Hey Alex,
Thanks heaps for posting this.
As an example of what went wrong on my first attempt: I had the webcam set for 320x200 resolution. Mike quickly pointed out that the native resolution is 640x480 and my image scale would double simply by selecting this. I'm pretty sure you're using the full resolution though.
I cannot emphasise enough how much the assistance of people on this forum helped me rapidly develop my technique. Mike, Matt, David, Jeanette and Bird (among others) all offered invaluable advice to me and I am deeply indebted to them all.
You do really need a barlow. I happened to have a Celestron Ultima 2x Barlow lying around that I'd never really used much. In truth, I wish I had a 3x or 5x Televue Powermate.
I don't own a Powermate, but from the image scale you are experiencing, a 5x might be good.
I'm actually very impressed with the amount of detail you have been able to capture and would be thrilled with that result for first light of the camera. Remeber that my first Jupiter was far from my first image with the SPC900NC.
As originally pointed out to me by Jeanette (jjjnettie), you can increase image scale by resampling in RegiStax. The better the seeing and the more frames you have, the better this works. I pretty much was always resampling 2x on Saturn. If your Jupiter was 2x bigger (4x the area) is would look heaps better.
You can do the resampling without buying any new equipment.
Don't hesitate to ask if you need specific instructions on what I mean.
Excellent result for first light Alex
I'd be thrilled with that
Take care,
Doug
