I am helping a student, Annet George, who is working on plate solving algorithms. She needs images with a FOV of ~10 deg and that contain some stars with magnitude brighter than 6.

I you have some, please push them on to my google drive .
    - add a directory using your Obscode as the name
    - drop into this directory some (3-10) DSLR images. These images should be debayered. Please include just the G channel.
    - add a note.txt describing the camera that took the images (focal length, make, etc)

Let's help our students!

Thanks,
George

Need to be calibrated?

Hi!

What about calibration?

I've got tons of such FITs files, but the single exposure frames are just teh extraced green channel, uncalibrated. The processing would then calibrate them on the fly and produce a stacked image, on which I then do photometry.

Can you make use of the uncalibrated single frames? Or the stacked , calibrated frames? Or would you need calibrated single frames (I don't have that :-( )?

Cheers

Need to be calibrated? Nah

For this project there is no need to calibrate the images. I believe Annet is working on how to rapidly solve an image to be able to determine a satellite platform's orientation. So images don't need calibration. Send a hand full and she will assess.

Thanks!
George

Images

I have uploaded some G channel images centered around Del Cep. FOV is 10 x 15 degrees.  Hope this helps.

Annet reports that the submitted images have worked well. Thanks!

If we could get just a few more samples she will be good-to-go.

Thanks for the pics!

Annet George sends:

 I just wanted to let you know that I was able to identify a few of the stars in both sets of images that were uploaded onto the drive. I'm still working on improving the accuracy before moving onto the next stage of my project. A big thank you to you and those who shared their images with me. 

Kind Regards,
Annet George
