I don't think the seeing was that good when I tried mine, I couldn't come to focus properly with the barlow, the seeing just couldn't support it. So I stuck with prime @ 1250mm.

Hi Mike
The seeing was reasonable at prime focus and using the TeleVue x2.5 allowing the Meade LPI software stack several images to improve the result. At x5 I managed to grab over 250 individual images before the seeing really turned bad and less that 10 were any good. These would not stack as each one was quite "different" due the image shearing from frame to frame with the seeing.
The Vixen 4" is a very forgiving 'scope to image with due to its short focal length (918mm). I acquired the images between 8:30 and 9:30am.
Cheers
Dennis
