4 Hours of the Sun in Ha time lapsed

[trent_julie]

Hello,
Just thought I would share my latest solar time lapse effort. I think I have improved my technique for capturing full disk images, each frame was made from a 40 second AVI and each AVI was separated by 60 seconds. It took about 6 hours (Hands off the computer) to process all the AVI's and a further two hours to align process and produce the final image. I was reduced to only 4 hours of data due to the changing of brightness of the Sun, This change in brightness appears to be due to the altitude of the Sun and the thickness of atmosphere.

Equipment used;
Coronado PST
DMK 41
Solar Autoguider

Nice work! I was waiting for the space shuttle or similar to pass by - but alas - no: just moving sunspots!

Thanks for the comments everyone!

I am currently working on a production version of the autoguider, but without giving away too much it attenuates the Sun both in brightness and angular size for conventional autoguiding software to use it. It has taken me years and many hours and $$ to get right, so please excuse me if I remain a little mysterious about it for now. I would like to have it published in a magazine as a do it yourself article, but time will tell on that one!
