Group, We were out this morning to see the Shuttle re-enter, heard the sonic boom here in Tahoe but the over cast prevented any visual. A friend caught this...

Hi all, I've noticed that there is no forum on the web about equatorial platforms and other poncet tables. I've therefore decided to create one. All platform...
Hi Futtrich, I have no idea about it's motion in the photo. My friend that took the picture said he was looking south and it was about 38 degrees up. That...
I checked the web for photos of previous (successful) reentries. On previous reentries, the shuttle was leaving a semi-persistent trail by the time it got to...
Hi! Where did you get the axiom 40 for $150? Did you like it? Is it really the smae as the UO MK 40 Thank you. TomL ... are ... Slightly ... too ... scope. ......
Hi Tom I got the 40mm Axiom for $150 at Eagle Optics about a year ago. Seems like they were clearing out their Celestron stuff at that time. I can not bring up...
Bob Thank you for info on Axiom - I was also condsidering 36 Siebert Observatory or UO 40MK70. Siebert sounds like a good choice also - The more we discuss it...
Tom, as long as you keep putting Erfle type eyepieces in that fast scope you are not going to get the edge sharpness that you desire, regardless of who makes...
Thanks for response... I was assured by UO that the UO 16mm Super Erfle is for a fast scope. I'm still pretty new and learning as I go. Well, I hope it is OK...
In the 12-20mm range it is hard to beat the 15mm Panoptic. Do not know the current price, but it is much less than the 27/35mm Panoptics and Naglers etc. I...
Tom, I am in the same boat as you. I just took delivery of an 15" F5 Discovery scope. All of the eyepieces that I posses are about 20 years old. I just...
Many people with fast scopes use the Pentax XL's. I have the 10.5mm, 14mm, and 40mm versions, and they are all excellent on my f5 10" dob, with sharp views to...

Attaching black velvet to the various small metal and other odd shaped parts of the scope that can reflect into the light path might be a little more ...
Don, Can you really _not_ think of a reason not to use black velvet or are you just trying to be funny? There's no reason to respond that way to someone's...
My novice attempts at starhopping with the Telrad on my 12.5" Dob have mixed results. In my viewing area (semi-rural neighborhood w/some outside lights...
I thought Don's reply was lightly humorous, and definitely harmless. I guess that means that there are at least two insensitive,cruel meanies on this board. ...
the telrad is basically a window, no reversal of image in any axis. this makes it very useful with a Right Angle Correct Image (RACI) finder. Go for it! jtm ...
... Some have observed velvet dropping little particles on their optics. For a good blackening material avaiable today, check out FPI-Protostar's flocked...
I meant no offence. It seemed interesting that comparison of a really black surface is to black velvet. After some reflection...If I was trying to be funny, I...
