In India, jupiter is still "way up there". Seeing isnt that gr8. Once i couldnt go beyond 50X on a 5"f/8. Temeratures regularly go beyond 110*. Once, i was...

From: "Paul Gustafson" <laservet@...> ... Here's a web site that has a Baader OIII transmission curve: http://www.alpineastro.com/filters/filters.htm#O-III...
... The curve on the alpineastro site obviously comes from Baader's website: http://www.baader- planetarium.de/zubehoer/okularseitiges_zubeh/farbfilter.htm#o3 ...

Which eyepieces, without breaking the bank, would you recommend for use with a -10 inch dobsonian, -f/4.5 -1140 focal length to get the most out of it? Which...

Well put, Ed (just catching up after week in Rockies). I have an 8-inch SCT AND a 12.5-inch Truss DOB, AND a Stellervue short-tube 80mm refractor for wildlife...

Hi Erik I was in Belgium for 6 months as an Erasmus student in 1993, in Ghent. I loved it. It was really nice and there's a special room for Belgium, Ghent and...
The Celestron O III looks very similar (but cheaper) to the Baader filter. Does anyone know for certain if it is the same or just same filter mount and...
On Cape Cod, 41-44-04 N., 70-10-31 W., I concur that seeing to observe Jupiter has been difficult for a month now, and maybe it's time to say goodbye to our...
