SUN Timelapse Raw 14 March

Hi everyone

https://vimeo.com/89763010

Here is a raw timelapse of the sun with a large prom taken through a pst with a DMK21 (its mono) piggybacked on a meade lx200 10'. 30fps and only 1 shot every 30 seconds. So its about 4-5 hours worth i think. Next time will shoot 1 every 15 seconds.

It's the first time I've piggy backed the pst onto this mount. (Which is also now on a pier and a wedge). I think the polar alignment is good but this timelapse suggests its not not tracking over a long period well. I think the problem might be with the meade custom tracking setting not being sensitive enough. I believe you need 3.5 not 3 for solar work. it seems to be bouncing around a little bit more than i like as well. It may need pec training or some backlash compensation.


Anyway, take a look below the large prominence toward the end of the video - its much more interesting.


Comments suggestions observations welcome. Given this is my first attempt at solar timelapse, I would especially love to hear from anyone who has ideas on:

a) how to make the raw frames better in terms of clarity and of course colour. (I dont want to stack this just yet - just get the timelapse going. I would like to make this better to view.

b) how to compensate for the meade lx200 custom setting. ANY ideas ANYONE?

Thanks for viewing

Karen
