Explore Scientific 5.5mm 100

[Richard Hather]

Hi everyone I'm considering purchasing the above ep in the coming months.

My question is would 273 mag be to much for our uk skies?

I would be using it solely in my 12" dobsonian I've barlowed my 13mm ethos before now with success but as always before making a purchase I would like to hear your opinions and wise words ?

I use my 6mm Ethos and 5mm Pentax XW a lot with my 12" dob. The 6mm (265x) tends to be my regular eyepiece for Saturn, planetary nebulae, busting globular clusters etc and the 5mm (318x) is my best lunar eyepiece if the conditions are reasonably good.

So, yes, I think the ES 5.5mm would get quite a bit of use.

Same here, I use my 7mm XW in my C8 (290x) on Saturn, the moon and Mars quite a bit if conditions are right. Dutch skies are very similar to UK skies (similar amounts of cloud and rain )

I talked myself out of buying a 5mm eyepiece for similar reasons for almost a month  A 5mm BGO popped up on ABS and my resistance broke. I've had lots do use out of it since so no regrets. Someone said to me that you may rarely get to use an eyepiece that gives you the max magnification for your scope but on those special nights where conditions allow for it, you'll be kicking yourself if you don't have it!

Cheers everyone exactly what I wanted to hear looks like the ES 9mm and 5.5mm will be my high power eps then, time to get saving those penny's ?

You might also consider the Lunt Engineering HDC XWA 5mm 110° eyepiece.  Slightly wider, dual 1.25" and 2", and a good performer from what I've read.

Interesting looking ep but if I'm honest I will probably stick with ES I love the ER and the way the eps feel ?

Makes me wonder why I have the ethos ?
