Thanks Derek, I appreciate your comments and likewise, always good to hear from you.
I took a series of 30 frames at 10 secs, ISO800 and F8 and then Exported the CR3s in LR as TIFs. I then used ImagesPlus (Mike Unsold – now free) to crop these to 4094x4096 around the centre of the Frame and saved these as TIFs.
I then dropped these TIFs into Austostakkert!3 to Align/Stack the 30 Frames and was surprised at how the EOS R5 was able to handle the dynamic range without the need for HDR processing.
Also, I found that if you use a Canon 12mm Tube between Extenders, you can get them to mate and this combination does focus on infinity – photo attached.
Cheers
Dennis
