I have been looking at the tabletop 130mm Dobsonian Reflectors reviewed in the astronomy magazines.
These seem ideal for me having a good light grasp and being manageable in size. However the problem I can see is collimating the mirrors if they go out of alignment. I am pretty useless at anything practical, as can been seen from my previous posts regarding trying to line up the finder scope with my 90 mm refractor ( f/10 ), which I never successfully achieved. Any advice or suggestions would be gratefully received.

Thanks
Chris P

Hi Chris,
The other problem might be finding anything.

Tabletop 80mm f/5 refractor?

Regards,
David

The SKYWATCHER Heritage 130P gets a good review in the current "Astronomy Now" magazine.

Hi Chris,

My first telescope was a 40mm refractor (of sorts) from Boots which had a tabletop tripod and simple push/pull focuser! I don't think it was even designed as an astronomical telescope since the image was the right way up. I ended up balancing it on two two tables, one on top of the other in order to get it into a manageable position. Crude by any standards but I did get my first glimpse of the Moon and the satellites of Jupiter with it.

That was back in the early 80s' when I was 11/12. Today the choice is somewhat wider with dobsonians in the 6"/8" aperture bracket offering the best around value. It all depends on budget of course but a 6"/8" telescope on a usable mount for £179/£279 is superb for beginners and they even come with eyepieces!
