, albeit faintly. Nice going! Can you talk about how you made the shots?...
Nice pictures, Michael. Might be fun to increase you focal length by using a Barlow or telecompressor in front of the camera. Another way is "eyepiece...
Both images were made at the prime focus of the telescope. The scope was a Celestron C-8 and the camera was an Olympus Evolt series E-500. The Saturn...
Good observing, C.J. With which telescope were you using 650x to split Porrima? Kent ... this ... black, ... as ... up ... by ... I ... it ... Virgo. ... the...
Although widely separated at 5-arc seconds Castor seems more challenging to split because of the overwhelming brightness of the 1.5 magnitude primary vs. the...
After the strong winds died down, I setup the 14.5" outside for some observing time tonight(work tomorrow). The winds dropped from 20+ to light and variable....
Over a month ago, My poor ETX-70 got attacked by alot of dust when my MOM!!!!! put a box of baby chickens in the same room as it. I got very angry when I saw...
CJ, Does the top of the "cut off" field of view rotate as you rotate the ep while in the focuser? Or do you see the same thing with more than one eye piece?...
I was demonstrating my new Sky Scout last night under these terribly light-poluted skies here in Greenbelt, MD, at dusk and found something odd. We were point...
Ron, I tried multiple eyepieces and it was there on every one. No, it doesn't rotate with the eyepiece either as I've tried that. I just cleaned the objective...
I think the Gremlins have goten into your scope. I do have a suggestion, though. Try removing the right angle diagonal, using only the eyepiece into the...
Oh, I just thought of something. I haven't seen an ETX 70 in quite sometime but maybe you can't remove the R.A. diagonal. It sounds like a diagonal mirror tilt...
Like said, It's an ETX-70. You can't take ANYTHING off. Which really bites. It's all stuck on. You can't take the OTA off the forks, You can't take out the...
The EXT-70 has a flipdown diagonal mirror. you could use a camera to straight thru photography. Make sure the diagonal mirror is in the 'home' position... ...
... At the risk of asking a really stupid question: Is the visible obstruction still there after the new dew shield is removed? I had an aftermarket dew ...
