30mm+ EP for spectacles wearer

[Jules Tohpipi]

Hi,

I have a Skywatcher 200p DOB and looking for advice on a 30mm+ EP please. I've obviously looked through some older posts. But I wear glasses and have astigmatism, so are there any EPs better suited to this role?

Additionally, is there any special advantage to a 2" EP over the standard size? Or is it just a case of judging each EP on its own merits?

Obviously I'm looking at DSOs and I have easy access to non-LP skies.

Happy to buy new or secondhand. Budget is up to £100 if justifiable, but lower is better.

Thank you.

The SW 32mm Panaview has plenty of ER and a nice large occular lens, plus your scope being F6 won't tax it too much at the edge of field. £80ish.

This could fit the bill for you.....

The 30mm has 16.7mm of eye relief so should be just about ok with your specs.

Are your specs varifocal or fixed?

Varifocals can cause problems as only a small area of the lens give a particular correction.

Most 30mm + eyepieces have generous eye relief.

Skywatcher Aero ED is a good one. Just make sure your glasses is fix focus and clean. Varifocal doesn't work for astronomy.

You can also use Televue Dioptrx astigmatism corrector on all TV eyepieces and some third party model. 42LVW is one third party eyepiece that works well with the dioptrx.

Thank you for the replies so far. I don't have varifocals, they're fixed.

Another vote for the Aero ED here. Nice, comfortable eyepiece to view through and a twist up eyecup so that you can find the eye placement position that suits you. The one that Damo links to seems a good buy - almost half price.

Thanks for the suggestions. I notice the Panaview has a bit more ER than the Aero. Are they both acceptable in that regard, or will I appreciate the extra ER on the Panaview?

The best bet is see if a local astro supplier (Scope and Skies) can get both in for you to try from their warehouse. On the other hand, just buy the Aero and if it doesn't suit, sell it on for no loss beyond postage.

I have the BST's and like you glasses and astigmatism. Find they work fine and the resultant field is the same for the 25mm BST and the 30mm plossl.

With them they are fairly parfocal so less refocussing when swapping, assume you get others in the set however, but they also have the same eye relief across the set.

I'd say nearly all 30mm eyepieces have comfortable eye relief. A Plössl has roughly 24mm of eye relief at that focal length.

Thank you everyone for your help. I have bought that Aero ED EP on Astrobuysell. As you say, I should get my money back if it doesn't suit. Fingers crossed though.
