Interesting. I’ll try to compare to my own similar utility. LN ... From: Julio Castellano [mailto:orodeno2@...] Sent: Monday, January 31, 2005 3:51 PM ...
I have not downloaded astorb.dat for a while. When I did last time, the NUMBER of asteroids compared to mpcorb.dat was different. I am not sure what you mean...
Sounds logical. Since MPC uses different criteria, would they (MPC) consider observations identified by Lowell but not them as 'not needed'? MPC, after all, is...
They are 'osculating' elements but the orbit that they are "kissing" at the MPC is the N-body perturbed orbit only for special objects or those that have an...
I think that in general objects that are at a priority from HOP would probably not be found at the MCP as no observations needed unles they had just been...
I just checked the Lowell 'CRITLIST'. While their criteria for inclusion in the list are very reasonable - perhaps more so than what MPC uses for a subset of...
Hello, ... That's the question. I enjoy very much CCD observation, when I select my targets the question is "is the target interesting?" more than "is the ...
Thanks to all who replied to my question though a bit off topic in this list, sorry. Still interesting how different approaches are managed by seasoned ...
... What settings are you using? Then first time I tried it, I wasn't concerned about the type of asteroid, as long as measurements were needed, so I left the...
Thanks for your help. I have to look what I entered for the 'asteroid selection'. I believe I put some number (6, I think) in the 'inner planet crosser'. Will...
I am looking for keen and committed amateur astronomers to take part in an exciting new astronomical project. You do not need to own your own telescope to get...
Hi group. What Martin does not tell you in this message is that it will cost you $20 per hour at least to be in the program. Let's see $20 X two nights per...
I was curious but also a bit suspicious when he first posted this on MPML, so I checked his website, and I agree it appears to be an attempt to sell scope...

I am looking for a maximum of three more keen and committed amateur astronomers to take part in an exciting new astronomical project. You do not need to own...
Hi everyone, I have to admit a huge lack of experience and feeling completely stupid. I can't get my first image to work in Astrometrica (something I blame...
Since you're on a known star so the pointing isn't in question, the next thing to check is all the image scale (including focal length) and orientation...
... I always recommend that for new users. Set the "number of stars" for the reference star match to zero, and the software will ask for a manual match. Note...
Thanks to both of you for replying.. I haven't spent much time trying a manual match, I will do that. The star field looks vaguely correct in that there's a...
Given that matching the catalog stars to the image is a very common issue (and not just for beginners, but for anyone changing telescopes/CCDs) it might be a...

Virually any scope used for asteroid astrometry is going to be computerized, so what I do if I've made a major change to the imaging configuration, and now...
So, I have tried several manual alignments of the Pollux FOV and a few other heavily populated star fields centered on known stars of about mag 8, still no...
First The f/6.3 focal reducer give that reduction only at one reducer to focal surface distance aprox 105 mm separation if my memory is correct. So to start...
... I assume that almost everyone that steps into astrometry has a number of deep sky images, and these would be a good start. I prefer images of Galaixies, as...
... Ah! suddenly the light bulb goes on! Set the rotation angle to 180° (with a reasonable margin of error), or move to the northern hemisphere, whichever is...
12 inch Meade 200LX-GPS Aperature = 304.8mm Focal Length at f/10 = 3048 mm Focal Length at f/6.3 = 1920.4 mm Focal Length at f/3.3 = 1005.84 mm Arc sec/pixel=...

Expanding on my earlier response... ... about ... this. ... I am 100% sure that west is west. But is it left or right? Since you're down-under, you probably...
John, Thanks for that - You are right, saying "west is west" is rediculous - that was a typo sorry, I meant to say "west is left". I'm going to read your...
