Interesting Phenomenon.

Posted By Derrick Lipinski

Hello all. smile

Not quite sure where to put this as it's not really deep sky or anything.

Coming back from the lake early one Sunday morning (2:00 am) in early July, I noticed some interesting cloud formations in the north. Being at 53d 30’ latitude (Edmonton), although the sun does set, there is a dim twilight in the north throughout the night so it never really gets completely dark in the summer. Not too great for observing deep sky stuff, but does allow for some pretty cool phenomenon. These appear to be some fairly high-altitude clouds reflecting some of the sunlight from far over the horizon. I believe the term for this would be “noctilucent clouds”. It was an eerie kind of light, sort of like aurora, but more like a huge spiderweb in the sky.

Sorry it's not really "Deep Sky".

Clear skies smile

ToUcam Basics?

Posted By Derrick Lipinski

There are probably many sources on the web
dealing with how to use a web cam. I'm not sure
there is an actual book or text specifically aimed
at astrophotography, as I don't think the designers
of these cameras envisioned they would ever be used
for that purpose.

If you want to see some really phenomenal planetary imaging
using a web cam, I would encourage you to visit Thierry
Legault's and Antonio Cidadao's homepages. Talk about
High-Res planetary imaging, well... visit their sites and
see for yourself:
http://perso.club-internet.fr/legault/
http://www.astrosurf.com/cidadao/
These sites are fantastic resources.

Another one to check out is Ed Grafton's page at:

Hope this helps, Steve.

Have fun.

A truly spectacular image Mark!

Are you using any kind of autoguider
as your stars are pin-point.

Nice job.

Hi again Mark.

You mean to say that this image was taken with a
common digital SLR??

Do you have any other images you have taken with
this camera?

Once again, my compliments on a great image.

Derrick.

toucam frame rates

Posted By Derrick Lipinski

Wow. Great info Eddie!

This must be the web page you're referring to:
http://www.pk3.org/Astro/astrophoto_vesta_pro.htm
The tests were done using a Vesta Pro, but I would
think the results could be the same for the ToUcam
as well

I have been doing all of my video capture
at 30fps, but by looking at the tests, I'll
have to see what kind of results I can get @
5fps.

Thanks,

Derrick

Another Saturn From Michigan

Posted By Derrick Lipinski

That's awsome! Looks like it could be a storm.
It would be great if you could find some HST or
other shots of the same time to confirm. Very
nice work Joe.

I woke up late this morning to a beautifully
clear sky... ARRGHHH! Too late to get the
telescope out. Saturn must've been spectacular.

Raw stacked image? Finally Saturn

Posted By Derrick Lipinski

Hi Wes.

I doubt I would do a better job, but I'd be interested
in the unprocessed stacked image, more so as a guage or
benchmark of what a good raw stacked image should look
like.

Thanks Wes,

Still cloudy in Edmonton...

Derrick.
