Coming back...

[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.

[Montana]

Excellent!! I really look forward to your excellent images again

Fantastic Wah! I'm looking forward to the results.

Wah,
Glad to see you back.
I think 3D printing is the way forward. Paul has been active producing his LowSpec spectroscope design, a great introduction to slit spectroscopy.
Are you going to update your SLM software to allow larger files???

[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).

[Merlin66]

Wah,
I've been trialling a fast frame ASI 174MM camera on the SHG, using the x2 RA speed to reduce acquisition time. ( Using an ROI just enough to get the spectral line, I can get up to 400 fps)
The SER files can be up to 3Gb in size....this seems to be an issue for SLM?

[Wah]

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

[Merlin66]

I think it just didn't run.....
(Been a while now due to weather and other issues. I could probably find the file on the computer and check if needed.

[Wah]

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

[Merlin66]

Wah,
Give me some time to find the files.
I'll email you when I'm ready.

It looks very nice!

Welcome back. Looking forward to seeing the results from your new kit.

The refill filament has arrived and more parts have been printed out.

[Wah]

Two improvements:
1. Slit fixing method
2. Print direction

The OVIO reflective slit plates????

[Wah]

Not from OVIO, but tailor-made from China some years ago.

Wah,
I've sent you an email with the SLiM errors, and sent a copy of the AVI file (930Mb) to dropbox

Hi
Very nice job Wah !
I've also a 3D printer, and it's a very good tool to make parts for SHG

I just experienced the error myself this morning, and found that it should be a setting problem. I mistakenly set the project as X86 rather than X64, so it could only allocate a very limited amount of memory. I will post a recompiled version later and let you try.

[Merlin66]

Wha,
Thanks for the feedback.
Your continued support for the SHG is appreciated.
Look forward to trying the new version.

Hi Merlin, are you able to download the file from the above link?

[highfnum]

interesting

[Merlin66]

I’m in transit....I’ll download later when I get home.
Many thanks.

[Merlin66]

Wah,
Downloaded OK
I'll try it ASAP and give you feedback.
Many thanks,
ken

Wah,
Unfortunately it still shows the same error messages.
Looking at the "Unhandled exception" - Object reference not set to an instance of an object
There seems to be references to d:\projects\SLiM_RemovedProcessing\form1.cs.
I assume this was your working directory????
Let me know how I can assist.
regards,
