Prism Advanced Camera 3 Plate solve

[amstpils]

I purchased The Advance version for the third camera to be used with a Celestron 9x50 finder scope and Meade DSI for plate solving. I have not been able to plate solve in Prism using this combination with an image taken by camera three using a 15 second exposure,
I can take a picture with this combination in PHD2 for 5 seconds and save a file, open in Maxim and plate solve it successfully.
I can also open the same file in Prism and plate solve. it successfully.
I have attached two screen shots that show the Image, Fits Header and the screen stretch.

Prism seems to be setting a low ADU at 0.

I am trying to run Olivier Thizy's script and need to get close to the slit.
As an Alternative an EXE script to add to Thizy,s script to take a save an image from PHD2, where I can then open and plate solve.
Thanks, Al

Not sure I can help on this one. @Hamza Touhami calling you in !


From the first screenshot I can tell you my personal experience with Prism is that it's plate solving likes to have a 2x2 binned image for whatever reason this works wonders for my ZWO cameras. If I feed the prism plate solver a short exposure 1x1 it wont' solve, but as soon as I change it to 2x2 binned, poof, it's solved in 2 seconds.

Can you please send us the fits file that is not solving, I am sire it is a small matter. Dropbox link of Google drive is fine.

Here you go 1 binned 1x1 and another binned 2x2

Can you post the actual FITS files to dropbox or similar? Can't really tell from the screen caps, need to work with the data.

Any screenshots posted can only be of PRISM, it is our main concern.

close the topic.. While the DSI worked in PHD2 the driver apparently doesn't work with Prism.
I replaced the camera with a ZWO ASI 1120
