Newtonian Mirror Cells

Posted By Bill Byrd
DAR for nice cells. http://www.oneilphoto.on.ca/dar.html

Kenneth Novak used to sell curved vanes. Don't know if he still does or of anyone else selling them. Novak can be reached by phone they say but I don't have a number. Maybe someone else will post it.

New MK91 Mak-Cass has arrived

Posted By Bill Byrd
Hi Mike! Nice scope! But the flashlight is NOT gonna help your night vision any! Let us know how the scope performs once you've had a chance to try it.

What kind of light??

Posted By Bill Byrd
Gotta have very dark, clear skies to see it. I've seen it out in W TX, where it's very dark and sometimes clear.

Posted By Bill Byrd
B86 is a great one! Awesome in my 14.5" a month or so ago. Thanks for the report!

Considering paracorr for f5.6?

Posted By Bill Byrd
1. Hard to find...1.25" no longer made.
2. At f/5.6 you may not need one, esp with 1.25" EPs.
3. Yes.
4. Probably not needed with a barlow.

31mm or 26mm Nagler Type 5??????

Posted By Bill Byrd
Hi David! I'm in the same boat. My 47 year old eyes have pupils that don't open much more than 5-5.5mm. With my fast scopes, I get a big exit pupil with long focal length eyepieces. Much bigger than my eye can admit. So I'm wasting light. I've done all of the calculations and I'm going with a 26mm. Now if I had a long focus refractor, that would be another thing. But with my "fast" reflectors, I have a perfect match if I use the 26mm. I'd bet the view with the 31 will be great so use it for a while to make sure you really want to get rid of it. Even though you might lose some light, it might be worth it for those nice, wide views. Let us know how it works out.

26mm Nagler Type V

Posted By Bill Byrd
Just got mine last week and haven't had a chance to really use it yet. 1st quick looks seem pretty good. Putting the moon at the edge of the field of view last night (5" f/5 refractor) elongated the moon. About like a 35mm Panoptic does. I'll be comparing the 26mm to the 22mm as soon as I can get out under dark skies.

LXD55 10" goto meade

Posted By Bill Byrd
How steady was it? That 10" OTA looks like it would need a beefier mount to be fairly shake free when focusing, for example. How did the GOTO perform? How good were the optics?
Just curious 'cause I've been tempted by that set up also.

I like it Walt, especially since we bought my wife a Jeep Liberty last weekend.

Mirror Cells

Posted By Bill Byrd
Best I've used in that size are the DAR cells. Check with Joe O'Neil. He's great to work with.
See http://www.oneilphoto.on.ca/dar.html
The dual helical focusers are nice too.
