Title: Yet anotheeer... timelapse eclipse video
Post by: RobertM on Oct 07, 2015, 22:34:45
One frame taken every 30s using SXV-H694 camera with Ha filter on the RH200, stacked binned and AVI'd (5fps) in MaximDL.  Unfortunately I only caught it till just after the eclipse point as my field of view ran out.

Not quite sure what went wrong with the link but if you click on the black bit then it'll take you to the AVI and a play button.  This version is about 100MB total size but it streams so you shouldn't notice it to badly, the full res one is much larger but only really adds a bit of detail to the surface.

Have one other to process but that may prove more challenging.

100MB !!!  it streams? Really???  It might stream on your fancy suburban cable internet.  Out here in the sticks that would be a 20-30 minute download.

In any case, clicking on that big black square (which I assume is the video) sends me to a Yahoo login screen.

Oops sorry it's public now.

Mark, it was that size on my PC but seemed to stream down ok.  If you have trouble then I'll try 3x3 or 4x4 binning.

Very smooth.  Just puzzled why you used a Mono camera for this event though.

Carole

It was one of the options I used.

I have another version which has the moon flip-flopped to match what you would see with the naked eye and also lightly processed, will post that shortly.

3x3 Binned version for the more rural:

Robert - just to confirm then near end of vid when moon goes really dark/ fuzzy & then back to normally lit is that you adjusting exposure for the fully eclipsed moon? John

Hi John,  yes the exposure increased from 0.02s to 5s - I thought it was the best time to do it.  Unlike a dslr it doesn't have any auto exposure and readjusting manually each time wasn't a good option with two cameras running.
