I
believe you said ¡°EAA¡±.. i.e. you¡¯ll be looking at the computer
screen?? If that¡¯s wrong, then ignore this message..
?
If
that¡¯s the case, then you don¡¯t need anything remotely close to a
Paramount or a 10 Micron, you just need a G8 or G11 etc that can hold the
optics.. It¡¯s all about image scale.. My small chip camera has an image
three times bigger than my computer screen and displaying the entire image
squishes (scientific term) it down.. I get fantastic views from my cameras of
30s unguided.. Simple guiding for an onscreen view would be easy.. You would
only need the perfection of high end and expensive equipment if you wanted to
image for long periods and process them to perfection..
?
Point
being, I thought this was for EAA imaging and that was forgotten along the
way.. For EAA ¨C and even for perfection ¨C Losmandy mounts are most
certainly the best ¡°bang for the buck¡±..
?
If
this has nothing to do with EAA, then forget I said anything other than my G11
is fantastic and I am very glad I was convinced to get one..

G11T vs AstroPhysics - opinions wanted
?
Thanks a ton for these latest replies!!!
Yes, I do know the added costs.... (my spreadsheet is a scary thing to look
at).? ?It's the same story with all the next tier mfgrs I've looked
at (AP, Paramount,
10micron, & Planewave), in some cases even having to rebuild/modify the
observatory.? I can convince myself (& the CFO) that the cost is
justified.....? but I have doubts that I really need to go that far.
Chip, your comment really hits home.? I'm looking for a relatively high
capacity, strong mount that tracks very smooth.? I have several scopes
(mostly mid-tier) and I change them often to suit the season/targets.? As
such balance and position often changes a bit, so parking position for easy
restart and pointing models are mostly irrelevant for me.? The level of
controller I have with the Gemini 1 (or even with my Celestron) is more than
adequate.? My problem is drivetrain errors that impact good guiding,
mainly backlash and PE (not the averaged PEC, but the higher frequency
errors/roughness).? ?I don't know if its really necessary to spend 2
or 3 times the price to get those improvements in the gear train, or would much
of that cost be for things like optical encoders and fancier controllers?
I'll think seriously about getting a G11G as a tryout so to speak before going
all-in on a Mach2, particularly if the wait for it gets pushed out
further.? The G11G may be just the ticket.
Thanks again,
