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.
Hi Mabula,
its me, again :P.
I have a little Problem. I book a few Sessions with the Chilescope. Hell, that are damn good Pictures, but the Sensor itself and the Calibration is very hard to get. There are many Stripes and Columns, Bad Pixel etc.
So i give the Calibration a try - more then once. But i have a Problem with these Stripes - see the Picture.
On the left Side is the uncalibrated Lightframe, on the right side the calibrated one. Im using Cold Column 9 and Hot Column 9. The Black Line is gone, the white Line is still there, but on the right side from the white line, is a blurry line. But on the Lightframe, there is no line to remove.
Thats on OIII and HA. I dont manage to remove this Line without blurry the other Area.
Please Help 🙁
Greetings, Markus
Dear Markus @detoxx,
Before performing cosmetic correction, it's preferred and much better to make sure that the data is calibrated with a matching masterdark, a Masterflat and a Bad Pixel Map. Have you done this?
If you apply a Bad Pixel Map, it will always be better than a cosmetic hot pixel correction.
A matching MasterDark should really help with correcting bad columns, any remaining visible bad columns then can be corrected cosmetically.
Do you have calibration data, like masters for your raw frames?
kappa 9 for the columns is very low... that will usually not correct everything, best to use a value between 5-8. The lower the kappa, the more will be corrected, so be carefull, if you set it too low, too much will be corrected.
Cheers,
Mabula
Hi Mabula. Yeah i know, i always use a BadPixelMap for all Sensors. But on Chilescope, the Sensor have huge Problems with these Lines. And these Lines are not Corrected with the Darks or Bias. I do this several Times.
I remove the Lines manually in Photoshop, not a big deal, but it takes Time.
Thanks for your reply!
If they are not corrected at all with the darks, it might be that the calibration data is not right somehow. I would also ask the manager of the telescope in that regard.
