Problem stacking binned images in Maxim DL

[Helo (Peter)]

I was wondering if anyone knew the solution to stacking images captured with Maxim DL with a monochrome camera LRGB. I binned the L 1:1 and the RGB al at 2:2 but when stacking in Maxim DL (v5.23), it is combining the two different sizes rather than autocorrecting for this as it says it should. This results in a dual image (one larger the 'L' and one smaller RGB in the final merged picture. I looked at the FITS header and it shows all as 1:1 (RGB should read 2:2 and are definitely smaller than L images). Tried reducing the 'L' images in Process to same size (halve) and this worked but bothersome but then also hard to find an exportable format to work on in Photoshop. Any suggestions as to what I am doing wrong? Thx, Helo

Wasn't aware Maxim allowed resizing combine?
From memory you do need to calibrate first, then resize 2x2 img's, then star align, then combine. Save as .tiff for photoshop post processing.

I highly recommend Adam Block's Maxim processing tutorials if you cant still order these.

Thank you so much , the Maxim manual is vague but seemed to imply it automatically resized. I resized and combined which worked but then when i convert to a 16bit uncompressed Tiff, it seems to have lost a lot of resolution when I reopen it in Photoshop, any suggestions there? I will also hunt down those tutorials. Thx again, Helo.

There are a few ways to actually go about processing in Maxim that to write it down in explanatory words will take a page or more of explanation to do it correctly and utilize different processing features.

Email Adam and ask if he still has copies of his DVD MaximDL tutorials. I highly recommend getting these and watching; it will explain hours of processing and stacking tips that one just cant fit into a forum post.

Let us know how you go.
