skywatcher vs celestron

[RikM]

an avi is just a type of video file. Yes, staking the frames would give you still image but it would potentially be much sharper and with more detail than you can see in the original video. The detail is all there, just not on every frame. the software sorts through the frames and selects the sharpest bits from each frame and then combines them into one optimised image. The results can be staggering.

sounds good i will have to give it a go. do you know if my 550d would work on a 130p scope to do similar videos

Yes it should work but it won't be very easy. The focuser on the 130P isn't really up to it. It's not really strong enough for a DSLR and won't have enough inward travel to focus unless you use a barlow. The SW Deluxe 2x barlow has a thread on it so you can use a T ring to connect your camera, but it is not a very good barlow.
