Yes, this is from a new all-in-one SHG, with longer focal length than before. Hope it can give better spectral resolution.

Wah

You may compress and upload the file to google drive or dropbox and let me have a try.

Wah

This is a quick first light in the morning before going to work.

Wah

What error did it show? Or it never prompt error when the file is over 3GB?

Wah

Which file format and what size do you need?
As far as I remember, I was using an external library for avi format which cannot handle larger size files.
Then a newer version could handle mono-color ser files without problems (I guess).

Wah

After a long leave, I am now redesigning the spectroscopes and creating the parts by using a 3D printer.
Some optical glass slits have been used also, I hope the overall image quality can be improved.

The PST uses compression tuning. The Teflon ring in the chamber is the main point of pressure. The silicone ring ( the orange foam) is designed to smash the etalon until it comes into tune. Since it never compresses evenly the silicone ring is trimmed and cut so that it applies pressure as evenly a...

Two pieces of LARGE diffraction grating 20g/mm, about 10x10cm, with transparent protection covers.
Not sure how to use them, I guess they are Echelle gratings.
$50/piece + shipping
Sold as is.

Thank you all!

Wah

Wow~!!! Really very high resolution images!!!!!

Do you have more information about the equipment? Thanks!

Wah

I can see the Ha line!
Just kidding

Congratulation for this wonderfull set of images. They are beautifully processed. Do you have a full resolution version of this image ? https://solarchatforum.com/download/file.php?id=29184 I am working with the French Astrophysical Institute of Paris, and I would like to check some details I have ...

Amazing what you have accomplished, Wah! Your latest result is easily as good as Druckmuller’s famous pictures. Your Photoshop technique seems related to some of the multiresolution wavelet sharpening methods available in some image processing routines. Have you tried any of these? Cheers. Peter. I...

Based on Mr. Miloslav Druckmüller's HDR and ACHF method, I processed my images again trying to squeeze all the tiniest details from them, and finally got this final version.

Because this is a final version image, i post it here

The camera ASI174MM theoretically can have 128fps, but I just could get about 100fps because of drop frames.

Wah

Captured it without moving, at my home!!!!!!!
What a good luck I have~~~!

Thank you all! I took my EQ mount, telescopes, laptops and cameras to the eclipse, and the cameras where following the SharpCap Python scripts I prepared to capture different exposure frames (0.001-4s) during the 2 minutes totality. After coming home, I extracted the frames from SER video file with ...

New corona enhance method result.

Wah

Steven Rosenow also got a VERY good result by his own processing technique, very close to ACHF result.
I wonder if he is in this forum?

I have been searching for the best total solar eclipse images, and found that the images by ACHF (created by Prof. Miloslav Druckmuller) seem to be the best of all. Is there anyone here have tried such filter? Prof. Miloslav Druckmuller's eclipse photos: http://www.zam.fme.vutbr.cz/~druck/Eclipse/Ec...

Congratulations, Alexandra!

Wah

Sorry, forgot to mention, you have to choose another image during the "apply image" action.

You cannot use the "difference" option in layers to finish the task. 1. Duplicate the original image as another one 2. Radial blur the original image 3. Use new image to subtract the blurred image with 128 offset (gray) 4. Copy the subtracted image to clip board 5. Restore the original ima...

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.

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!

You may try ROI fucnction in SharpCap rather than Firecapture.
