Hi Danny, Last winter I re-mounted the LX200 on an MI-250. I've been tempted to pull the AO-7 off for a few weeks but, as you note, it's hard to put it aside. ...
Data from multiple nights is, after all, just data - no difference from having gathered it on a single night. Seeing can change from minute to minute, hour to...
I wound up writing the software for the SBIG seeing monitor. SBIG did the camera control code and algorithms for the most part; I did the user interface and...
Ron, thanks. I see in the package now that I have it, that you did write the software. I am going to install it this weekend. I think focusing it may be the...
For anyone who missed it, here was first light with the M25C! Per Bud Guinn, this was 2x2 binning of the one-shot with excellent result! As I'm 'scopeless' at...
Thanks,and yes Randy- 30' subs. I have consistently gone 15-20' w/ the H9C and felt that the lower Ha response of the M25C should get 30' for really rich...
Dear Colleagues, The impact of the SMART-1 is due to take on 3 September 2006 at 05:41 UT, according to the best data now available, with an uncertainty of...
I am considering two options for mounting a guide scope for my AP 155 EDFS. Option 1 is with traditional guide scope rings that allow adjustment of the guide...
Warren, I missed your original post, but caught Randy's praise of your image. Very impressive - and with the Mini Borg 45ED. Proves the images is not just the...
Valmir, thank you for bringing this event to my attention. Others may have been aware of it, but this is the first I have heard of it. What strategies should...
When imaging an object using RGB filters, is the goal to achieve similar background ADU counts for each color filter? ... [Non-text portions of this message...
Hi Don: I use a guide scope with rings that allow adjustment, and flexure is minimum since I really tight up the rings to the scope. I used to guide with a ...
The past few weeks have been busy setting up and testing new equipment. Along with the new AP1200GTO mount and ST10XME camera, I've mounted an AP guide scope...
Hi All; This is my first attempt on a Bi-color image (Ha, OIII). It is NGC 6888. Many thanks to Steve Cannistra for giving us his procedure. Meade DSI II Pro ...
Hi Don, My experience is that a quality, 3-point ring system should be adequate - particularly for a relatively short focal length imaging system (1150mm)....
Not exactly. The actual goal is equal signal to noise ratio (S/N). This does not always equate to equal signal, since the noise can vary. For example, if your...
Hi Don, What I have found to be very effective is to rigidly mount the guide scope, using non-adjustable rings, dovetail plate, or any other inflexible...
Frank, As an example, if you were imaging a red nebula you certainly would not want to match the background counts in the other filters. The background is...
Hello all. I am hoping someone can give me a tip to improve this image: http://brianclever.smugmug.com/gallery/1533746/1/82041487 specifically how to eliminate...

Not really. Background counts vary via sky conditions (light pollution) and filters used. For example you may have a much lower background adu with the blue...
Brian, I'm not sure what you're asking. The posted image of the Lagoon is very small, and it's in a fairly dense star field, so if should look "dusty." --Mark...
Brian, I don't understand why you feel the image needs "dusting" (I assume by this that you mean "smoothing"). A little noise in an image contributes to a...
I have followed this thread for a while without commenting. But, I do need to make a comment at this point. I have had many years of experience with external...
Hi Adam, I think we all agree that background adu is not relevant in terms of color balance (except for tweaking the black points in each channel so that the...
