I thought my only option was to use a Paracorr with a higher power eyepiece.

Hi Mark,

Although I've never used a paracorr, I have always thought this combination was possible. I went away and checked and found this reference on Bintel's site:

Note for Dobsonian/Newtonian Owners
When using Tele Vue’s Paracorr coma corrector, the 2.5x or 5x Powermate™ should be inserted into the Paracorr’s 1-1/4” adapter (i.e., between the Paracorr and the eyepiece). For 2x and 4x 2” Powermates, first insert the Powermate™ into the focuser, then the Paracorr into the Powermate.

Have a look at the 2.5x Powermate in the eyepiece section and click on all product knowledge and go to the bottom.

I would have thought going to a higher power, hence narrowing the field, would make coma less of an issue and eliminate the need for a Paracorr. I suppose it ultimately depends on your optics and what you consider is acceptable.

I hope this helps.

Regards

Glenn
