Trying my hand at Webcam Imaging

[leon]

Hi all

The next clear night i'm going to try some Webcam work on Saturn.
I have the Phillips 840k, unmodded.

Now iv'e never done this before so i would like to ask this...... :D

Do i use the 12" SCT or the ED80, and do i go prime focus, or use 26mm EP, or 2x Barlow, or both in either scope.

Or is there a better combination. :)

I understand Mike is right up there with this, so Mike :help:

Thank You.

Cheers Leon :thumbsup:

Go prime focus with the SCT Leon.

The ED80 is too short a focal length for imaging planets.

OK... no-one else other than Mike answer dear old leon's questions:lol:

:lol: ok stop yer yappin astro pooch! :P MOOO!

go the 12 inch cause you will get a longer focal length for one and increased aperture for more detail :thumbsup:
even if the ed80 could get the same image scale the aperture would hold it back.
oh and prime focus. :)

[matt]

Yeah.... what cow-boy says:):thumbsup:

[leon]

Sorry Matt,

It wasn't supposed to sound like it did, i'm sure all you guys are equally qualified to answer my questions.:thumbsup:

Cheers leon

[leon]

Thanks for your info guys, much appreciated.

Cheers Leon

No apology needed, leon.

Just having a lend. Good luck with your imaging and keep asking those questions.

the bovine and yapping pup are always happy to help :)

hey, post your results too. youd be suprised what you can learn fromthe experts when they see your image :)

another sugestion, i am not sure what fl your scope is but if the seeing can handle it throw a barlow in there too. it will increase your scale further :)

[leon]

Yea Ving i was considering that, if i get any reasonable results, i will post them.

Cheers Leon

12" + 2X barlow (technically called negative projection, check out this link (http://www.iceinspace.com.au/forum/attachment.php?attachmentid=20720&d=1165965132) but substitute the slr for a webcam)

Thanks Paul, looks fairly basic, all i need is the smoke to clear tonight.

Cheers Leon

Definitely go with the 12", and start with prime focus. The image scale won't be huge, but it's a good start to make sure your tracking is working well.

Once you've had some experience capturing a few avi's, stick in a 2x barlow, 2.5x powermate, 3x barlow, 4x barlow or whatever you've got for increased image scale.

Processing is a whole other story.. read my articles for a bit of help on that and then ask questions!

You should also try imaging the moon as i have found this good practice re focus, centering of image etc

Wish I could get over to your place Leon. :( Rotten shift work!

We could both Toucam image and learn from each other.
