Hi

I have uploaded my data on "upload1:upload1" and tried the LRGB tutorial. But integration fails with "registeration failed". I do have some bad frames, but indivdual fits look okay

 

Uploaded the lights and darks under a folder "tsk1979 upload". Upload going on at 2.7mbps currently, may take entire night I guess

 

Vincent, can you please help?

You can just upload a subset of your data, like 20 frames of each data type, that should already show the problem.

Hello @vincent-mod did you get a chance to look at my data. I tried various settings again, yet registeration fails. I used a QHY183m with a ES102ED and no flattner

Thank you. With the Beta I was able to get past the no registration issue. Now I have the issue of individual channel FITS being unreadable in ASIFITSview and stacked combined image being totally black

Yes I see that in your other post, still downloading (slow connection), I'll have to get back to it tomorrow unfortunately. Will do asap then.

Hi Tanveer,

Can I see the issue with a smaller dataset as well? Unfortunately I'm having trouble downloading everything, could you point out the data that should be enough to see the issue so I can download a part? Sorry for the inconvenience.

What about the combined fits. I was able to do an integrate per channel but those files return a dark combined fits.

 

Let me upload 3 files from each channel and update you

I'll download the combined fits to double-check and yes 3 files from each should be fine, if you can point out which ones exactly then I can work on those. Thanks a lot for your patience!

@vincent-mod Thanks!

 

You can download 3 files of each type I uploaded here

Files are named as <channel>_time

 

There are a few 300s FITS and a few 60 second fits

 

Download three of each (any three)

 

The tool could not register any of the Ha FITS. But Lum and other channels had 75%+ registeration

 

The issue now I am facing is that the combined FITS for a channel is not openable in ASIFITSviewer, and even the total combined FITS is not openable.

 

So since bandwidth is an issue can you please see

 

1. Why is the Ha channel not being registered, why are the FITS rejected?

2. Why the per channel FITS not openeable?

3. Why is the combined FITS black

Ok Tanveer. I had a look and didn't need to process as I found the signal already looking very strange in a red light frame. Looking at the FITS data, the offset on your camera is set to 0, which is not right. You need a proper offset for it (and all calibration frames).

Thanks!

 

Looks like I messed up in acquisition. I did an offset of "0" while acquisition. Looks like I need to re-acquire the data with proper offset
