Hi All,

 

I have a Lunt LS60 Ha that I had my DSLR piggybacked to for the eclipse. Throughout the eclipse I had to manually recenter the telescope so as a result the images aren’t registered. Best yet, with a transiting moon across the sun, any reference point would be likely lost in processing (i.e. stacking) software. I’m looking for suggestions on how I can register the entire stack.

 

All ideas are welcome.

 

Howard R.

+1. I have the exact same problem. The only surefire way I know of to align the stills for a timelapse is to do it manually - something I would really like to NOT do with 300 frames!

 

I will have to test it out, but I wonder if we can auto-align using software designed for panorama stitching (PTGUI).

Here's a copy of a reply I just posted in another thread that was also asking about timelapses.

 

I used PIPP (planetary imaging pre processor) to register 2,520 still frames to make my 2 hr 51 min timelapse:

I did it in 3 batches and made a separate avi file for each partial phase and one for totality. Once I made an avi file for each of the 3 separate phases, I then stitched each of the individual avi files together using OpenShot Video Editor.

 

Once you've loaded your frames in PIPP, click on the "processing options" tab, employ object/planetary frame stabilization and center the object in each frame. For the partial phases, use the "edge in shadow" feature and select the appropriate edge from the dropdown menu. There are many other settings that you can fiddle with as well, including histogram adjustments, debayering raw frames, output video fps and compression options, etc.

 

Hopefully this will get you started. Let me know if you need any more details.

 

Matt

I will look into PTGUi, if nothing else the manual alignment process will work. PIPP usually works well, but for eclipse image alignment it struggles.
