Some ETX users have sent me examples of their astrophotography. If you have some examples you would like included here please send me a description of how you made the astrophotos and a copy of the images as GIF or JPEG files (due to internet email gateway issues, please send only one image file per message). Send to firstname.lastname@example.org. Alternatively, if you have created your own web page with your examples please let me know and I'll include a link to your site.

Please find attached a picture of the comet Linear 2000 WM1
made with the ETX125EC and a digital camera Olympus 2020Z with 40mm
eyepiece projection. No guiding.
For my home position of 48 North and 16:23 East, i think that was the
last chance to picture the comet at an altitude of 21 degree above
2 little tails are visible, a lot of fog of the horizon right of the comet
I added 9 images - each one exposed 16 seconds.
Feel free to place this image on your ETX page. Thanks for running
your page as the best ETX info repository and experience exchange i have
seen so far on amateur astronomy.

The Comet LINEAR shot was taken on July 14/01 @ 0405hrs with a Canon Ftb and Konica Centuria 800ASA film. I used a 135mm lense @ f/2.8 for 4 min. and was piggybacking on a Meade ETX 90 telescope. The comet was at mag. 4.4 and in Pegasus at the time.

On July 13th this year i tried to picture the Comet Linear C/2001 A2 with
the ETX 125EC. It was the first chance here in Austria
after weeks of bad weather and full moon during good weather.
I used the Olympus 2020Z which i cooled simply between the shoots in the
deep freezer for 3 minutes to
minimize thermal noise which came up soon at outside air temperature of 25
Each picture was exposed 16 seconds with 40mm Eyepiece projection.
Neither visually nor on the pictures i could see a tail at that 'late'
But the movement of the Comet is easy visible if you compare picture ~8
(00:22:52) and picture ~9(00:41:37).

Last night (19th July 10:30pm PDT = 20th Jul 5:30 GMT, Seattle) i went
out with my ETX90 for a third evening's attempt to find Linear S4. I
used Sky&Tel's coordiates (
www.skypub.com/sights/comets/0007linearS4.html ), panning from
the 20th's toward the 21st's coordinates.
And there it (maybe) was, a faint smudge forming a very acute triangle
with a couple of other tiny stars, near the predicted spot. I popped in
the Barlow for an effective 13mm eyepiece.
And, as i continued to watch it over the next twenty minutes... it
moved. The triangle gradually opened up toward isosceles-ness.
Definitely a comet!
There's a 5kbyte sketched gif attached to this note. North is
up, west is -right-, as seen through the eyepiece.
This shows something i keep forgetting, and happily rediscover... even
though we're watching things happening over (pardon) astronomical
distances... many of them change in short human-attention-span terms.
A favorite of mine is to watch the dance of Jupiter's moons... if you
watch for half an hour or so, you'll frequently see them come and go
from behind or before the planet, change their relative positions, etc.
(i won't mention the fight i had with creep-after-beep...)
Mike here: yes, I know, it's not a photo but a drawing...
