Re: "Calibration was not succesful"
Hi,
I use gain at 38dB, as I "feel" that noise increases with the
final counts up to maximum substantial.
But that's maybe only "question of taste"...
best regards, Bj?rn.

Re: "Calibration was not succesful"
Joan, this a good summary.
For your notes i would remove the "SHUTTER= adjust..." because the
exposure is summarized correctly in the *Notes section at the end.
It is possible to use dark video or dark frame subtraction in
TANGRA , but this is not a typical procedure.? If you have a new
camera, there shouldn't be many hot pixels to worry about.?? Hot
weather will introduce more noise it is true, as the camera is
running about 10 degrees above ambient (im guessing a bit here).
For video data submitted for publication and research, its
possible to convert AVI or AAV to FITS, and then some additional
image procession is possible.
If you are new to occultation work, the next step is decide how
you will introduce the frame time stamps but i expect you already
have this set up.
The IOTA-VTI is one possibility, or in Europe the
GPSBOXSPRITE3.? Familiarity with OccultWatcher is desirable of
course, as it will provide the asteroid predictions of most
interest to you.?? If you are observing Lunar Occs, you will want
to establish the Coordinator for your region so you can report
timings.
I would suggest contacting? /g/IOTAoccultations
and someone will reply.?

Tim,
In the meantime I'm waiting for a window of good weather I have
compiled a series of indications from different sources about
video astronomy occultations and I would be grateful to know your
opinion.
--------------------------------------------------------------------------------------------------------------------------------
For asteroid occultation's it
is recommended to use the initial camera settings described
below and control the camera with two manually settings: The
"SHUTTER" exposure and the "AGC" gain, according to the
magnitude and conditions of the target object.
WAT-910HX/RC EIA? Initial
Camera Settings
To access
settings; Press "enter" and select "Exposure" at the small
camera keypad
?
Settings for
Occultations are:
SHUTTER = adjust between x2 to x256, Exposure
Index, 1/50th, 1/250th and shorter.
AGC: Set it to maximum of ?41 dB ?or ?adjust manually
between 6 to 41 dB.
?
Most (indeed all)
advanced setting should be turned off for occultation video.
The most important controls set to OFF are:
SENS UP: auto
exposure OFF
SHARPNESS = 0 [
default is 4 ]
3DNR : Dynamic
noise reduction OFF
GAMMA: Set to 1
IMAGE REVERSAL is
a useful function if you are using right-angled viewers.
?
?
* NOTES:
- Use Dark Frame
subtraction, also possible on the fly.
- For Asteroid
Occultations, use x2 (0.04), x4 (0.08), x8 (0.16), x16
(0.32). Longer exposure will be needed for faint object or
smaller telescope aperture.
- For focusing
on the Moon (lunar Occultations) use EI, and then change
to 1/50th. or x2 for timing.
-In longer
exposures “hot pixels” shall appear.

Re: "Calibration was not succesful"
Joan,
I think the problem is the dark image.? The frames need to be exposed.? ?Hristo has some notes here:?http://www.hristopavlov.net/OccuRec/IntegrationDetection.html
The WAT910HX/RC settings are the number of fields (not frames)?? x2 fields = 1 frame, and x8 fields = 4 frames.?? So when the calibration asks for 4 frames then set the camera control to x8.?
Im sure someone will jump in if i'm incorrect.
Tim

Re: "Calibration was not succesful"
Yes, I was doing the calibration on dark field with the dome closed, just as an initial testing before the real occultation.
This multiply factor of 2x for this camera means that "normal" shutter steps from 2x to 256x are in fact 4x to 512x ?
Thank you for your help!

Re: "Calibration was not succesful"
Hi,
?
the EIA corresponds to NTSC (US standard). So if everything in the chain is set and work as NTSC (which under all provided info seems to be fulfilled), calibration should work in Occurec if you have the latest version 3.3.1.
?
Older version v3.3.0 (2019-09-13) states (beside other things)
- Fixed problems with integration locking after scheduled and manual recording
?
Otherwise I'm at the end now with any other explanation, sorry :-(
I don't have now any usable HW available to test the situation.

Hi,
The exact camera reference is a WATEC-910HX/RC EIA? and to be sure about it today I sent a question to the UK dealer.
Interesting what you mention about your A/D converter, hummm...
Please, keep in mind also about the rol that VTI have? This unit automatically will switches? between PAL and NTSC input but for proper operation the format chosen must be selected via? a DIP switch and must be the same as the format used by the external camera.?

Hi,

I would be surprised if you really have NTSC version camera. What I had in mind is a problem, which can be introduced by the USB A/D converter.
?
Example : I had a PAL camera, however my A/D converter on first capture insisted that it has on input NTSC signal (not PAL) and the output was always flawed by having NTSC framerate (and sometimes wrong videi linear dimensions). I had to force some capture settings (I was using VirtualDub) to convince the grabber it has an PAL input. Thenafter everything was OK.
?
I think if on input is indeed PAL signal with 25fps, but grabber signals it is NTSC with 29.97fps, you can't get correct calibration.

Check and experiment.
