Interesting. I have 1.25" focusers on my 60mm project scopes. I didn't even think about looking for 2" alternatives. How's that for conditioning? Egad. I am pretty happy with the 24.5mm Meade Series 4000 (1.25" 68-deg AFOV) eyepiece in the 60mm f/16.7 scopes, though. ~1.6 degrees TFOV with a 1.5mm exit pupil. I can only imagine an eyepiece with twice the focal length in that scope.

Here's a shot of some 60mm tomfoolery underway...

I read the article and wish I owned a 60mm scope. Even though I live in a city, it would have been great to try as many objects possible under city pollution. At least some data could be gathered. What I have is a Z71mm WO.

...Incidentally, I also looked at a few 60mm to 70mm currently available scopes that might be nice options. The Meade NG-60 runs about $80 and looks like a modernized iteration of the classic alt-az mounted beginner's 60mm achromat...



My Meade NG60-SM 60mm achromat came in yesterday (on sale from Meade for $36.75, which includes shipping and sales tax). Haven't tested it out yet, but it's a good-looking scope. Especially like the mount and slow-motion controls.

Just go ahead and work on the list with the 71mm. The difference between a 60mm and a 71mm is not huge. Start with the bright objects to build up confidence and work your way to the fainter ones as you get more experience working under the bright sky.


Clear skies!

Or you could use a 60mm stop.

Seeing NGC7000 is all about transparency and sky darkness. It is a pretty easy object in a good 60mm from a dark site. My 80mm F5 showed it clearly from a green zone.
I could try and add to this group as my 60mm collection is not small.
