Finder Guide Scope

A Ponders/JJJ conversion.
Using a Phillips SPC900 and a GSO 8x50 right angle finder scope we've made a nice little guide scope to use with my new scope.
We unscrewed the right angle part, and half a roll of plumbers tape later, we achieved a snug fit. I'll be reinforcing the join with some gaff tape later. Not very elegant I know, maybe I'll buy a tube of Tarzans Grip instead and make the join permanent.
We made use of the finder scopes eye piece (the one with the cross hairs) By screwing it into my diagonal, I now have the perfect tool for aligning my optics.

Woah ! Black on black, very hard to see.

But this idea echoes the earlier thread on guidescope Focal length.

I intended to use my 80mm F5 Achro as a guide scope but beginning to wonder if I should use the 8 x 50 Finder I have coming over from Bintel shortly. Or even a modified Binoc lens assembly, 12x 50. I'll dig out my butchered Logitech Webcam and run some tests if the clouds ever give me a break.
I rather like having my little Achro as a grab and go.

Ta for the idea JJJ

There is a 'Bring & Buy' at Auckland Observatory this Sunday. Guess who is going to be there with some cash perusing the bits on sale.
Could find ANYTHING !!

On ya JJJ, it's all I use at the moment, the new OAG is sitting redundant.
Try one Brent, once you do the 80 won't get used.

I found that article and passed the link on to Ponders after we made the little guide scope.

Oh it will get used Gary, no problem.
Bought a 2" Crayford focusser for it but the tube diameter is just a wee bit too small so trying to work out a mating ring so I can attach the DSLR through it. Or might buy another web cam for planetary.

Options, always options....
