Vixen ED115S or quality 4" refractor?

Posted By Jerry Brown

Vixen ED glass is great but the TAk flourite elements are amazing.Anyone that looked through my FS78 always said wow. Me included.

My Vixen ED103S focuser sagged and the the focuser on my Taks did not.

Because of these two facts, I would guess that the only time the Vixen 115 would be superior to a FS102 would be at very high magnification.

That is amazing work. I thought I was getting good at imaging the moon until I saw your image. I hope you try to image the LCROSS impact.

You might point it at Sadr. It is incredibly easy to find and there is a great deal of nebulosity and a beautiful open cluster in there.

I have had no problems with using a laptop in the cold. I do throw an insulating cover over it when I close it up and monitor it remotely.
