Is there a way to automatically, or batch remove bad pixels from an

existing pixel table in MaxIm rather than having to click 'process' manually

on each image? Thanks.

You can write a simple script or plug-in to activate the bad pixel removal

feature for each open image.

I have written a problem, CalGroups for MaxIm DL 3, which will give you the

ability to do this very easily. It has been in beta testing for a couple of

months, and with some changes in 3.07 of MaxIm DL to accommodate the

program, it is getting close to shipping.



The changes in 3.07 gave me the ability to do some nifty additional things

with CalGroups, and these changes are the main reason the program has not

already been shipping. Here's a list of some of the things you can do with

CalGroups:



* The program allows you to specify bias, dark, and flat-field frames in

groups. You can save groups, and re-use them later.



* When you save a group, it also saves a set of master calibration frames.

It will be much faster to re-use these master frames, than to recreate them

each time as you must do conventionally.



* In addition to calibration groups, the program also supports many batch

operations, including hot pixel removal, sharpening, applying bad pixel

maps, smoothing, etc.



* The program will also automatically combine images after calibration or

batch processing operations.



* The program will include a full online tutorial (in the style of my book),

with lots and lots of illustrations and examples.



I just started testing the program with version 3.07 of MaxIm within the

last few days. I'll announce a beta version of the program and will invite

MaxIm DL users to test it freely as soon as I have cleaned up the changes

related to the new functionality. When the program has been in beta for a

few weeks, and the bugs ironed out, I will be offering it for sale at a

reasonable fee. Those folks who have my book will be able to buy it at half

price. The list price will be $29.95.

A little fast and loose with the spell checker, there. "Problem" is really

"Program," of course, though the potential for humor here is pretty high!

You can also use Ron Wodaski's "CalGroups" utility -- on the New CCD Astronomy web page. It automates the calibration process and allows you to do auto-processing, such as remove hot pixel, flatten background, remove gradient, etc. On a series of images in one operation�� Roth Ritter rritter2@...> wrote:>>Roth Ritter wrote:>>>>�� Is there a way to automatically, or batch remove bad pixels from an>>�� existing pixel table in MaxIm rather than having to click 'process' manually>>�� on each image?

Hi,



Is there a way to use the "Remove Bad Pixels" function on multiple

images (in conjunction with the "Combine" command) ?



It seems to me that bad pixels are only removed on the currently

selected image when I press the process button on the remove

bad pixels screen.



It would be great if I could remove the bad pixels as part of the

combine function when I stack images...

Use the Command Sequence tool.

Hello Doug,



Here's another question along the same vein. From the camera control

window, I can take a sequence of images. I can also calibrate these

on the fly by selecting auto calibration from the settings tab (I

like this very much). Is there a way to also correct bad pixels on

the fly without having to use the command sequence tool or

scripting? It seems to me that most folks will have at least some

bad pixels that they will want to correct first thing. If this

was "built in" by providing a check box and map selector, it would

remove the need to complicate things with the sequence tool or

scripting. While I am very glad you have provided these two very

powerful tools, on the fly bad pixel correction would provide one

less thing to deal with.



Thanks again for a truly great program.



Rich

Well, the problem is there's always going to be "one more thing". It's

a tradeoff between making the program more complicated and providing the

facilities to do things. The Command Sequence tool was intended for

exactly this sort of thing. I'm reluctant to reinvent the wheel with a

single-purpose command. So I'd suggest you make a command sequence that

handles calibration and bad pixel masks, and just run that on all your

disk images.

Is there a way around the feature that only allows the creation of

five different "maps" - if you use several scopes at different binning

you need at least ten.



Any thoughts?

I'll ask one of the guys to increase the number of available slots.

#24151 May 14, 2006

Maxim is fully able to do this job, but I am not exactly sure how to

get it to do a slight variation. Can anyone help?



I have taken a set of 10-minute dark frames (SXV-H9C camera) and

looked at them carefully. They all have some hot pixels that can be

identified visually when I click from frame to frame. In addition,

there are some seemingly random extra hot pixels that may be cosmic

ray hits, in different positions on each frame. I would like to get

Maxim to produce a map of the (consistent) hot pixels without using

the random hot pixels. What is the best way to do this - rather than

me looking at individual frames?



TIA

Lawrence,



A Combine witht the 'Median' output option should give you a new image that

has just the static hot pixels you are looking for as the it will throw away

the random ones here and there, but keep the items that are in every (or

most) frames. Use this new image to make the hot pixel map, then you can

apply the map on your originals to remove the steady pattern of hots that

occurs in every image.



I hope this is helpful,
