Re: (IAAC) Obj: STF 517 - Inst: Celestar 8" SCT, Fork mount
Hmm, I had been taking something for granted
here I think,
I use Skymap pro to plan any observing
sessions which has such info as it uses the WDS Catalogue, and I would guess
that other such programs do as well, I figured that perhaps you had access to
something similar. It was the recorded separation that I meant, e.g if your
observation said "this pair was pretty tight, but it was split at 500x" it would
be interesting to know what the sep was but I can of course just use Skymap to
find out. Thanx for the reply, and sorry if I made an error!

Depends on what you mean. If you are referring to a personal
measurement of mine of the separation, I must confess that I always do not
attempt measures. Sometimes the pair is too tight, faint, etc. Sometimes, I will
admit, I don't want to bother and just enjoy looking at the pair. If I do
measure the separation, I almost invariably put my results in me
notes.
If you mean the PA as listed in some published list, that would be
possible. Most of my double star measurements are for one of the "33 Doubles"
observing projects - see http://whuyss.tripod.com/33.html.

William, I always enjoy your double star observations, but they
would have an increased relevance if you could include the seperation in all
the records, in this way I can compare instrument performance etc! what do you
think?
