Repost with corrections: Maxim V.4 with SBIG ST-2000XCM color camera

#13623 Sep 5, 2004

Hi,

Anybody out there know if Maxim V.4 supports the new SBIG ST-2000XCM

color camera? I'm having the following problem when trying to process

the single-shot, full color, LRGB images taken with this camera:



In Maxim, Calibration fails with a pop up window that doesn't contain

any info on the error, just an exclamation point, when trying to

calibrate the full color single shot images with darks and flats

taken with the same camera.



The only way I can get calibrate to work with these images is to

first, extract the individual LRGB layers for the raw image, and do

the same for the flats and darks, then do calibration for each

extracted image, using the extracted flats and darks for each

color layer separately. Then I can do a color combine and do final

processing from there. A lot of work, to be sure!!! I also tried to

calibrate using the single-shot, LRGB UN-extracted flats and darks on

each image that WAS extracted down to it's raw color layer, and again,

calibration failed. Maybe Maxim can't figure out how to apply a full-

color, single shot image (even if it's a flat or dark) to a single

layer, extracted image during the calibration process.



SBIG's CCDOPS software DOES support the ST-2000XCM camera, and has

added a couple of menu options for it, but the processing is so nice

in Maxim, I would like to just stay with it for shooting and

processing the pics, if I can just figure this out on the processing

end of things!! Any help here would be greatly appreciated!



Thanks,

Wade Van Arsdale

Wade

Maxim v.4 does support the st2kxcm. I'm using this camera with a

cge14/ao7 and having no problems processing in maxim. I'm calibrating

with master dark frames only(no flats yet). The various master darks

are selected in the set calibration dialog box. Then the raw

image/images is/are calibrated using the calibrate or calibrate all

command under the process tab. I've never had trouble with this

calibration step. The images being calibrated are the single shot

LRGB data as it comes from the camera. I generally combine these

calibrated frames and then color convert using the convert RGB

command under the color tab. Not sure why your having problems but

can assure you that maxim does support this camera.

Hi Steve,

Thanks so much for your help!! I think it is mainly my inexperience

processing single-shot color pics that is most of the problem here.

I do see upon playing with it some more today, that the single shot

darks ARE noise-reducing it properly...it is the single shot FLATS

that aren't working right. They don't cause any error messages in

the calibration runs, but they are lightening the final calibrated

frames in a way that cannot be fixed with the screen stretch option.

There seems to be MORE noise, not less noise present, after using

the flats in calibration. This could have something to do with my

flats though...they were a little on the bright side. I will need

to re-do them just to see if that is the problem.



I wonder if I could just do a histogram stretch on the flats to

darken them down some, THEN use them in the calibration process??

Will try that later tonight. I can also say that if you don't mind

jumping through the hoops of extracting the LRGB layers and

processing everything separately, then re-combining them, I am pretty

pleased with how the final product is turning out with this method,

but whew.....that is a lot of work to go through!!!



Thanks again, and I will definitely try your suggestions.



Best regards,

Wade

Hi,

To complete this thread, it did wind up being mostly user error on

my part. Doug at Maxim was kind enough to provide some tips on

processing of single-shot full color pics from the ST-2000XCM camera,

and these tips, combined with what I discovered on my own, have made

the processing steps much simpler, with a better-looking finished

product:



1) To registered owners of Maxim V.4, be sure to check for the latest

update patches in the Help tab inside Maxim's main window. (I

was two versions behind on the patches, and this did cause part

of the problems I was having!!).



2) Process all FLATS (flats only, NOT darks), with the "Kernel

Filtering" command, set to the "User Filter" option. Click the

"Set" button and plug in the below listed values, then apply

this to the flats and re-save the flats (NO pre-calibration

processing is needed on the Darks):

0 1 1

0 1 1

0 0 0



3) Setup Calibration Wizard to calibrate with the MEDIAN method, using

the Darks and Flats, pointing the Wizard to the appropriate

folder(s) where the Flats and Darks are saved.



4) Open ALL the raw, single-shot, full color images at the same time.



5) Perform a "Calibrate All", based on what was setup previously in

the Calibration Wizard.



6) Perform an "Align" on the raw, calibrated images, then a "Combine",

to produce ONE, final monochrome image that is now ready for final

color processing. You can use the "Sum" method for many stacked

exposures of shorter exposure length, to increase the S/N ratio,

or the "Median" method of combining, if your objects are already

pretty bright on the raw frames, and show good fine detail.



7) Perform an "RGB Combine" on the aligned and combined image to

convert it to one, full-color image.



8) On the full-color image just produced, experiment with the

following commands to get the picture like you want it:

a) Color Smoothing

b) Color Balancing (if necessary)

c) Adjust Saturation, (if necessary)

d) Unsharp Mask, to sharpen the image resolution

e) Screen Stetch, to set contrast and brightness of final image.

(Doing the above steps IN THE ORDER listed is working best for me

right now, until I gain more experience with it).



9) If converting to a JPEG file, use the "Crop" command to reduce the

image size down to around 640 x 480 or less if the pic is going

to be sent by email, in order to reduce the file size, and select

the "Auto Stretch" option in the Save dialog box, or the image

will likely appear too dark in JPEG format.



The above is not meant to be portrayed as the ONLY way to do this

with the ST-2000XCM, but is merely a starter set of instructions that

worked well for me, to get you up and running with processing using

this type of camera. Many of you, I'm sure, are far advanced beyond

these steps in final processing.



Again, thanks Steve, and also Doug from Maxim for your help.



Best regards,

Wade Van Arsdale

#13649 Sep 7, 2004

In the "Files" section, I have placed two M13 photos taken with the

ST-2000XCM camera. First one is first-light, processing extracted

LRGB layers, processed each layer separately. The 2nd photo uses the

processing methods outlined in Post #13647 here.



I would greatly appreciate any tips or suggestions anyone could give

me on what they do with this same single-shot camera to get good

looking pics.



I'm much more pleased with the 2nd photo, but would really like to

hear from anyone who may have some tips on using some different

techniques to bring out the most from these single-shot color cameras.



Thanks,

Wade Van Arsdale

#13657 Sep 8, 2004

Wade,



I was under the impression that one should convert from the RAW

matrix to a colour image *before* aligning/combining, otherwise the

shifting of the images will disrupt the ability to convert the matrix

into a correct colour image?

Hi John,

I'm so new to this single shot color thing, I will try just that and

compare. Will let you know and repost the tip sheet if it works out

that way. Thanks for the info!!



Clear skies,

Wade

#13662 Sep 8, 2004

Hi John,

I tried it the way you suggested, but the color just doesn't look

right to me---very blue. I will have to play around with it to try

to figure out how to balance it better. Doug at Maxim has concurred

you are correct. Thanks for your help! Any suggestions on how to

"un-blue" the best way (Maxim V.4.03) would be greatly appreciated,

as I am still learning and probably will be for some time. I've

been used to doing mono for so long and LRGB separate layer combines,

it's a new way of thinking for me altogether!!



Links to the test images (these links will probably be broken, and

will have to be applied manually, OR, you can just view them in the

"Wade Van Arsdale" folder here on the group):



1st: LRGB layers processed separately:

f1.grp.yahoofs.com/v1/kDo_QZJpkznQhhSveH_PNi1t__QpEvcbEYfqnMeGg

SSgA5PeWvWP1pAj2_hvRQQuYgRxgDpmvGIcEQoxIrPMjOzIoSA/Wade%20Van%

20Arsdale/M13.jpg



2nd: Align/Combine done FIRST, then RGB Convert done:

f1.grp.yahoofs.com/v1/kDo_QRtN5L_QhhSvQISTQ7g3y7Wkv8bkeBgBDWuE7

Ypoo8kRpnC4TGS92NS434cfjrzbWiEIyDDQ0iFf0D6wTHLUx_U/Wade%20Van%

20Arsdale/m13.jpg



3rd: RGB convert done first on each calibrated image, then Align/

Combine done last, before color processing options were done to

finish it out:

f4.grp.yahoofs.com/v1/kDo_QSWVrQzQhhSvkJb2lBhKXGUIokLwvEATeH6_3

4aune8_UzRhc1NzgMGHDGPpELAmyYbZ6fHMqotbKg_jEAe2RUs/Wade%20Van%

20Arsdale/M13-b.jpg



NOTES:

#3 is what the experts at Maxim recommend. Mine tended to come out

too blue like this, but I was able to attenuate most of this, and

will probably do much better at this with more experience!!





Cheers,

Wade

#13663 Sep 8, 2004

****************************************************************



CORRECTED steps to process single-shot color photos with the

ST-2000XCM color CCD camera:

---------------



1) To registered owners of Maxim V.4, be sure to check for the latest

update patches in the Help tab inside Maxim's main window. (I

was two versions behind on the patches, and this did cause part

of the problems I was having!!).



2) Process all FLATS (flats only, NOT darks), with the "Kernel

Filtering" command, set to the "User Filter" option. Click the

"Set" button and plug in the below listed values, then apply

this to the flats and re-save the flats (NO pre-calibration

processing is needed on the Darks):

0 1 1

0 1 1

0 0 0



3) Setup Calibration Wizard to calibrate with the MEDIAN method, using

the Darks and Flats, pointing the Wizard to the appropriate

folder(s) where the Flats and Darks are saved. You can also

experiment with Sigma Clip or SD Mask as your calibration method, to

see which gives better results.



4) Open ALL the raw, single-shot, monochrome images at the same time.



5) Perform a "Calibrate All", based on what was setup previously in

the Calibration Wizard.



6) Perform an "RGB Combine" on EACH calibrated image to convert them

all to full-color images.



7) Perform an "Align" on the RGB converted images, then a "Combine",

to produce ONE, final full color image that is now ready for final

color processing. You can use the "Sum" method for many stacked

exposures of shorter exposure length, to increase the S/N ratio,

or the "Median" method of combining, if your objects are already

pretty bright on the raw frames, and show good fine detail. Also

though, experiment with the Sigma Clip and SD Mask methods, to see

which gives the best-looking results for your combined image.



8) On the full-color image just produced, experiment with the

following commands to get the picture like you want it:

a) Color Smoothing

b) Color Balancing, and/or Color Adjust (if necessary)

c) Adjust Saturation, (if necessary)

d) Unsharp Mask, to sharpen the image resolution

e) Screen Stetch, to set contrast and brightness of final image.

(Doing the above steps IN THE ORDER listed is working best for me

right now, but this may change as I gain more experience with it).



9) After final color processing is completed, if converting to a JPEG

file, use the "Crop" command to reduce the image size down to around

640 x 480 or less if the pic is going to be sent by email, in order

to reduce the file size, and select the "Auto Stretch" option in the

Save dialog box, or the image will likely appear too dark in JPEG

format. *NOTE*, you may have to use Screen Stretch to make the final

FITS file look a little "overexposed", before cropping a portion of

it out. Cropping sometimes seems to reduce the brightness of the

cropped image after steps 1-8 have already been performed. At

present, I don't know how to stop this from happening, but, usually,

the effects are very slight, and can be fixed with the above Screen

Stretch option, before saving the final version as a JPEG file. Also,

you can use the "Resize" options INSTEAD of Crop, and NOT have this

effect to deal with, but you will lose image scale with this as not

only does the final frame size decrease, but also your image size.

That's why I prefer the "Crop" option over resizing the whole frame.



The above is not meant to be portrayed as the ONLY way to do this

with the ST-2000XCM, but is merely a starter set of instructions that

worked well for me, to get you up and running with processing using

this type of camera. Many of you, I'm sure, are far advanced beyond

these steps in final processing.



Again, thanks Steve and John from the user group, and also Doug and

Chris from Maxim for your help.
