A 15mm Plossl may be a closer optical match than the GSO, but it doesn't hold a candle next to it in terms of overall performance and ease of use. Think of it instead as 'best for purpose' 
Matt, the Explore Scientific 14mm IS a gem, just priced more like one!  |
Thanks for your comments Alex. I agree that for its price bracket they would be very hard to beat.

The thing about AFOV is that sometimes you find that the extra width isn't particularly useable anyway, with the view fuzzing out towards the edge (especially if you don't have a coma corrector). BTW, I just discovered Mike Salway's review of the GSO here: http://www.iceinspace.com.au/42-236-0-0-1-0.html This is an old review, so I don't know if they have improved at all... |
Thanks Dean. I know what you mean about the extra width. My 30mm GSO SV does a little of that around the edges also. Thanks for the link too, it was very informative.

Shame you can't spring for something better corrected than a 15mmSV, so I'm pleased to read your rethinking the budget. If you do enough visual, sooner or later the spherical aberations of affordable 15mm widi-ish EP's will become obvious, esprcially at f4-5, and you may soon long for something sexier/flatter as you sweep the heavens.
With patience you may pick up a decent deal online, but until then a budget 15mm will do the job and you can always sell the bugger here- they are quite saleable. I think I have converted two of the Bintel 15SV's into illuminated reticle finder ep's, they are a good FL for short 300-600mm finderscopes.
Have fun shopping.  |
I think I need to look at the 12.5mm/13mm range to really balance out my focal lengths.
I've found the Saxon 13mm SWA Eyepieces. They look ridiculously like the Orion Stratus eyepieces and same specs etc. It's fitting into my ideal requirements of a wider AFOV and FL.
Has anyone tried the Stratus/Saxon SWA eyepieces before? I know they're more expensive but not overly. Atropetes seems to have them priced fairly well.

I just think if I went for the GSO 15mm SV I'll be thinking I could've put that money towards something more suitable...
