Hey Alex,
If you have have some short refractors already go long. I have only owned my 925 edge HD for a short amount of time but the challenge is not that crazy. I am doing it from my inner city Melbourne light polluted suburb and if I can do it anyone can. The Celestron T adaptor makes back spacing a breeze and a OAG is a must as is an EAF.
Also shooting at native F10 is not bad. I think a reducer adds complications.
Go for it!!!!
Cheers,
Dilshan
