ASCOM pulse guide settings. ST 4 Cable or ASCOM Pulse Guiding? As you may be aware, there are two typical methods of There is no performance advantage in using an ST4 cable over using ASCOM pulse guiding, as the. The program can tell the mount how much to guide, instead of a fixed guide pulse. Pulse guide (at current rate): d=n,s,e,w nnnn=time in mS (from 20 to 16399mS). An overview for those who have never guided and some tips for advanced users who already know their way around a guiding graph. of the correction pulse, so allowing a large correction in one axis may delay a necessary correction in the other. ) Since the accuracy of a pulse duration is 1 ms, sending a pulse whose duration is less than 10 ms could result in errors larger than 10%. Besides the fewer-cables benefit Joel mentioned, another slight benefit of using ASCOM for guiding is that for most modern ASCOM driver /mount controller combinations (including AP CP3) the guide pulse timings are executed by the mount controller: phd2 says “guide north for 10 milliseconds” and the mount does so, precisely timing the 10 ms. This allows fractional arcsecond commands to be sent to the telescope, which is necessary for guiding at typical resolution levels. Enable ASCOM Pulse Guiding and verify that SideOfPier is Pointing (ASCOM). This method of guiding requires no additional interface boxes or cables. This telescope control system has been installed on scopes as small as 3 inches, to as large as 41 inches! It connects to 2 servo motors with integral encoders, and 2 telescope encoders. I am writing an ascom driver for an arduino powered telescope. It is said that pulse guiding (with an ASCOM compliant) equatorial mount results in improved guiding accuracy. Other than ST4 type of autoguiding, EQMOD also provides the “PulseGuide” Method where the correction commands are fed directly through ASCOM. We are able to connect SiTech to Maxim DL 6 using the Observatory Tab in Maxim DL. One of the benefits of using EQASCOM is that correction commands and be sent from the guiding application through EQASCOM to the mount using the EQDirect (or PC direct if using the Syncan) serial interface. Auto-guiding is the method by which a secondary camera is set to lock on to a target star, and the idea is – if it notices that it moves slightly, it nudges your mount back to where it should be (and these should be minute micro-movements in the realms of sub-pixels). ) (I sometimes use ST4 as shown in my screen-shot. PHD2 is downloaded via https. I think if what the video says is true for ascom as well, then if I'm pulse guiding I should give a much longer calibration time to move the star more pixels. Equally the implementation of ASCOM Pulse guiding is driver dependent and there may be differences in the methods of implementation between different vendors. One option is to have PHD send ASCOM pulse guide commands to EQASCOM which in turn will apply the necessary corrections using the serial link. Other than ST4 type of. Re: Auto-guiding: ST-4 vs pulse guiding and other technical guiding questions I don't mind looking funny working with the tools I have got and no EE background. Provides position readout, slews, side of pier (where appropriate), and pulse guiding among its basic capabilities. Fine, but it did for the last year. Find details of the Industry Canada IC application for this product here. Some cameras may be connected directly to the mount by means of an ST4 cable, so guiding corrections are sent by means of electronic signals to the mount controller board. PHD stops guiding when a pulseguide command is sent. YOU can write your own code and import it into this software. It combines home security with automation features that let you manage, monitor and modify your home from almost anywhere. ASCOM: Connecting the computer to the HEQ5's serial port with usb to serial cables (which I still need to find). Gear Connections.

Mission-critical communication addresses the essential elements of keeping patients and caregivers connected, and staff coordinated with other team members. It derives its name from its most distinctive feature, pulse guiding, which can improve unguided tracking. If you are using an ASCOM (or 'aux' ) mount interface, your calibration will be adjusted automatically and you can simply resume guiding (assuming you haven't also rotated the camera or focuser). PHD2 says the ASCOM SkyWatcher Mount does not support Pulse Guiding. It is said that pulse guiding (with an ASCOM compliant) equatorial mount results in improved guiding accuracy. Theoretically, guiding through a serial link to the mount (usually via an ASCOM driver) could make the correction more quickly, but this is generally not done. The ST-4 Port is easy to add to "low cost" motorized mounts like the EQ4 or EQ5, and the operation requires minimal modification to your shiny mount. Direct pulse dithering (APT Pulse Dithering) for self-guided solutions. 25 Siderial rate, or x0. Set the ASCOM Pulse Guide Setting to show a tick in both the RA and Dec boxes and set the display to x0. A bounding pulse is a pulse that feels as though your heart racing. Through that connection SiTech can control the camera to do a single photo init. , I've always had a tough time figuring out which way North is in the guide frame, whether an axis is. The key is in the implementation. However, EQMOD also supports ‘pulse guiding’ which is a more advanced form of control that sends a packet of data to the mount containing two parameters, a ‘direction to move’ and a ‘duration of movement’ command. Regrettably, the plug-in doesn’t support pulse-guiding nor does it use ASCOM (or INDI) standards. Some people think serial port guiding, particularly “pulse guiding,” a feature of some ASCOM telescope drivers, is better since each guide message going to the mount contains not just the direction the telescope needs to move, but also for how long. This can be measured using the tools found in the PHD2 guiding software, mainly in the total RMS error reading. Here are the authors reasons for using pulse guiding vs ST4 guiding. ST 4 Cable or ASCOM Pulse Guiding? As you may be aware, there are two typical methods of There is no performance advantage in using an ST4 cable over using ASCOM pulse guiding, as the. Field Value.
