Hi, After 3 unsuccessful days attempting to locate Comet Encke near perihelion (due to scattered cloud) I finally succeeded this morning. Unfortunately, I did...
My sincere thanks to Reiner who noted that f/number may not play as important a role in comet imaging as theory would predict. So I did the experiment on New...
... Terry - Your observations are in very good agreement with a sighting communicated to me recently by Alan Hale. He reports spotting 2P/Encke visually at...
compliments for the result of the enterprise! Have to have a really good sky to succeed in photographing a comet at only 5 degrees on the horizon! Very ...
Mike, You are right in that they are single unguided exposures, but my mount is by no means good or well set (I don't think at least). It's made easy in this...
DJ, I'm hoping to do lots of 35mm telephoto & wide field images of this comet when it gets bright... very much looking forward to it. Thing is I've never had a...
Hi Denis, Thanks for your reply and the images, much appreciated. I will try some more with the original files. I usually export the fit files to 16bit TIF...
... Q: Why are we using "track and stack"? A: To increase the SNR on the tracked object, no matter if we want more SNR for getting better astrometry/photometry...
Hi Reiner, I do not quite understand your objection to co-registering on the comet nucleus with a centroid. The nucleus has excellent SNR in single frames. I...
Hi, ... I try to use software which works on any comet and not software which works only on bright comets. It is the same as using standard filters instead of ...
Thank you Reiner. Now I can finally see it for myself. They said they could see 5 jets coming out of "caverns" or "sink hole" surface features. I think the...

Hi all, When will the other images be made available? How do these images compare to the images of Comet Borelly taken by the Deep Space 1 spacecraft? Discuss!...
I am trying to figure why or what good it does to image a comet in such bad viewing. The only reason I can come up with is to make sure it is still there at...
If you look for a database whether to be able to find images of the last years, I recommend you this link http://comete.uai.it/page4.html , where present 1382...
Dear list, this is a short notice to let you know about a new group especially devoted to Comet Images founded by Mike H. The description reads: "For the...
... Do you excuse but don't I understand, if the data, of that an idea can give as him is developing the comets, do they have to go on the list CometObs, the...
It is indeed going to be quite difficult to "discuss" (comets-ml) the morphology of a comet (CometObs) and then compare its evolution to that recorded on film...
Hello all, please let me clarify something: The new list is mainly intended as a buffer for all the "notofication postings" which only say that there is a new...

Maik and all, At the moment T7 is a moderately bright object and there are 5+ image link notifications per day during dark and grey time causing at least as...
Hello all, well, what a nice beginning of 2004. My desk is loaded with work, my family asks for my presence and I happen to have started another "much ado...
Hello Maik.... I really do not believe that any of this is a case for "flaming." Nor reason for.... But there is merit in being able to discuss cometary...

Good Morning Maik, It makes perfect sense to me that one site should be devoted to stricking up real conversations that might boarder on debates about comets,...
Maik - As far as I am concerned, the path you have already proposed is the best and most proper one to follow. While it is interesting, and can be important,...
Members. Please let me take a minute to say a couple of things. First, the idea for a seperate board for images was not Maik's idea but mine. I enjoy...

Dear all, inspired by the recent discussion about comets in literature I would like to add the comet of 1811 to a presentation I show at various places since...
