IMO, you would be better served to forgo the TMB clones and spend an extra $14 on Astro-Tech Paradigm Dual EDs from Astronomics. The shortest focal length that they have is 5mm, but how often do you need anything shorter? If you need higher power, use a decent quality barlow.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe

Quote:I thought 140 times mag for a 70 mm scope is pushing it. That you would need perfect conditions to see a clear image.
Quote:Thanks! I not only considered this very Barlow but called Astronomics and he said; while barlows are good and "work", they add glass in the path and therefore darken the image slightly. The Barlow idea, (and I do like the one you suggested) does give me in effect 13x, 26x, 70x and 140. So I am torn on getting the barlow vs getting either a 3mm or Stellarvue sells the 4.9mm giving me 85X. I will be in AZ with hopefully good skies but once back here in light polluted PA, I will want to have good use of whatever I drop my money on.
