Hi All, I receive the message "calibration was not succesful" using occuRec v3.3 BETA software and I wonder how reliable is the video recording time of that conditions and how shall I fix it? Thank

Jan Manek All Messages By This Member #253 Hi, are you sure you have an NTSC camera ? I would asume as an European user you have a PAL version from some info off the screenshots. So the problem may be with the USB grabber settings. jan ? ______________________________________________________________ > Od: "Astropriorat" <info@...> > Komu: [email protected] > Datum: 21.04.2022 11:20 > P?edmět: [OccultWatcher] "Calibration was not succesful" > Hi All, I receive the message "calibration was not succesful" using occuRec v3.3 BETA software and I wonder how reliable is the video recording time of that conditions and how shall I fix it?

Astropriorat All Messages By This Member #254 开云体育 I bought the camera from a UK dealer and wasn't aware of the NTSC fact until later. Anyway I understand that British and US colleagues have this system and can naturally work on occultations with the OccuRec, yes? Thank you Jan!

Jan Manek All Messages By This Member #255 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. ? jan ? ______________________________________________________________ > Od: "Astropriorat" <info@...> > Komu: [email protected] > Datum: 21.04.2022 13:57 > P?edmět: Re: [OccultWatcher] "Calibration was not succesful" > I bought the camera from a UK dealer and wasn't aware of the NTSC fact until later.

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.?

Jan Manek All Messages By This Member #257 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. ? jan ? ______________________________________________________________ > Od: "Astropriorat" <info@...> > Komu: [email protected] > Datum: 21.04.2022 22:40 > P?edmět: Re: [OccultWatcher] "Calibration was not succesful" > 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.

The computer OS is WIN7 Pro Looking into the VTI-v3 seems also settled for NTSC, please check the attached image. As an alternative the IOTA capture 2.2 software has been installed and seems to run fine. Any idea for fix this issue? Thank you Joan
Ted Blank All Messages By This Member #262 The picture shows a VTI that is set to PAL mode. ?(The label on the circuit board is reversed.) ?Off is PAL, ON is NTSC.?

Astropriorat All Messages By This Member #264 The switch has been changed according to the previous post by Ted but the problem continues. Same message of calibration not succeded. Regards Joan
Tim Haymes All Messages By This Member #265 Joan,? Just some thoughts on the matter:? The calibration works best when the frame edges are clear, so it should be performed on a field of stars. I say this just in case you are are trying to calibrate on a dark field, when i don't think it will work.? I have fallen into that trap and been advised.? ?Also 4 frames is x8 on the WAT910HX - again something else to be aware of and another possible trap for newcomers (like me).? Tim
Astropriorat All Messages By This Member #266 开云体育 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!

Tim Haymes All Messages By This Member #267 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
Tim Haymes All Messages By This Member #268 And to add, i would use the maximum gain of 41dB.? I expect you have the automatic camera gain and exposure settings set to off.? ?There are recommendation on the use of WAT-910HX on the IOTA occultations? groups.io? ?which i suggest you join if you have not already done so? ;-) Clear skies? - Tim (Oxfordshire, UK)
Astropriorat All Messages By This Member #269 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. -------------------------------------------------------------------------------------------------------------- Some words to add, correct or erase for above? I'm trying to understand video astronomy concepts (not easy by now). Thank you for your patience! Joan
Tim Haymes All Messages By This Member #270 开云体育 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.?
