How to Submit Images to the Comet Observation Home Page

What to Submit

This home page is happy to post images provided in electronic form of any comet past and present provided the following conditions are met:
The person submitting the image is the one who took it. Do not send images taken by other people.

The image is provided in either .gif or .jpg format.

You provide the complete details concerning the image (telescope used, CCD used, time of exposure, length of exposure, etc.). This description should be provided in a separate file, if possible. Write it up as you wish it to appear. The more I have to edit, the less stuff that will be posted.

Please include your e-mail address in your description. This will make it easier for someone interested to use your image, to let you know about it and ask permission.

Submit only one .gif or .jpg file per comet per night. This .gif or .jpg file can actually include several images of the comet on one image frame - there are several examples of this on the image page. There are exceptions (of course): if the second image is processed differently (e.g., is in false color) or if something interesting is happening. For faint comets (that might not show much detail), it is acceptable to submit two images on the same night to illustrate motion.

The image is worth posting - you can see the comet!

Make it clear that the Comet Observation Home Page has your permission to post the image!
If you are in doubt, ask...

How to Submit Images

Images can be submitted either by e-mail or regular mail. E-mail is by far the recommended choice.

Images can be e-mailed by using uuencode (standard on UNIX systems, I believe) or by MIME software. For PCs, Gordon Garradd provides the following instructions for downloading uuencode/decode software for a PC:

ftp oak.oakland.edu
login anonymous
password (your email address)
cd simtel/msdos/decode
binary (to get a binary rather than text file)
get uuexe540.zip ( about 40K in size)
enter (keeps the file name)
quit

Then use PKUNZIP to extract the decoding and encoding .exe files

If you must send the images on floppy disk by regular mail, please e-mail me and I will provide a complete address.
