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...

Late solar eclipse photos
May accidents before and during the eclipse, but still can see the total solar eclipse for the first time!

Wah

Super detail! Is there any ERF for CaK being used?
Where can I buy SAFIX? Thanks!

2-frame animation

Wah

Here is the cropped version

Wah

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

Thanks everyone!
Baader solarfilm 5.0 has been used.

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...

Wah

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

Wah

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.

Wah

Do you mean these lines?

New name version~

Wah

Can I change its name as SLiM (Spectral Line Merge)?

Wah

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.

Wah

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

Wah

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.

Wah

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.

Wah

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!

My friends and I have bought totally 5 books, I got them yesterday!

You may try ROI fucnction in SharpCap rather than Firecapture.

Wah

Let me remove the bands.

Wah

High quality optical parts are the bottlenecks, they're much more difficult to find than other parts.

Wah

I think yes:

Good to see new SHG images!

I need time and weather to take new pictures.

Wah

I am still making mine~

My first question raised
"1. If the light source is bright enough, why should we consider high efficiency?"

because of the topic question:
"does anyone use prisms instead of gratings for SHG?"

Wah

Two questions:
1. If the light source is bright enough, why should we consider high efficiency?
2. Does prism absorb some parts of the spectrum?

Wah

Good job!

Wah

Wah

It should work because it does NOT required advanced functions of PS.

(edited)

Wah

The bands are not perfectly horizontal, so it cannot be removed by normal processing.

Wah

The program I wrote was intended to merge spectral lines only, no deband functions.

You may submit the original and let me help you.

Wah

Sorry for the late reply, here is the result.

Wah

Can you give me the raw so I can help you remove the bands?

I really hope I can have chance to see through a shs in future.

Wah

Can those 5 images be quality filtered + stacked as normal filter images?

Wah

For those large solar telescope with adaptive optics, the details of SHG can be much better?

Wah

Regular slits can easily be dusty and hard to be cleaned, for me. If the blades touch each other, it also can be damaged. Both can cause serious banding problem to the SHG images. That's why I would like to try glass slit instead. For the reflectivity, I can only test visible light based on my camer...
