Eyepiece Barlow
Upgrade high-powered eyepiece?
I have a Celestron Starhopper 8 inch dobsonian telescope with a 1219 focal length.
My eyepieces:
GSO Superview 42mm (68 degrees) – blurry and can’t focus b/c of fast focal ratio
GSO Plossl 32mm
Meade SP 26mm
Celestron E-lux Plossl 25mm – redundant
Celestron Ortho 18mm – small fov compared to orion
Orion Ultrascopic 15mm
DSO Plossl 12mm – inferior to orion
Meade SP 9.7mm – OKAY
Meade Telenegative 2x barlow – needs drastic focusing as with barlows after insertion
the only eyepieces I use are the 32mm, the 15mm and the 9.7mm but I don’t particularly like the 9.7
would you recommend that I buy another eyepiece or just use my 2x barlow on my 15mm to save money?
and if so, what eyepiece would you suggest? my budget is under $100
I recently tested one of these eyepieces and found it excellent. Very slightly over your budget (by $5):
