Folks I'm starting on the astrometry learning curve and would appreciate some advice. Please be gentle ;-) Having been CCD imaging for over three years now,...
Dia duit, ... Go to MPC webpage, click on "How do I report material to the MPC?", then click on "Observation format" and then on ""Roving Observer" format. Or...
... Yup, that's the one I got predicted too. See below. However the time of "1991 Nov 27.44795 UTC" for La Silla can only be wrong. At 1991 Nov 27.44795 UTC...
The following stuff is kind of redundant since Reiner provides a lot of info. Since I sent it privately (??) or it disappeared in the Bit Bucket in the Sky,...
Please don't be so pessimistic. From MPC own statistic here (http://cfa- www.harvard.edu/iau/special/AmateurDiscoveries.txt), one could easily see that in the...

With 11" I can get bit beyond mag 18. 19 is way beyond my reach. I wonder how many of us 'true' amateurs here have 18" scopes capable of astrometry. Beyond my...
... Peter Birthwistle in Great Britain regularly gets amazing results using "track and stack". It would take some extra time for each object, but 19th is...
I use a 12 inch Meade LX200 at around f/6 and an ST-8. I take two hour runs of 5 minute images on each search field. Each 5 minute shot goes to 19th mag. or...
... Since the surveys are set up to find NEOs, we don't go back and cover the same parts of the sky. Getting a second night on a main belter is not a priority,...
Something to try. As I write it I do 3 min exposures for 2003 PZ7 (nominally mag 18). With autoguide 5 mins is feasible. Thanks for a the tip. I am going in...
Dave, In order to qualify for an observatory code you have to submit observations of asteroids which have well-known positions anyway. The aim is to ensure you...

Now there is some real science if ever I saw it..... Now we probably will have to add that to the NEO list and issue some Torino number that that. Clay ... Dr....

Yes but it can be very efficent especially with NEOs moving at a few arcsec a minute. When the optimal exposure is 40 seconds or longer and digitization and...
