EP Cleaning Question

Posted By Bernard Kean

Hi David
As I understand it from Al Nagler, most modern coatings now days are pretty durable and he says about any NON-ammoniated glass cleaner will work. Just don't flood it on so it doesn't creep into the eyepiece and produce moisture inside. I dust the lens first and use a cleaner from my eye doctor and it works great, then if there are any small residue spots I fog the lens over hot water (breath will work if careful) and lightly wipe. I might use a bit of alcohol for stubborn eyelash marks but I avoid it unless necessary then clean as usual. There are many trains of thought on this so there is no one way that is best. The main thing is, once you find a method that works for you, do it the same every time. The Zeiss Wipes work great if you crumple them up to soften them first and let a bit of the liquid evaporate before using.
Hope this helps

Collimation Help Request - Now with video on later post!

Posted By Bernard Kean

Dannon
Exactly what do you mean by "went all out of whack". Put the laser in and set the scope at about 45* and center the beam in the donut then raise and lower the scope and note what the beam does. As others have pointed out, it could be a cell or secondary problem or some truss type scopes might have a slight sag from the weight of the UTA. I usually collimate with the scope at a 60* angle which is where most of my viewing is at. You might also snug up every screw and nut in the entire scope before spending too much time trouble shooting.
Just a few more ideas to check out.

Looking for air filter ideas

Posted By Bernard Kean

Hi Doug
The thin foam furnace filters should work if you use 2 or 3 layers stacked and cut round to fit in the hole snug. You might also install a thin screen or several wires between the fan and mirror box so they don't contact the fan blades. One furnace filter should be enough to make many plenty of small rounds ones. Can be had at Home Depot or Lowes or anyplace with replacement furnace filters.
Hope this helps

8x50 Finder - A little help please

Posted By Bernard Kean

Hi Dave
You might check out the Orion 9x50 RACI, they should be a good bit cheaper than the others but the quality I doubt is as good. But then its only a finder. I have one and while it works fine without glasses, I did try it with my glasses up against the eyepiece and it does work but I cannot see the entire FOV, maybe 4* to 4.5*.

13mm Nagler T6 Question

Posted By Bernard Kean

Alan,
I agree with Clyde, no issues like that in my TV101 and SM11 f/5.4, in fact it' one of my favorite eyepieces.

We're down a hill from neighbor's front porch ligh

Posted By Bernard Kean

Cecil
A polite introduction from the new neighbor might be a good start then over the next few weeks try to get to know them. In a few weeks time, find the right time to ask them over for a few looks in your telescope but politely ask them to turn off the porch light on the way over. During the evening mention that you have noticed that they leave the porch light on and ask if they would mind turning it off on the evenings you plan to be out.
Just a thought

Nag 26 or Pan 35

Posted By Bernard Kean

Gerry
I've owned both and used them in a TV101 f/5.4 and a SM11" f/5.47 and I much prefered the 26mmT5 over the 35mmPan. Between the long eye relief and large exit pupil in the TV101, I had a difficult time with eye placement using the 35mmPan. The 26mm gave up a bit of TFOV but but to my eyes it was sharper and darker and a more comfortable eyepiece to use. Another eyepiece that is quickly gaining favor with me is the 20mmT5, this is one very nice eyepiece.
Just my $.02

Mount for a 4" Refractor..Please Help

Posted By Bernard Kean

Steve
The GEM that the other Steve suggested is one way to do it, check this out Classified #378488, however another way is to get and Alt-Az type mount. The Helix Alt-Az mount head on a used medium or heavy duty photo tripod would also work. The Televue Panoramic or Gibraltar mount is another excellent but a bit more expensive route. There are many Mfg's and ways to do this type mount.
Hope this helps
