Re: PEMPro on ASI6200 & QHY600

Hi Stuart,

That's a good suggestion and may solve the problem. It depends on how the camera's driver works. Bill said he tried binning but that didn't seem to help which might mean the somewhere a full unbinned image is being downloaded first and then binned in computer memory. I don't know as I don't have one of these cameras to test with.

Ray/Bill - can one do this using a sub-frame? I know that when plate solving I can choose whether to use the
whole frame or a sub frame. In that case, the file sizes would be quite manageable. But I don't use PEMPro (yet;
looking forward to trying it tho).

Bill,

I can't be sure because I don't have one of those cameras but this issue might not affect PEC acquisition
since only one full frame
image ever needs to be in memory at a time. From what you told me the problem with allocating the
Bitmaps doesn't occur until
PEMPro's polar alignment steps that requires three images to be in memory simultaneously. Each image
can use 60M * 4 bytes (240MB),
resulting in 720MB of memory out of the totally available GDI+ memory (1GB). Successful allocation of
those images also assumes that
the 1GB is not so fragmented that the large chunks can be allocated. If the graphics memory cannot be
allocated you will get the
error message you have reported.

Is there a possible solution? Maybe, but it may not be a quick and easy fix. It may also require purchasing
or borrowing a $5K
camera to test with. Plus, privately and publicly you seem to be demanding that I drop everything I am doing
to perform an immediate
fix for a camera that just came out that is causing an unexpected problem for which there may not be an
easy fix.

I told you privately I would look into this, but it is not likely going to be done soon and I can't promise you a
solution. If that
is not acceptable to you then I can refund the money you paid for PEMPro even though you've been using
it for years.

Best regards,
