I don't have a Newt but I have a couple of scopes (Cassegrains) which have open primary mirrors. My question is how often do you clean your mirrors? After 18...
About once a year---I rinse with luke warm tap water and blt (never rub) to eliminate water spots. The dirtier the mirror the harder it is to clean it. ...

Thanks to all. I am encouraged to hear you do clean the mirrors annually or so. Yes, I have lots of pollen in the air and probably some on the mirror. What...
I have a 10" Newtonian and the following youtube procedure works for me. Note: I tried a hand dish washing liquid that was more viscous and the liquid seemed...

Thanks Drew Aluminizing movie also and more Some animations are over 100MB downloads, so be aware. http://www.astro.caltech.edu/palomar/animations/ jimmy...
Typically Newts tube lengths are very close to the focal length. Classic f/6 ones are usually exactly that-(I have the 10 f/6 and the tube length is 60")-it...
Hi All, Just joined last week. I'm getting back into the hobby after an absence. I have an old Celestron C4.5 reflector and it's been pretty good to me. ...

Hi Ben, Like you I moved from a smaller Newt to an 8", a Celestron C8-N with a Moonlite Crayford. I tried it on my CG-5 and it nearly overwhelmed it, terrible...
Ben, I would agree with what Mick has written - it has a lot to do with personal preference. I started off with a 6" reflector on a GEM because back then...
HI All: I want to rebuild my eight inch dob using a new length of sono tube. Any directions to web sites showing dob mount construction that I could do with my...

Hi Frank, Well that may cause me to do some re-thinking. I had been looking at the C8-N (been real happy with my C4.5). One of the local shops has the C8-N...
Hi Mick, Thank you very much for your thoughts. You are correct, I need to decide what fits my world the best. I am hoping to get to try out both type of...
Hi Ben, I've been out of town, sorry I could not get back to you sooner. There have been three iterations of the CG-5, the latest apparently has tubular steel...

Hello Richie: I noticed that the 5" reflector has been "Discontinued" by Celestron, But it should be easy enough to spot the Moon with it. once you have your...

Your 1 and 2 are both possible. Additional possibilities are 3. Low quality telescope 4. Collimation needed 5. Seeing conditions (steadiness of the air)...
Richie, your 5" scope should handle 150x. I am not familiar with the quality or build of the powerseeker, but a 5" scope at a maximum of 50x to 60x per inch of...
Richie, The addition of your Barlow is the cause that you cannot reach focus. The solution might be as simple as inserting a diagonal between your Barlow and...
Hi Richie: I am glad you found Saturn: Before going out to observe with your scope, try keeping it under a shed or in the garage about 30 minutes before...
yes W. i can fully adjust the focuser in / out, but object is not clear.... although the planet was clear though the 20mm eyepeice, but looks a very small...
