Hi Guys
Thanks for that. I find that the Vixen 4" can split Antares relatively easily visually, whenever the seeing is above average and Antares is anywhere near the zenith. A 5mm eyepiece (x180) is usually sufficient although when the seeing allows, a x2 barlow giving x360 makes the split even wider. I have been trying to split Antares for 2 to 3 years with my ST7 ccd camera but failed. The LPI seems to do a better job, I only had to experiment for a few sessions.
I admire your efforts Andrew, using a dob and manual eyepiece projection, as I need the full armoury of an equatorial mount with motor drives to attempt this!
Cheers
Dennis
