if you plan on doing a bit of observing through the scope as well as imaging this might be worth considering

it will give pretty close to the same fov as an ed80 but being 6" it will also allow you to 'see' a lot more, certainly a very nice ota to look through especially with my 24mm Panoptic.
if you were going to purchase this ota i'd ask if bintel could fit 10:1 low profile focuser for you which will definately make it a lot easier for imaging.
its also probably worth mentioning that once you get started you will almost definitely want a coma corrector like the MPCC/Paracorr. and for what its worth i will be using a MPCC as its a lot cheaper than the Paracorr and doesn't affect the focal length.
