I pulled the goto dob out while deep sky imaging. I thought I would give the video on the A7s a test run.
I had to use a 5x powermate and a 2x barlow to bring the image scale up due to the a7s having a full frame sensor.
these were captured at 100fps. probably equal in quality to what I've achieved on the old 600d but I've never got the knack of planetary processing.
I also have a feeling that there is some extra noise introduced while the memory card was buffering, the card I think is rated to 45mb/s and I think the a7s records at 50mb/s.
thanks for looking.
PIPP to crop and centre (and convert video format!), registax 6, astra image and cs6. the widefield was about the standard size off the camera but was reinvented in photoshop.
