My choice of a short fl ep so far is between something like an Orion Stratus 5mm and these UO orthos. May also consider a Telvue plossl, a lens that I have tested and pleased with, thanks to another IIS member.
Thanks Chris for your comments. Any updates would also be appreciated.
Thanks Danial and Andy, you both seem pleased with the Orthos. Great price. Sacrificing a wide FOV is not an issue for planetary views, is that right.
Thanks

G'day Richard,
12" dobsonian is F5, 127mm refractor will be F9.4, = better resolution.
12" dob has a large central obstruction, the refractor has none, = better contrast.
At least I think that is what I've been reading!
Can't stop for long, not a cloud in the sky, the scope is out cooling down to a current ambient temperature of 5 degrees.
I might get to see some stars before the moon comes up!
Cheers
Chris.
