Eyepiece recommendations

[mcut]

will hopefully be receiving Megrez 72 by end of January.

I have a skymax 127 Mak with 1.25" diagonal and my other eyepieces are 1.25", Swan 9mm, Baader Ortho 7mm and two Skywatchers that shipped with the Mak at 25 and 10mm.

i want to get an eyepiece around £100 mark or under for the 72mm APO. I have read up a bit on exit pupil and true field of view. i was looking for an eyepiece around 25mm to 32mm. as my diagonal is 1.25" i am thinking of staying with this barrel diameter. is there a maximum mm (32mm 40mm) eyepiece that i can use with a 1.25 barrel, will going over a certain mm cause me a problem.

so far i am considering Televue 25 or 32 straight plossl, cant afford the nice toys, or a SWAN 20mm as the barrel for 25 is 2". the televue scope would be fast so i am assuming i need to get eyepiece that has no drop in clarity towards edge of field, i understand that televue plossl are tested on f4 scope but are they too old now to compete with newer models. I have read varying reviews of the hyperion 24mm.

any tips or advice from all, and in particular those with shorter faster scopes. the 72mm has focal length of 432mm.

Firstly here's a very good article that I urge anyone new to astronomy to read:

How to select an eyepiece

Secondly, what is it you are trying to achieve with this eyepiece you're looking to buy? They'll be fairly low mag in your Megrez, so is it for widefield views?

i would like widefield views around the 2.5 to 3+ degree mark. i have more powerful eyepieces already that i hope would be adequate

in particular i wanted to ensure i had respectable widefield views even off axis

A Meade 5000 26mm might work well in a Megrez 72mm - that would give you a 3.6 degree TFoV and they are pretty sharp I believe. They cost less than £100 as well

I would second that recommendation. I have used the 20mm version (unlikely to differ greatly in performance) and was impressed at it's performance. However, if you don't mind a slightly tighter eye relief, it might be worth waiting for a 24mm Tele Vue Wide Field second hand. Tom Yates had one going for 70 quid recently, and for that money it's very very good.
