Fine Tuning My Eyepiece LinupPosted By Dave Bush |
I’ve got a 12.5” f/5 Dob and my current line up seems to me to be just about complete. Here’s what I’ve got…
26mm Type 5 Nagler -- 61x (1.3 degree FOV)
13mm Type 6 Nagler -- 122x
9mm Type 6 Nagler – 176x
7mm Type 6 Nagler – 227x
5mm Type 6 Nagler – 317x
I’m debating over the Paracorr. I can see coma in the 26mm at about 80% out from center but then again I’m not so sure how much it bothers me. The Type 6 Naglers don’t seem to show any coma.
Anyway, what else could I add to this (or subtract) to fine tune it?
Thanks!
Dave
