I made it as a planetary imaging scope with visual use on the side. I needed it fast to keep it short for using it on an eq mount.
A longer fl would have been better no doubt but just wouldn't be possible to mount the thing.
The figure ended up very good, it'll holds up very well at very high powers well over 500x so long as the mirror is cooled as it's plate glass and it tests a bit over corrected if the temps are dropping too fast.
