Hi All
Further to my first post on upgrading my Optex 8", I have been looking at 10" and 12" GSO dobs from Bintel and Andrews.
Considering the economics and light gathering potential, the 12" looks better
than the 10". Unfortunately, the 12" with a 1500mm focal length is not very portable
compared with the 10" with it's 1250mm focal length.
On GSO's site the 12" dob has a focal length of 1250mm, yet both the Bintel and Andrews GSO's are quoted as having a 1500mm focal length.
Does anyone know if it is possible to get the GSO 12" dobson with the 1250mm focal length as on the GSO home site please?
Otherwise I'll go for the 10", but am worried that I could be missing out on some serious aperture with the 12".
Thanks
Pete
