Hi Jack, I looked at the images on your site and I can really see the bluish color in the photos - however I don't see anything like that in the TAL. The moon...

Given the advantages off off-axis newtonian telescopes I'm surprised that there is not more discussion about them. They seem to offer the optics comparable to...

Jim, To answer your question, the link I sent is for Rubylith RM3. I also bought some from Scopestuff. The stuff from Misterart seems to be identical. Phil P. ...

Thursday my new 12 inch XT Intelliscope from Orion showed up. Finished assembling it this morning and spent three hours this afternoon collimating it. Looks...
