Excellent, beautiful view. Thanks for taking the three years to accomplish it -- and for sharing.

Lunar processing help(?)

Posted By Bob Polcyn
Hi James --

It's a beautiful image and thanks for posting it. I had a difficult time orienting to it however. Using Photoshop it took right/left reversal (flip horozontal in PS) and about a 40° clockwise rotation to match a typical inverted scope view. With those manipulations the match is very good with a 19 day old moon image in the Legault and Brunier atlas. Then I could ealily identify Mare Nectaris, Mare Tranquilitas, Craters Theophilus, Madler and more.
I'm a relative nebie to lunar observation but wouldn't it be great to have a standardized approach to image orientation?

8.5" F/12.5 Refractor

Hi Kieth --

The design is excellent -- makes one rethink big refractors.
What's your thinking about equatorial vs alt/az mounts for a scope like this?
Thanks for sharing.

Nikon 20x120's

Posted By Bob Polcyn
Well, I've bought a used pair of Nikon 20x120's mounted to a very sturdy Manfrotto tripod. It's going to be a love/hate relationship, worth the clumsiness of the set-up based on really spectacular views. The 20x120's were designed for surveilance and open water fishing boats -- the owner's manual essentially says so. The yoke mount design says it all.
It's going to take a while to build, but I have some ideas for a different mount which should make it an all sky viewing system. If/when successful, I'll report. Thanks all for comments.

Mercury as Autumn Morning Star

Thanks, Curt -- nicely done and useful. I'll match the graphic with my atlases to give me a better sense for finding it.

Moon is too bright

Hi Ken -- I haven't done it in a while but I've used a binoviewer (an Olympus microscope head) with my Zeiss 63mm/840mm and found the combination very comfortable to use -- no filter.

Use of a doubler with binoculars

Posted By Bob Polcyn
Follow up: There's not a lot of info about the Swarovski doubler but one website mentions unscrewing the eyepiece on the binocular (Swarovski of course) and replacing it with the doubler. So, this is a dead end.
The question remains though -- is there a practical way of increasing the magnification of fixed mag binoculars?

I have found a way to bring near focus of binoculars closer for terrestrial viewing. I just look thru the lower part of my bifocals -- works very well.

A neglected jewel in Orion

Hi Inge

IC 443 is just less than 3° northwest of NGC 2174. Is it as easy to observe? -- and does an O-III help with it?

Thanks for the idea and the list, Inge. I too will give it a shot.
