Back burner for now. But ...

We get so many requests for advice on buying 'scopes that I want to create a new webpage. If anyone would like to contribute any advice to it or recommendations on telescopes they have bought, I will include it with acknowledgements.

No financial rewards (nor for me either) but just satisfaction from helping a fellow astronomer or several.

I'll also include any book recommendations but not make any of my own.

I Bought A Telescope... and People Say It's Useless

I bought a telescope from Aldi, it's a Optus Reflector. People say it's rubbish, but when I used it, it wasn't that bad. The moon I can see pretty well. Is this telescope good as a beginner's scope?

Galaxy magnitudes

Looking at Telrad Finder charts I see that as well as magnitude they show surface brightness. Thus M31, Andromeda, has a magnitude of 4.3 and a surface brightness of 12.6 mag/sq arcmin, whilst M33, the Pinwheel, is magnitude 6.2 and surface brightness of 13.8 mag/sq arcmin.

With DSO's is the surface brightness a truer reflection of ease of viewing rather than Magnitude, or is it that plus size?
