not fair! You have amassed quite a lot over 2/3 years  and i admire that because i probably bid against you on some things over the years...but after knowing you these past few months/ years ...we are all alike...All the best Brian and more power too you. You do have nice collection and you do alot of work too restore them.With that said,keep sharing information. Thanks,john

tried this scope out last night
and its definitely not up to par in my opinion.
looked good on moon.
did 7 sisters and looked good also
when i did orion it was good up to 200x
and when i used a barlow at 400 things kind of washed out.
when i did a single star test rings were concentric
but outer ring in and out of focus was flared.
i think spacing might be off as things were close
but not good enough for 75mm unitron.
ill have to do a little more experimenting
on this one.
more to come.

Brian,
Good idea to try and tweek it. Let us know your results. However I can attest that all Unitron lenses are NOT created equal. Good luck and keep us posted.

hi bill,
yes i agree about not being equal.
when i view a single star i see no coma but
view could be just a bit crisper.
did flashlight test in dark with bright red light
and all looked good.(no spots on lens center)
i had one a bit back that should have been .005 gap
and views were not good till i hit .008 (my 4" Edmund)
maybe i will re space in early morning when i get home
from work. (its raining again)
it could be a bad lens but i have a feeling it just needs
a little tweaking. it was close but not there.

hi john,
no i have not tried yet.
maybe i will today before work.
it was cloudy last night so i did not get to try
the worm gear 140 out.
i would not mind having these 2 side by side for a comparison.
i better get on it as the boss asked me how busy
i am in my room and i said real busy.
they just started working some guys 12 hour shifts
last night an i have a feeling i am next.
that means eat, sleep and work for next 2 months.
Brian

if this is no better than first check
i will go to .006 or .007 and see how that works
and it might take several tries like my
edmunds 4" but it was worth it.
