It sounds like that Pan24 and the Nagler13 is a winning combo. Then I think I can't go wrong either with the Pan24/Denk14 combo either. I have just got my costs in and either way its looking to be around $900NZD for the two eyepieces landed and duty paid for in NZ. So am off to the bank today to top up the credit card so I can do the order.
Again, a massive thanks to you all for all your input and advice.  I will be sure to get the wife to place some comments and her thoughts on the eyepieces once she gets them to help other people who may be in the same boat. |
Hi,
I am assuming that because it is only your third anniversary your wife is fairly young. ie < 35. However before you drop your hard earned $NZ 900 can you (if you dont mind) tell me how old your wife is and if she wears glasses at all?
The 24mm Panoptic and 13mm Nagler are both great eyepieces but neither are suitable for use with glasses on. They also may not be a great choice for someone > 40 who may develop astigmatism in their own eye in the short to medium term. If she doesnt need glasses the 24mm Pano is a great choice. If she does need glasses the 21mm Denkmeier or the 22mm Vixen LVW would clearly be better choices.
The 13mm Nagler and 14mm Denkmeier are very diffferent eyepieces. The 14mm Denkmeier clearly outdoes the 13mm Nagler in terms of comfort, contrast, light throughput, on axis sharpness and neutral (whiter) colour fidelity. The Nagler is smaller, lighter and has a greater FOV. You need to consider which performance criteria are likely to be the most important to her and base your purchase decision on that. I have used both pretty extensively and I personally prefer the 14mm Denkmeier. I don't own either because I have a 12mm Nagler T4, a 13mm ETHOS and a 14mm Pentax XW. Of those that I own in my F4.5 newtonians I prefer the 14mm Pentax XW combined with a paracorr. If I didn't own those 3 and was buying from scratch I would be buying the 14mm Denkmeier. That all having been said the 13mm Nagler is still a very fine eyepiece and your wife would be very happy with it.
In regard to the 10mm eyepieces the 10mm Pentax XW/XL's have IMO been the benchmark at this focal length for more than 10 years. It has taken Televue almost 10 years to catch up to what Pentax were producing in terms of coatings and glass types when they produced the 13mm ETHOS in 2007. The new Delos uses the same technology as the ETHOS in this regard. Also keep in mind that 50% of Americans (Cloudy Nights) rate eyepieces from the heart and will rate an American grown product ahead of the competition, even though it might not be. Any differences between the 10mm DELOS and the 10mm Pentax XW will be very subtle at best IMO.
The refocusing issue is a complete NON ISSUE IMO. I have 20 + eyepieces the majority of which are not parfocal. I just put them in and refocus. It is no issue whatsover IMO. If refocusing is an issue to you or your wife you can make all of your eyepieces parfocal by putting a 10 cent rubber "O" ring on the barrel of each eyepiece in the correct position and using the "O" ring as a barrel stop.
