17mm Type 4 or 16mm Type 5?
Hello all,
I need a wide-field eyepiece in this focal length range to use on a 12.5" f/5 Newtonian. Just wondering if anyone had an opinion on which is the better eyepiece. To be used mostly for DSOs (globulars, open clusters, smaller nebulae, etc.), with and without UHC filter. |

Greg,
I have a 12.5 dob (Dis. PDHQ). I bought a 17mmT4 for it and works GREAT. You'd love it I had (and still do) have a 16mmT5 at my disposal to re-assure myself now and then. A nice (very nice) surprise was finding out how sweet this 17mm works with my TV 102 too! What a sweeper in the Milky Way...It can't get any better. It is the best ep I have for a 50-50 use with my two scopes. Many nights I use the 31T5 and the 17T4 only. And the 2" ep will work better than the 1.25 with the UHC IMHO. The 16t5 & 17t4 are mighty fine ep's indeed. Good luck..clear skies buddy. |

I have the same set up too. But I use the Paracorr left in all the time.
This combo works well with my other EP 27mm Panoptic and 12mm Nagler and 12.5" dob. Matt "Louis" wrote in message oups.com... Greg, I have a 12.5 dob (Dis. PDHQ).
