I've been using and enjoying a nice GSO made 10" dob now for a little while and now I'm looking to upgrade to a premium model ( New Moon ) 15" or 16" F4.5. I've read quite a bit here that these are the " sweet spot " apertures that really take DSO observing to another level! I'm keeping my 10" because its such a good scope that's not to terrible to move around.
I understand the move to a 16" over the 10" is a FULL magnitude more, and will be profound at the eyepiece ( thanks to folks here who have shared these experiences )
Would having a 15" really be that much different?? I realize I might be splitting hairs here, but I would really like to hear everyones opinions on this! My rationale is the 16" is bigger, heavier and a little more expensive, knowing the very real phrase " get the scope you will be able to use the most "
I'm 6' 48 years young, pretty fit, and have a 4x4 truck for moving the beast haha.
I regularly drive to a Bortle 2 sky about an hour away from Salt Lake City, so I going to be lifting the scope into the bed of the truck. Galaxies, Galaxy clusters, PN will be the main targets with the new scope.
Would I be missing much going with the 15" or is it, well your already getting a Big one you mind as well get the 16"
Thanks for reading,
