Pin polarity difference Meade vs. Celestron?

My Meade car adapter cord for the LXD55/75 is center positive. I would check your new adapter for polarity with a volt-ohm meter before using.

Itz, my guess is that my Stellarvue BV1's have prisms polished to 1/4 wave at best, certainly not to the quality of my SV102ABV's Russian made objective. The BV1 also has standard coatings. I feel that using two eyes instead of one can help compensate for any defects. I just made an observing post in the Stellaruve forum here, and as you can see I was able to resolve the tiny crater Collins, 1.2 miles in diameter, with my SV102ABV and binoviewers.

This is a great image, Luca. I particularly like the detail around Hadley Rille!

Thank you Chris. I have been following your photos of Jupiter for a long time now. In fact, I owe my first sightings of Red Jr to you and your photos, literally! Jupiter has been a tough target for me visually this year and I have been lucky to get one good look at the GRS.

Peter, I own both SmartAstronomy EF eyepieces. I have a review of the 27mm on Cloudy Nights with the link still currently on the home page. I compared the EF19mm to my Meade 20mm 5K plossl and found the EF19 to be a bit superior in both image brightness and contrast. I use a pair of EF19's in my binoviewer.
