Moonfish where to buy....

[Doc]

Anyone know a uk distributor for the Moonfish 2" 30mm eyepiece, my Dad wants to buy me an Xmas prezzie.

Cheers

I think you just buy from their website:

Maybe worth asking Gaz what the 30mm is like in a fast dob?

I'm not the fussiest when it comes to edge performance in eyepieces but the 30mm 80 deg is dreadful in my f 4.5 scope, unusable as anything except a 'finder'. The Moonfish 30mmm 70 deg model is MUCH better in fast scopes IMHO.

[Doc]

I really welcome your advice Gaz.

The 30mm 70 degree one looks good at £49 but for the same price there is the 42mm at 65 degrees.

Would the 42mm at 65 degrees be any better Gaz

[GazOC]

I've no experience of the 42mm sorry Doc, but if you can get the same (ish) FOV and a smaller exit pupil out of a higher mag eyepiece then I'd probably go that way TBH.

[russ]

Doc, the 42mm will have an exit pupil of 9.33mm with your 16.

[russ]

You could try one of the new Skywatcher Panaview eyepieces? They do a 32mm 70deg. Exit pupil remains sensible (7.1mm) but true FOV is quite good at 1.24deg. Edge correction is supposed to be the same as the William Optics Swan. I have the Adler 26mm, another Swan clone, and the central 40% of the field is sharp. Between 40% and 70% it's not too bad. And then from 70% out it's seagulls.

[Doc]

Thats alright Gaz I definetly agree with what you say.

Rus 9.33mm is pretty large, how big is an adults pupil. It may be difficult to hold the eye in the right position to get a good image.

[russ]

A young adult has a 7mm exit pupil. But an old(ish) bloke (like me) i think is about 6mm.

Cheers I'll go and look it up.

Well mine will be about 4mm then. LOL.

Only joking Mine should be about the same as yours.

[russ]

not sure what the budget is but the Adler 32mm is £49 delivered. The Panaview is £69. The Panaview looks to have a nicer finish with screw up eye cup. It could be the coatings are different too.

But from the feedback i've read so far i would say they perform identically.

If you want a proper nice low power eyepiece there's a 30mm TMB Paragon on UK Buy'n'sell for £100 at the moment. That will be far better corrected compared to these SWAN clones.
