I'm new here. It's my first post and I'll be receiving my first scope in a few weeks. Kind of a lifelong dream for me. I'm 43 btw.
What I really wanted was an obsession 18"UC. I was even considering the 15" version but owing to freight and tax (I don't live in the U.S.) the total cost of even the 15" would have eaten my eyepiece budget.
Instead I've ordered a skywatcher 18" 450p from a local dealer for $5K. I hope it works well, there aren't any user reviews that I could find.
My question is actually about eyepieces. The optics on my scope have the same figures as the obsession 18” UC. It's a 458mm objective with 1900mm focal length. This means f/4.15.
My dilated eye-pupil seems to be around 6.5mm
Questions:
For the low magnification end, which of these would you recommend best
Model Fe AFOV TFOV Dep Mag Price
Nagler 26 82 1.055 6.267 73 $615
ES 25 100 1.236 6.026 76 $800
Nagler 31 82 1.266 7.473 61 $650
Panop 41 68 1.387 9.883 46 $510
For the high magnification end, I was thinking about ont of these:
Model Fe AFOV TFOV Dep Mag Price
Ethos 4.7 110 0.270 1.133 404 $610
Ethos 6 100 0.314 1.446 317 $575
Do take into account that I might in the future get a coma correction lens (equivalent to 15% increase in objective focal length)
