UPDATE FROM MABULA

I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.

 

Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.

 

APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46.  Before I release it, I will make sure that everything is working properly and then I will release it.

Hello all 🙂 

Well, rather than bothering Mabula with emails, maybe I can share here this problem I face as a beginner....

I am trying to process my first Lights (acquired a month ago, thanks to this great weather...). I work with CCD AP 5, MaximDL, Focusmax and TheSkyX Pro in remote. The camera is an ATIK 4000 M. 

I used the routines of CCD AP to make darks, bias and sky flats. It turns out that the Lights and FLATS are 2042 x 2042 pixels wide, but the BIAS and DARKS are only 752 x 580 , hence the following message from APP when trying to Calibrate :

"Bias Calibration is not possible due to different frame dimensions" (cf. pic linked).

I could not find a setting in the CCD AP option tabs for the size of the calibration images, so I guess this should not matter. Do I miss a step in the calibration process ? Or is it truly a problem at images acquisition ?

TYVM in advance 🙂

JBG

 

PS : sorry for my poor syntax 😉

BTW , I posted a similar question on the CCD Autopilot forum :  http://ccdware.infopop.cc/eve/forums?a=tpc&s=290100098&f=9997083106&m=1117092986&r=1117092986#1117092986

@jb-gayet,

I can't see your topic on the CCD Autopilot forum, because I don't have a login unfortunately. Did you get an answer there?

I can only assume this might has to do with binning somehow of the sensor of your CCD camera, or some settings in the capture software.

To be able to do proper calibration, the calibration frames need to be the same size as the lights, because calibration is something that works on pixel scale to do it properly.

If there was binning, like 2x2 I would expect the frames to show the 2x factor. So for the 2048x2048 frames, the calirbation frames would be 1024x1024 for instance.

The fact that the frames are 752 x 580 really puzzles me, because the aspect ratio of the frame is different as well.

I would be curious to know the asnwers on the CCD autopilot forum.

Kind regards,

Mabula

Hello 🙂 Well the solution came by the previous owner of the camera who used CCD AP5 too and told me that the sole solution he could think of was that the dark had been obtained via the guider camera (ie Lodestar X2) and he was right 🙂 the image size was the exact size of the Lodestar 🙂 

 
The question for me was then to understand how such thing  happened and I finally found out that in MaximDL, the "guiding camera" box option was checked to "1" (and not to "2") which means that, for maximDL, the guiding camera was the ATIK 4000 and -I guess - the main camera was by default the Lodestar. Obviously this information was sent to CCD AP 🙂
 
 
So, you were right to be puzzled by this weird ratio 😉
 
JB

@jb-gayet,

Thank you JB, that explains a lot  😉

Still laughing. Sounds like so many mistakes I've made..... oops forgot to check there.
