Actually, it was me!  I was jazzed at the first imaging results I got from my 6" f/10 Newt this summer.

Hi Ray,

I think that thread was started by me with this image taken on my  

C9.25 & TIS DBK 21A F04.AS in 2008;

I`d be interested to see any experiments Terry has carried out so far  

too!

Hi Terrence,

At the risk of sounding sarcastic. What? is the your best Jupiter  

image so far. I'd really like to have a look :o]

Alan, I am slowly getting all the pieces in place.

I have a Homeyer's Motorized Filter Wheel on the way and all of the  

other items you suggested in the list below.  Lets hope I can  

become a competent planet imager.  Lucky for me I did not have to  

move.  (-:

Thanks for the help.

Hi Terry,

I sent a response to one of your earlier posts from vacation but I  

don't think it made it through. Milton brought up the issues of  

working with an analog camera and the compression pitfalls that  

limit the results using IMovie for planetary imaging. I'd suggest  

going this route:

DMK21AF04 firewire camera (60fps - 15fps on 41 series camera is  

too slow for Jupiter)

IR blocked RGB filters Astronomik work well)

color filter wheel - manual rotation is fine.

Astro IIDC for camera control

home in Florida (you have that, lucky dog)

The last time I used my astrovid for imaging was at the Venue  

transit:

it works, but a digital firewire camera will remove many  

limitations and let you get the best from the fine seeing at your  

location.

cheers,

Alan

Tim, I am not familiar with the camera you used - but assume it  

is a color firewire camera.  I notice they have them from 80 fps  

down to 7.5 fps.  I assume the higher frame rates are needed to  

freeze the rapid rotation of Jupiter, something like a 9.5 hour  

day.

But I would appreciate hearing comments on which cameras are best  

for which applications.  I am also interested in inserting a date/ 

time stamp on the individual frames to support photometry.  Is  

there a system for doing that with firewire?

I've just started stacking the movies, and I shot a bunch of  

movies. This was the first one processed.

For some reason, Astro IIDC is showing 0 frames at the 75%  

confidence level, with all 1001 frames represented by a single  

spike. So for now, until I figure out why, I'm letting it stack  

all the frames (the seeing was pretty good, after all).
