I am a new SCT owner (Celestron Nexstar Evolution 6 inches). Being also a Dob owner, I already have a functionnal collection of eyepieces. With my Dob, I was used to make a massive usage of my Barlow 2x. But I find it hard to use a Barlow with my SCT. I can not put the whole tube of the Barlow in the diagonal. Then I have to put the eyepiece on top... It is not very convenient. And I am afraid everything could fall on the ground!
So do you use a Barlow with your SCT?
My SCT is operating at around 1650mm of focal length. My shortest eyepiece is a 8.8mm giving me 188x. If I can not use my Barlow, I would probably need an eyepiece in the 7-8mm range for a magnification of around 206-235x. Since I need 20mm of eye relief, I would probably go for either a Delos 8mm, a Pentax XW 7mm or a Hyperion 8mm.
