TeleVue Nagler Type 4 22mm

I love my 9mm and 16mm Nagler. I built a new scope and wished to get the field back I lost from the longer focal length from the larger dobs. I ordered the type 4 22mm Nagler. I felt as if I had been ripped off! The edge showed way to much coma, the lens was heavy (I knew when I ordered the thing), and the instajust sucked! It feels as if the thing is about to drop every time I picked it up. With the coma the views are not that great even in an f/5.

I phoned Televue and they suggest getting a Paracorr, what another $280 on something this expensive anyway. Now I here that I get to shell out $280 more, cut my truss polls, and rebalance my scope, just to get a $445 lens to be sharp at the edges! Wow!!! Televue need to heavily advertise this one!

I am doing all the above but I’ll loose some of the field in the extra 15% magnification! Blows the purpose of going to the wide field to start with. I’ll post the results when done. Don’t get this one unless you have a slower than f/5, a Paracorr, or the extra $280 to buy one!

If you see coma, it's almost certainly down to the telescope. I'm not saying that you have a bad primaray, but the coma on an F/4 Newton is HUGE. No eyepiece will correct for that; they have not been designed to do that. A paracorr has.

Good luck,

Marc
