Advise for an EP for Nexstar 8"

[Sotein]

Hi guys

what do u think about buying this one for my NEXSTAR 8" ???

Sky Watcher SkyWatcher 1.25" 6mm UltraWide Multi Coated Eyepiece

thanks !!

I would say 6mm is on the short side for an 8" SCT. 7mm is my shortest, and that is not used that much. My 10mm and 8mm EPs see much more use

Too short, an 8mm may work OK but I suspect a 12mm would be better and used a lot more.

T31 Nagler would work very well

Yes agree far too much magnification although your seeing is likely a lot better than mine in UK.  I use a Hyperion Zoom in my C8 which is great but on most nights I don't get below 12mm, then on good nights down to about 10mm, after that I lose sharpness

This is what I bought for my CPC 800.

Gives 235 x.Worth every penny.

I had the XF8.5 and it is VERY good indeed. I only sold it when the Delos 8mm edged it out in my planetary set (between the XW7 and XW10), and the WO Zoom II 7.5-22.5mm made it (and a 14mm Radian, and a MaxVision 20mm) redundant.  The XF 8.5 is a touch better than an 8mm Radian, and that is saying a lot. Very sharp, very comfortable. It saw quite some use in my C8

+1 for the 12mm. That's usually the limit I take the magnification to on my CPC800.

Another one here for the 12mm. Gets more use than my 8mm with my c8

Wow... thanks guys for the advise... lot of answers 

Sadly, the XF 8.5 is out of my budget for now... what about an X-CEL 9mm or a Luminos 9mm ???

[michael.h.f.wilkinson]

Just to add a comment on the 12mm: My 12mm gets a lot of use, but on most nights I an use my 10mm as well for planets. The 12 sees more use on compact DSOs like smaller planetaries. Seeing must be really bad to make the 10mm I have a step too far. I had a Vixen LV 9mm which saw tonnes of use in the past. Very good indeed, so 9mm is OK, I would say. The Xcel-LX EPs get a good press, but the Luminos are a bit of an uknown quantity. I think both will do well in an F/10 scope, however. How they perform in a faster scope is another matter (I simply do not know)

You could try an Astrotech Paradigm 12 mm. I have a BST Explorer for my C9.25 which is the same eyepiece with different branding. Excellent for the money.
