Greetings, To start the New Year off I imaged Saturn very early this morning. I have a good AVI and am still playing with it now. Posted in the bnd1430 folder...
Hi Brian - Great shot !!! I am also glad you posted exposure information with your photo. It really helps other newbees like me to see what can be done with...

Greetings again, Since I am sill on vacation I have time for late night imaging, so here is another Saturn of which I like, 3-Jan in my bnd1430 folder! And to...
Hi, there. I seem to be struggling more than I thought with the NexImage. I've uploaded a picture of Jupiter to my photo folder "Ellandee." If any of you get...
Brain, Wow! I don't know if it is the contrast booster or not, but I like the filtered image much better. It appears much sharper to me. Great image(s) of...
Hi Rick, It looks like you either have gain or brightness very high. I would start by setting your brightness to 50%, gamma and gain at 0% and FPS's as low as...
Rick, I have not shot the moons of any planet yet. That said, here is what I think. To shoot the moons and the planet at the same time is not generally ...
On Tue, 03 Jan 2006 16:31:42, "rcole_sooner" ... Another way to decrease the brightness is to increase your image size. With a 2x barlow you'll spread...
Hello! I'm hoping that some of the experts of the long exposure Mod (including the man himself, Freddy Diaz) could help me with a problem I'm having. I...
Thanks so much to all. This is just the exact detail of advice I needed. Sounds like I turn a lot of things down to where the image is actually pretty dim on...
Mike, On my mod, I use the AMP-OFF line to control the shutter line, that in the case of the Steve´s mod, must be controller with a Manual switch. So, if you...
Richard, As others have stated, you are overexposing the image, if you use the K3CCDTools software to capture the AVI, you can use a level meter, in my case I...
I have reservations about installing WcRmac to shoot in RAW mode, has anybody had any problems with it at all? also the Celestron site says to download macros...
Jup, I tested this already and reloaded the Celestron factory setting because I couldn't get good results using the RAW mode. I tested it in the house in...
Thanks for the suggestion Freddy. I'm not sure when I'll be able to try it, but I'll let you know if it works. Should the "turn off amp" button be clicked...
Brian, There are posts about "F20 gets you to critical Nyquist sampling". I don't know what scope you are using, but for a f10 scope a 2x barlow is required to...
Howdy, Note that the magnification won't change the screen-door effect in the preview window. The problem is that most imaging applications don't know how to...
Russell, Get your Crayons out for me because I missed the "Nyquist sampling" posts and it wasn't covered in my Barnyard Engineering course! Are you suggesting...
Well, from chemical instrumental analysis, I know that the Nyquest frequency involves a critical sampling rate. It involves sampling the signal frequency (a...
Brian, Whew, asking me to explain Nyquist sampling, is like asking a three-year-old to explain brain surgery (or to spell it). For some reason I can't search...
This is from wolfram.com In order to recover all Fourier components of a periodic waveform, it is necessary to sample more than twice as fast as the highest...
Here is my understanding of this stuff... From "Handbook of Astronomical Image Processing" by Richard Berry and James Burnell, chapter 1: (abbreviated) The...
My limited understanding of the Nyquist limit: My 10" LX200 f/10 is capable of resolving details down to approx. 0.75 arc-seconds. (Dawe's Limit?) This is a...
There we go -- that makes some sense. The new link works fine, thanks. Nice image too. Note that you do need that barlow in order to go above critical ...
... If you think spatial frequency you have the idea. The intensity of the image at any point is f(x,y) and f(x,y) can be expressed as sums of sines and...

Yikes, That sure set off a flurry of posts and that's quite a got of good info back. So much, my brain nearly exploded! Since I still have it all loaded up in...
