Glad to see the new filter wheels are finally available. what is the procedure to exchange the old filter wheel that came with my QHY22 for the new filter wheel with the 6 1.25'' filter slots. Thank,

Software Release and Development / Re: Missing Images with EZCAP

Dear Sir,

Thank you for your quick reply.

Yes, up till now, EZCAP has added a number if I was using a duplicate file name.

The file name I used was m31.
The folder name and file name was:
  2014-07-30. COONAqhy8l/m31

Thank you.

Ross

Hello,
         We will test at the same sequence to see if it has problem here.Normally speaking the EZCAP has a auto-rename function , if it meet the same file name in the folder. it will add -1

         for example,   a.fit      a-1.fit    a-1-1.fit.....

Software Release and Development / Missing Images with EZCAP
« Last post by Ross G on July 31, 2014, 03:32:03 PM »
Hello,

I have just had 4 nights at a dark site imaging with my QHY8L and using EZCAP to capture on Windows 7.
All went well except for a strange problem on the last night.
I was imaging M31 doing 600 second exposures. I decided to extend to 1200 second exposures so I pushed the "FORCE STOP" button in the EZCAP Planner window.
I changed the exposure time to 1200 seconds then pushed the "START" button. I did not change the file name, leaving it as M31.
I did 3 x 1200 second exposures. However, when I looked into the folder I was capturing these 3 files were not there!
I have searched the computer but cannot find these files.

I am concerned. As well as having lost 1 hour of good images, I am worried that this might happen again.
I get very liitle time at dark sites and I always use EZCAP to capture my imgaes.

Could I be doing something wrong?
Is this a fault in EZCAP?

Thank you for your help.

Ross.

Hello,
        The video is very clear to show the image process method. Also I like this image very much.

Basically, such kind of combination could be done using some tweaking of the transmission curve for each channel.
Here is an attempt to approach to the task using the histogram only. The blue channel switched off, the red has big "hill" in the brightness range of prominences while the brightest pixels representing the disk are suppressed. The green has small "stair" which slightly brightening the edge of the disk in G-channel.
