Does anyone know what the power draw for scope, focuser etc. is? I see there is a generic 541 power supply similar to the one at Radio Shack. Both say the...

Hello Scott The instructions that come with the kit are very clear and easy to understand. The only downside I found was the grease however careful I was I...
I am interested in replacing the focusing rod on the back of my LX90 with the Feathertouch microfocuser by Starlight Instruments. I am hoping that this will...
Hi Gennady, Perhaps I know a part of the answer. I have never determined the exact FOV. I saw the narrowing effect of the total field by the insertion of a...

Hello, Anyone have a LX90 without UHTC? Anyone have compared a LX90 without UHTC,side-by-side with other LX90 UHTC? Yours opinions are welcome , I have...
... Radio ... enough. ... I found out from Meade that the draw is only .50A on, and .75A when slewing......so I guess the Radio Shack 22-505 converter and or...
LP filters will help but they also dim the object you're looking for but usually they darken the background more so you see an increase in contrast that ...
I have the anti-reflective coatings on my glasses and I think it works the same as eyepiece coating and transmits more light. I don't wear my glasses when ...
Paul, I have on older "classic" LX-90 without UHTC. I have never looked at it side by side with a newer LX-90 but you can't miss what you never had. The non...
I have an LX-90 without UHTC. I've never seen one with, so can't comment from with that knowledge. However, I can say that my optics are superb. There's no...
Rick, Thanks for the info. I've seen the Televue product somewhere in an advertisement. My eyesight is such that once I step away from the eyepiece, I would...
Dr. Clay, Wow, I feel lucky that I usually get about a year out of the AR coating on eyeglasses. Once the coating begins to scratch, it does degrade quickly. ...
... I find those "Meade says" numbers a little optimistic... My whimpy little ETX90 can exceed 1.0 amps when slewing. (heck, the Autostar -alone- gets up to...
... Dr. Clay did, back when UHTC was originally introduced. I think it was a pair of LX90's he used when he ran a number of precision tests to see if UHTC was...
I purchased a Astro-Tech 99% reflective diagonal (1.25") when I purchased my lx-90. I had enough experience with my old lx-10 to know that the diagonal from...
Hi Dick, Your "roughly half magnitude" seems pretty rough indeed <G>. I calculate 0.18 magnitude, from log(10)1.18 x 2.51. That is how we do it, isn't it? ...
... Could be... i was working from very foggy, three-year-old memory, vs. working it out. So 0.18 mag makes UHTC even less of a factor. (but i remember my...

Hi, Darren, I hope with all these questions you've been bouncing off the group you're writing a 'beginner's primer' ;-) ... No straight answer to that - it...
Hi All, Here is Saturn from my back garden in Dublin. This was taken with an LX90, Toucam with IR/UV filter, 2.5 Powermate and K3CCD tools, at approx 1 am on...
Well....that is how you "can" do it; observations at the "real telescope" are far better than numbers. Actually however Dennis, your .18 mag is very close to ...
