How often do you use a focal reducer ??
Not sure if I want to hang onto the f/6.3 focal reducer Bintel sent me.....
For those with 2000mm SCT's - how often do your use a 6.3 to increase your FOV for imaging ?
I must say that the un-adjusted 2000mm FL matched the image size of 47Tuc perfectly - and I imagine for galaxy imaging even more FL might be handy.
