Another Ask For EP Advice.... yawn

[Liquid360]

I HATE to ask such questions. This is partly because it's just so subjective and personal. However, anytime I simply can't decide I ask here. I'm considering grabbing one last EP, which should complete my collection for quite sometime, unless I add a new SCT which is likely in the next couple months. My three eyepieces makes me feel I'm missing one. The 3.7mm I bought cause I found a good deal, but doesn't see much use. The 13mm Ethos I adore.

I have a 4in Frac, 530mm. My current EP's are TV Ethos 13mm, Ethos SX 3.7mm, and a 20mm ES100. If you were to add a final eyepiece which would you add? I'm torn between Ethos 17 and 8mm. My targets are whatever happens to be interesting on any given night.... Planets, DSO, etc

Someday I'm sure I'll have both, but that time isn't now. One last EP for the immediate future.

The 8mm Ethos is an outstanding eyepiece and would slot in nicely between the 13 and 3.7.

[Liquid360]

Thank you!!! I just happened to look at Astromart and there's a new used 8mm to save a lil money which always helps. Thanks again!

Yeah an 8mm Ethos would be perfect. Then all you need is a big Dob     

[Moonshane]

It's often cheaper to have one eyepiece and a number of scopes!

I have an Ocicat who'd never get along with a big dob [emoji6]

what about a powermate gives you 20,13,10,6.5...

[Mark in Macc]

The 9mm ES 100 deg has a good number of admirers as well.

[Liquid360]

Noted... it also happens to be on sale at OPT for $270 vs $569+ for the TV. The brain says "get the ES stupid!!!" But my heart says "TV's r pretty". Sigh.

This would add quite a bit of weight onto a 4in frac wouldn't it?

not as much as a 17E!

I would go with the 8mm ethos.

As a suggestion you could then get a powermate (potentially funded by selling the 3.7SX?) like Dobfest says and get 4mm along with other good focal lengths for your set.

[Liquid360]

Just to complicate things a bit further, when using my scope for visual work, due to focusing issues, I have to use the TAK extender Q which, according to their site, "Acts as a 1.6x visual Barlow and a field-flattening photographic 2" tele-extender". How would this effect the use of a powermate, if at all?

[Liquid360]

As the new guy, why would a 4mm Ethos be superior to the 3.7SX?

Curious,

It wouldn't be superior but would be pretty much equivalent and you would gain the other focal lengths as well.

I think I see what you did there :D

For fear of dragging this thread waaaaaaaay off topic with more silliness I'll shut up now.
