Calsky.com website closed

Calsky.com have closed their website down after 20 years of service to the astro community. Their statement says that it was no longer financially viable.

I am sorry to see it go. Although I was an infrequent user, when I needed it I found it extremely useful.

Re: Beginners scope ?

I would add that any new telescope requires time and "practice" to get the best from it. This applies to all observers, irrespective of their age and experience. One beginners comment seen again and again is that the planets look extremely small in the telescope eyepiece , even giant Jupiter. The de...

Re: alignment difficulty

Hi Bob. It is these shaky EQ heads that make me suggest an alt-az mounting, especially for a beginner. To be honest, I think a modern driven alt-az mount has so much going for it that small equatorial heads may have had their day. That said, I have a 102mm f5 Helios refractor on an EQ1 head with a s...

Re: alignment difficulty

Hello Kay. I'll stick my neck out and suggest that you should go for a medium-sized refractor telescope on some sort of alt-azimuth mounting. I suggest a refractor because the optical system should be stable over time and not require the "constant" fettling that reflectors require to keep them in al...

Sorry, should more properly have written
"They claim that the putative "bugs" which produce phosphine (if they exist) live in the planets atmosphere, in a realm where the temperature doesn't exceed about 93C

Re: What to look at?

What you describe with your finderscope is not uncommon when you are beginning observing. You might get on better with a "zero-magnification" red-dot finder such as the Telrad ( other similar models are available at a range of prices , check astro-suppliers :) ). Many observers do mount both standar...
