Re: Late solar eclipse photos

I used AS!3 to stack the same exposure frames and used Photoshop to combine different exposure stacked frames with layers. Oregon is too large, days go too fast, we never had enough time to watch everything there in detail... BTW, forgot to mention about the videos we took during the eclipse: C3: ht...

Re: Celestron C8 F10 + PST CaK + SAFIX test

Re: AR12665 M1.3-class solar flare

Thanks all!
I guess I have to crop the center part for another animation because the wide field doesn't look very impressive.

Re: ROT2 command of IRIS

Hi Merrill55, I am sorry that the SLiM has some problem to process the avi files because it is using an external library to decode the avi format. If you use the mono 8bit or 16bit SER file format to capture the video, it should be able to support without problem (I hope) I was too lazy to implement...

Re: Question about proms and shg

I don't have example now.
I remember the exposure was much longer than usual Ha imaging as the proms were very dim.

Re: Question about proms and shg

I only could see proms above the limb, but couldn't see special features on the disk.
I think it was because they need ultra narrow bandwidth.

Re: SpecLineMerge update

Just found a bug in the previous version that it couldn't merge properly with 8bit ser.
Please try this newly uploaded one.
Sorry for any inconvenience caused.

Re: SpecLineMerge update

BTW, as I am quite lazy to write codes, the 16bit ser processing is forced to use "horizontal" mode only. :mrgreen:

Re: SpecLineMerge update

I have some old codes for 16bit tiff saving, so I copied that in the program.

Here is another re-compiled for "Any CPU", hope you can run it in WinXP.

Re: SpecLineMerge update

I compiled it for 64bit, don't know if it works in your XP.
If you need an x86 32bit version, I can compile the program again.

SpecLineMerge update + new name: SLiM

Hi everyone, I have updated the program and should be able to read 8/16bit SER gray scale videos.
I would be great if anyone can help test it.
Please remember do virus check before running it.
Thanks!
