Re: How to use a planetary camera for occultations
Here with two GPS: the DCDTRAKER software from (tools)GENIKA which recovers the pps and NTP Meinberg signal. Nothing more to say about precision. You need the right serial cables to use it correctly

Re: How to use a planetary camera for occultations
A PC with good live timing cannot record a video with good recording timing I agree because of the latency it creates, there it is not the same thing there is no random timestamp it's all digital PCs

Re: How to use a planetary camera for occultations
I have seen discussions of this NTP PC timing issue posted offline. The issue is not that the observer can get good accurate timing at the PC, the problem is the timing at the PC is not the timing at

Re: How to use a planetary camera for occultations
RE, One last important thing for my GPS to work well, you must only keep the GPS satellites (American) you must deactivate all the others in Ucenter (Ublox) otherwise it does not work.

Re: How to use a planetary camera for occultations
Good morning, I continue to monitor NTP Meinberg and I find that the more I use it, the more precise it is. I don't have to wait 1 hour for stability unlike NMEATime2. NTP Meinberg is operational

Len, I don¡¯t see that anyone has responded to your request. One good starting point is the IOTA website: IOTA (occultations.org) <https://occultations.org/> for everything/anything Observing Basics

Re: How to use a planetary camera for occultations
Hi Steve Russell - I have been recording occultations for about a year now and I am currently using a LED flashed into the optical path as you mention.??? I have a GPS module that generates a PPS

Re: How to use a planetary camera for occultations
Hi Graem The LED is flashed into the optical path at the beginning and end of the observation. You can use the flashes to work out the capture delay of your camera system and the offset of your PC

Hi all, I have some interest in observing some of the occultations and would like to find a source for learning the technique and terminology, like the "mas"? and cord. Fly with Pegasus Len

Hello: I am not clear on one point - are you planning to shine the LED from the GPS module into the telescope with no gating (I.e. it could flash while the occultation is in progress?)?GraemSent from

Re: How to use a planetary camera for occultations
In the configuration file there is the offset adjustment in "Timer2 0.00".. which must be set to zero then a SER must be carried out at 1000fps by reducing the format with SharpCap. You open your SER
