For all you who got the 11 CD-ROM set from me, it would be good if you could run a check on Zone600 in Disk 1. This is an important zone, with data for between...
Greetings, I'm a new Astrometrica user and must say I was quite excited to solve a few of my novice images! A couple of questions and a suggestion from a...
David, They may be more competent people to answer your questions but here I go. 10 secs at 2x binning with a SBIG camera should be more than adequate for...
... Which scope are you using? I trained the PEC on a 12" LX200 (trained with my autoguider, much better than manual) and that allows 1 min unguided ...
John, Could you give me a more detailed idea how you do "autoguider" training for PEC ? I, also, have a 12-inch SCT and am just being introduced to this side...
... Frank, It couldn't be easier, at least on an LX200 classic (don't know about the GPS). Just set up the autoguider to guide on a star near the meridian* at...
... David, You'll probably get a wide range of answers on your first question but you can sort through and get a good idea about what can be done with various ...
... ...and if you have only 3 ref stars you will get residuals of dRA 0.0" and dDE 0.0"... Even more nice! :) You need *a lot more* stars than 4 for a...
This brings up an interesting question - - to me, anyway. Is there minimum number of reference stars or, when one is using USNO A2, a minimum proportion of...
Hi Bob, I'm rather new at this endeavor, too, but I thought the idea was to match the time of the integration to speed of the object and the angular span of...
Hi Herbert, hi all list members! I'm now using Astrometrica Win for quit a while with fairly low position failure rates. Many of the remaining failures can be ...
... As Matthias has pointed out, this is not really a nice fit. Compare this with the fit found for the tutorial images that come with the software: There are...
... I am not an expert in photometry. But I think you can not expect to get "perfect" photometry unless you use standard BVR-filters. Magnitudes from a...
Dear Users! I wanted to note that the image of the month for January 2003 is online since yesterday. It's an omage of the TNO 2002 TC302, taken by my friend...
Dear All, and especially Herbert, Happy New Year! I was just reading an article about Johannes Kepler (in Patrick Moore's Sky at Night, vol.4), and noticed to...

Hello John, indeed, Kepler lived and worked in Linz 1612-1626. He finished his "Tabulae Rudolphinae" ephemeris and discovered his third law here. The school...
And I thought Kepler made most of his discoveries in my native city of Prague, now Czech Republic. Well, he at least acquired the raw data (no CCD images then)...
... Thanks John et al for all the replies! I have a C-8 with an MX-716 camera at present. Looks like I get better sensitivity by binning and that puts me at...
... Yes, this solved it!! You'll be reassured to know that 43 Ariadne is right where it should be. (At least it was a week ago) :> ... It's more to help...

Reiner: Actually exposure corresponding to passage of one FWHM is not actually the optimum. Exposure times equivalent to passage across one pixel is also...
Bob: The particular example you give isn't likely to be very conclusive with respect to what is the optimum exposure time. The lower bound on the optimum would...
... David, thanks for your reply. 5 local (general area) stars with mags of 16.5 to 17.2 show FWHM of 7.1, 7.8, 7.2, 7.2and 7.6. The object itself was not...
Bob: Your FWHM for stars near the object indicates that trailing is not apparent. But there still is nothing in the data to indicate that equivalent or better...
