Hello,
I've been naked-eye viewing stars and planets for a long time... decided to go ahead and get a used 8" dob - it came with default plossl 25mm, 10mm and additional 6.3mm and some 2x plastic barlow.
I love the 25mm! But the others are not really fun to use at all due to their small pupil, I don't want to be squinting all the time and I wear glasses as well so it makes it difficult to use them.
I've spent some time reading on the forums, reddit, etc. about all the available eyepieces and what their use case is for various objects, etc.
Still, I am curious what various dob 8" owners have and use on the daily, or what they recommend - I noticed I do have a 2" adapter with the scope - are there any pros or cons of using 1.25 vs 2" eyepieces? What if I were to want to get a larger aperture dob in some years? Are there some overlaps between eyepieces that work for different apertures?
So far, I've narrowed down these options:
Baader Hyperion Universal Mark IV zoom eyepiece + zoom Barlow lens set
This seems widely recommended as the best starter kit you can get for your money with the biggest benefit being convenience. I was seriously considering this one, just because not switching eyepieces seems like a very convenient thing. But ultimately a lot of people recommend just having 1-2 solid pieces such as a 10mm + a 25-30 mm wide FOV one and that for similar money (minus the barlow).
I noticed one user - astro.catshill in his blogpost explains that there also needs to be a 35mm 2" extension that you use if you want to go for this combo. I assume the below extension would work?
Omegon 2“ Extension tube, 35mm optical path - I've heard that if you want to use 2" scopes on the Classic 200P 8" Dob, you might need some additional extension to accomodate the focus (on top of the 2" adapter) - is this true?
Other eyepieces:
Omegon Oberon 32mm 2'' - haven't been able to find any reviews on this online that would give any sort of definitive review. Only some vague posts about it being a copy of another eyepiece and that the 82 fov is actually 70, though the weight of this piece seems overkill...
Omegon Redline SW 32mm 2" cheaper alternative to the above.
Omegon SWA 32mm, 2” eyepiece - similar as above...?
Baader Hyperion 31mm, aspheric - hyperion line from baader seems to get mixed feedback.
Baader Hyperion 13 mm - consensus is morpheus is a better investment, but I doubt I will care much for the more premium lineup considering im moving from the default scopes.
What I also saw was recommended from Chinese options as insanely good for the price (how do these compare to the ones above?):
Angeleyes 70° FMC 14mm 1.25''
Sky Rover 2 inch 70 degree UF 30mm
