A new view of the moon

Recording video from the DSLR is by no means new technology. Indeed most intermediate and top end cameras now employ full HD recording. Though my poor old 40D does not have such a luxurious feature. Many full moons ago I owned a 300D and I found a programme that allowed video recording, provided you do a hack to the firmware, Having read several posts from disgruntled owners I thought better of it and stuck to the Phillips TOUcam the original egg shaped model I might add. (For sale if anyone wants it) for my lunar and planetary fun. Used with my Orion Optics 10" reflector then. Having moved onto to the refractor and the wonderful wield field images it produces the moon soon became an annoyance rather than the orb of beauty it is. So recently I was trawling the popular social network site and saw an advert to cheap DSLR's a few clicks and some disappointment later I saw an advert for LIVE VIEW recording. No firmware hacks just a simple programme to install and connect to the DSLR. To test it I had set the camera up on a tripod facing outside. Open live view and your pic appears on the screen. Leaving the camera lens on auto focus allows you to tweak it using the controls on the laptop. Pressed record and bingo a very high quality recording. This is the part that really got me though!!!. I zoomed the lens onto a flower and hit the 5x magnifcation button on the programme to adjust the focus once happy I pressed record again leaving it set to zoom. I played back the video expecting to see the full frame but no I had an amazing video form 5x mag from the live view. The recording was about 20fps and incredible. You would think I worked for the company or getting a commission for the programme sales by now. But sadly no as it is free. I immediatly thought that through my modest 90mm refractor and additional help in magnification would be a bonus. A break in the clouds a few nights ago allowed me to test. Here are the results. Camera set to manual 200iso and 1/160th sec exposure. I have a 2" barlow for the close ups. Each video was about a minute and Registax processed around a thousand frames each time. Nothing more added than a wavelet sharpen. Link to the programme can be found here.  http://sourceforge.net/projects/eos-movrec/

Brilliant! Malc.
Beats the webcam images.
Will have to try out the video on my 500D.
