Hi Rick, Keep me in mind if you would ever consider downsizing your 155EDF in a negotiated trade for a 2001 130EDF. The wide field 130EDF sure would look Sat, 04 Jul 2009 04:04:00 GMT rick_auerbach http://tech.groups.yahoo.com/group/ap-ug/message/46081 http://tech.groups.yahoo.com/group/ap-ug/message/46081 ... I kind of like the expression... "flickering AP 155"- probably more related to change of mind than anything else.... The disappearing, re-appearing AP 155 Sat, 04 Jul 2009 03:47:55 GMT joelwhicker http://tech.groups.yahoo.com/group/ap-ug/message/46080 http://tech.groups.yahoo.com/group/ap-ug/message/46080 Nope it wouldn't. Although I know to which scope you refer. Rick A. is the seller of that one. I have no idea whether you know him, but I did do a deal on a Sat, 04 Jul 2009 02:58:50 GMT Rick K http://tech.groups.yahoo.com/group/ap-ug/message/46079 http://tech.groups.yahoo.com/group/ap-ug/message/46079 No, it is actually SEVEN AP scopes. On page 2 there is a Traveler and an 8" prototype Mak-Cass. Whew! It actually might be eight as there is a 155 that Sat, 04 Jul 2009 02:55:04 GMT Rick K http://tech.groups.yahoo.com/group/ap-ug/message/46078 http://tech.groups.yahoo.com/group/ap-ug/message/46078 ... This wouldn't happen to be the 155EDFS that has a 4", or is that a 2.7" FeatherTouch, or was it a 2.7" standard focuser, which shows up on Astromart one Sat, 04 Jul 2009 02:24:45 GMT Rick K http://tech.groups.yahoo.com/group/ap-ug/message/46077 http://tech.groups.yahoo.com/group/ap-ug/message/46077 Ever hear of Thomas Back? Go to Google and type in "thomas back history astro-physics" and whack the enter key.

Lots of options out there. It would be a nice time to be in the scope Fri, 03 Jul 2009 20:34:57 GMT ayiomamitis http://tech.groups.yahoo.com/group/ap-ug/message/46075 http://tech.groups.yahoo.com/group/ap-ug/message/46075 Greg, The actual number is FIVE scopes. I cannot remember the last time, if ever, we had such a concentration at the same time (except for the single listing Fri, 03 Jul 2009 20:30:28 GMT glasspusher2001 http://tech.groups.yahoo.com/group/ap-ug/message/46074 http://tech.groups.yahoo.com/group/ap-ug/message/46074 ... Someone should produce a list of the scopes, whether they are triplets/doublets, years of manufacture, non-ED/FPL51/FPL52/FPL53/ 2.7"/4" focusers, Fri, 03 Jul 2009 19:28:42 GMT gnowellsct http://tech.groups.yahoo.com/group/ap-ug/message/46073 http://tech.groups.yahoo.com/group/ap-ug/message/46073 Jeeze guys there are currently THREE AP scopes for sale on Astromart. There is only one Losmandy mount for sale (one pending). There are NO XW eyepieces for Fri, 03 Jul 2009 18:55:18 GMT Rick K http://tech.groups.yahoo.com/group/ap-ug/message/46072 http://tech.groups.yahoo.com/group/ap-ug/message/46072 ... Looks like the same one to me - same ad copy, same pictures . . .

I finished the "operation" already and yes, there's a slight amount of movement if the cell is shaken sufficiently.

A slight amount of rattle indicates proper spacing, the rattle is only evident while shaking the scope but will not be audible under "normal" conditions.
