Sirius split.
Last night I split Sirius. I've been trying for about three summers and was starting to think that I didn't have enough aperture/magnification. So I was wondering if anyone else has used similar equipment to split it or was this a bit of good luck?
I did it using a 12" Dob , a 5mm Pentax XW giving 300x magnification and a perfect ( by suburban standards ) night at about 10:30 when Sirius was about as high as it gets and perfect collimation and a slightly dirty primary mirror. Every now and then Sirius became nice and sharp and Sirius B showed itself. Very very exciting. I always thought that you need much more than 300x magnification. Now I think it has a lot more to do with the collimation and the seeing.
