Hi all, I am having the same issue. I've just got my new QHY294 and with MPCC mIII and Optolong L-Pro I have the same circle in the middle of the frame, wchich I cannot get a rid of. If I remove the MPCC, it disappears. Is it MPCC or the L-Pro?

Hi sure, will write them, let's see what their response gonna be... Will let you know Cheers!

I was getting decent images even with 44mm (including adapter), but without any reflections, so I thought to give it a try. But for sure you are right. I am using Optolong L-Pro, also used it on DSLR, btw...

I am having the same issue with Baader MPCC mark III. But only with my new QHY294, I believe because of spacer and back focus set to 55mm. I've never had any issues like this on my DSLR with the same corrector. I am thinking to reduce the back focus to 44mm as it was with DSLR. Do you, guys, have other solutions to get a rid of that? I am using 200/1000 newt, btw.

Oh, okay, will need to have a look into that once again. I have just downloaded the ino file and opened in IDE, downloaded and added the library. I have seen some differences, but was not sure in it. Honestly, it is for the fist time I am using it... Thanks for your feedback and support, hope I will make it run Cheers!

Hello there! I was wondering if you could help. I found your setup very interesting and decided to go for it (thanks for that!! ). I am however having issues to compile the code and to upload it to arduino... the error is like this: Do you think you can help? Thanks in advance!
