I am pleased to announce that Fred Metzler has been added to the list of presenters at the Riverside AstroImaging Workshop for September 21-22, just before PATS. Fred will be going into detail about how a DSLR can contribute to Astro Imaging.

Yes, that is TWO DAYS this year for the Riverside AstroImaging Workshop.

On Thursday afternoon (September 20), we will have an in depth workshop on Image Processing with Tony Hallas. That evening, we will have Tim Puckett present a special "Remote Imaging" session. Friday (September 21) will be group presentations from some of the most impressive astroimagers around. These include Tony Hallas, Mr. Eclipse Fred Espenak, Sky and Tel's Sean Walker, QSI's Kevin Nelson, Canon's Fred Metzler, Tom Bash (working on the general image acquisition and processing), and solar imager extraordinaire Gary Palmer.

Can't make both days? You will be able to register separately or as a two-day package for this. Registration is available at http://patsimage.org/
Any feedback, suggestions, questions, just send them along. Love to hear from you.

For those of you from far away--rooms are available at the Sheraton for a reduced rate......

Hope to see you there.

Kevin Nelson will be presenting a special program on how to get the most out of a CCD imaging system at the Riverside AstroImaging Workshop for September 21-22, just before PATS. Kevin plans to focus on how a CCD system works so that the user can understand better how to capture good images.

I have a ten year old SCT.....Celestron 9.25. The stars at the edge (and considerably in from the edge) are a little fuzzier than I like.

I suppose I need a corrector. I have a corrector/reducer that gets it to 6.3, but want to retain the longer focal length.

Is there a good corrector that is appropriate for this?

Today (September 1), is the last day to register for early bird discount at the Riverside AstroImaging workshop on Thursday afternoon/Friday all day, September 20-21, just before PATS in Pasadena, California.
The presenters include:
Tony Hallas, who will share more of his processing secrets
Sean Walker, Imaging Editor from Sky and Tel
Gary Palmer, solar imager extraordinaire,
Fred Espenak, a leader in imaging eclipses and other syzygies
Tim Puckett, who will tell us about remote imaging,
Fred Metzler, Canon
Kevin Nelson, QSI
Tom Bash, General image acquisition and processing
and
Richard Wright, How to manage an evening's imaging

More information is at patsimage.org

If you cannot make two days, you can still come Friday only.

Hope to see you there.

The Frequently Asked Questions is for asking Frequently Asked Questions.

There are a number of Forums I am not monitoring. I hope they are doing well. I am monitoring this one, and will do my best to keep it within the bounds of what we come to Astromart for.

If anybody has any questions to ask, please do so. But let us keep them related to operating the Forum, about Astronomy, and so forth.

Thanks,

Alex
(And be good.....I have work to do, and cannot watch you while you play!!!!)

I was under (the perhaps mistaken) impression that we can rate users only of we have in fact made a deal with them. That is, we cannot rate people when deal falls through because somebody flakes out or if we do not agree on a price or whatever.

Is that true?

Alex

That happens when your imaging plane (the sensor) is not at right angles to the incoming light rays.

That, in turn, happens when your camera is not flush with the surface of the focuser (because the adapter is slightly smaller than the focuser tube, allowing some wiggle) or because the focuser itself is not mounted flush, or because the tube itself (including the focuser parts) sags.

Alex

Heggie,

I can't quite figure out what you are asking....

I read it that you have a super polaris mount, but that the controls and motors you have running it are those for a CG-5.

If that is the case, I can share my experience trying to get a CG-5 rewired to work with an autoguider. I failed.

I posted requests for information on several forums, I called Celestron, I took the whole thing apart and looked through it, and poked and prodded with a meter trying to figure out what is happening when one pushes a button. I got nowhere, and after all that effort still cannot use the CG-5 with an autoguider--and have been told by Celestron that it cannot be done.

I hope somebody out there has a better answer.

Alex

Mike,

Are you sure that the ST-4 designed some ten or twelve years ago can even spell USB, much less communicate with it?

Alex

George,

try Rivastro.org

That is the Riverside Astronomical Society.

Table Mountain, Wrightwood (near Ski SUnrise) this weekend.
