Set Zero Position - if the mount goes to an incorrect Position because it's lost the setting for the stated reasons, you can carefully return the mount to the correct position and Set that as the Zero Position. The system for calibrating the zero. official website and that any information you provide is encrypted I made index marks on the RA end DEC housings so I have a control possibility. How better you can set the better the alignment stars are in or near the center eyepiece or camera. Accessibility If . Epub 2015 Sep 14. After moving them you can use single axis master and with the indicator change master position to the last known position. Top Spinal Cord Inj Rehabil. PZ-S10A. Add to basket. You may have to reverse the mount on the tripod and use the low latitude positioning of the countrweight bar to achieve this. 1. Obviously, it's the starting position of the mount, with counterweight straight down. That depends on the mount's starting position, which is why I want to control the starting position. Phys Ther. In response to "I think you are confusing" no, I'm clear on what star alignment does. in mount's handcotnroller should be go to zero position and search zero position. It evenly distributes the force and stress across your whole body. Sign up for a new account in our community. If you get reasonably close, then plate solve and synch, you will be fine. The Zero Position reference will be an undefined value after firmware upgrade, or it may lost during power outage or HC battery replacement. Take care of Nanaimo. If you want your mount to to go zero position - press 'go to zero position'. Please re-enable javascript to access full functionality. Is "zero position" the position in which the mount found itself when it was powered up (as with Celestron), or is it a position that is stored in memory? I do always clear the aligment data and set the zero position overnew , every time I use the IEQ30 pro. That operation will put the mount in the correct starting position (within half a degree or so) no matter what position it starts in. I have recently bought an iOptron GEM45 (from FLO) and I am a bit mystified by the Zero Position. 2. Down Side Adjuster Windage CW. My zero position used to be cw-bar horizontal with the weights pointing west. Before starting any session I always 1) search for zero position as the first step and 2) always check if the mount has correct time and location. The easiest way is to level both axes as good as you can with the counterweight-bar pointing west. That is do the "Calibrate Zero Position" without entering any value/offset? Finally, set zero position a second time. But some nights I like to take a tour of the sky without imaging for a change and a 3 star alignment is a must if you are using your hand controller for roaming around and getting your targets spot on. If the search string cannot be found, the result is zero: if the FROM clause is present, this applies only to the section of the source string being searched; if the REPEAT clause is present this applies only if there are insufficient occurrences of the string. correct starting position, counterweight down, dec parallel to polar axis, and sets that I even use this zero-position system for polar alignment in day time (for solar viewing) or in places where I have no view on North. ], [no - if you press set zero it will use that saved position if you ever then chose goto zero position and that might well be wrong if you managed to save it in the wrong place! Most of the code was cobbled together to get the Nema 23 steppers working the way I want. Zero setting device - Made of hardened steel - With spring-loaded sensing surface - The device is placed on the workpiece - The machine spindle is used to move the cutting tool onto the sensing surface until the pointer of the dial gauge is at zero - The distance from the cutting tool to the workpiece is exactly 50 mm - For determining the . A one star alignment fixes it. In the past I would power my mount, use the hand controller to position the mount in the zero position and then power the mount off and back on. [yes. and no depending on the position you stored or has been stored], [I think you are confusing zero position and the star alignment routine - just because its at zero it doesn't mean that a slew to an object will be totally accurate - that comes from a star alignment - so when zero'd and you slew you will still want to align on the star accurately as possible using 1-3 star alignment/sync to target as I find they are not accurate until thats done ]. Would you sill use"Search Zero Position" followed by "Calibrate Zero Position" (optional step of the same item)". Graphically, the zeros of a function are the points on the x-axis where the graph cuts the x-axis. One point though. I found a thread on cloudy nightshttps://www.cloudynights.com/topic/513870-cem60-search-for-zero-and-other-stuff/in which someone took his CEM60 apart and found a combination of pins and Hall Effect sensors that control the Search Zero process. Thanks, Waldemar. You can use this function to set the zero position reference. After the 3-star alignment I could goto DSO's and the Moon, but I couldn't goto any planet. Either write down the joint position or take a back up before disconnecting, summary DG will have the joint position in it. But I do want to understand all the things this mount does. That is what it is for, in simplest terms. Edited by mannys, 16 September 2021 - 02:56 PM. So I have no idea why this works for me and not for you Everytime I use my mount it is on exactly the same position. (2) "Set zero position" redefines zero position until power off. I'm pretty sure the next 2 stars were better centered. sharing sensitive information, make sure youre on a federal ], [yes there is an internal peg that it looks for - when you hit search zero position it will slew around the zero position until it finds the peg and then will settle on it no further adjustment to do - you can also store that if you want it - BUT depending if the RA /DEC was actually in the right position and aligned to a CW down position at zero the CW/dec might not be down/up - if it misaligned then you might need to also unlock the RA and DEC and realign them so when at zero position it is CW down / scope up position BUT you can also store your own zero position so if you own an obs and want to align to your own zero position you can store you own as well or use a saved park position as well ]. from this point on, use the keys on your hc to adjust your alignment. The Zero Position is defined as the telescope being on top of the mount head and pointing to North Pole, with CW shaft pointing to the ground. Pressure relief for your muscles and joints 3. eCollection 2021. You currently have javascript disabled. If you loosened the clutches for what ever reason, just tell the mount 'go to zero-position' and use the markers to set the RA and DEC position back to zero. Finally, adjust the control to . If the crank is at timing mark and either head's arrows--> notches appear to be off, then you have the whole head out of time and you have to re-time the timing belt. Clinical implications of scapular dyskinesis in shoulder injury: the 2013 consensus statement from the 'Scapular Summit'. So I think the above is misleading, or I am confused, and I just am taking a cloud break from accidentally finding out. A Pilot Study. Careers. (3) "Search zero position" takes the mount from any position to a fairly accurate [it has all it needs built in - so yes you're right - see below], [No - its the stored position which might not be CW down etc depending on what has been stored previously - happens all the time on our observatory CEM40! I had read it, but sadly I hadn't understood it - hence the request for guidance. All our Tele Radio, radio remote controls with an emergency stop have this function. Find out information about zero adjuster. By using this site, you agree to our Terms of Use. First, select the range you wish to use. Michael. It is good to know that the name 'infinity knob' comes from the fact that at 0 voltage, you have 'infinite resistance'. If you plate solve an object before imaging it, do you still have to set zero position? But if you want the initial slew on alignment to get you close, I think you need to be at the intended zero, not just anywhere you want. Zero adjuster | Article about zero adjuster by The Free Dictionary. It is 30' from where I sit, so I haven't pursued the problem further. Press ENTER to confirm.

You can also use it to point your scope to a lightscreen or EL panel for making flats. it would hunt, the sensors would find the index markers and then it always put the tube and counterweight bar off to one side or another. Yesterday all my alignment stars on my CEM 60 were by the same amount off. Select Search Zero Pos. and the mount will start to slew slowly and find the R.A. and DEC position to set the mount to the Zero Position. The encoder in the servo 1FK7060-XAF7X-XFXX (6SL3055-0AA00-5 Mxx rotary, [2051] 2048, 1 Vpp, A/B, EnDat, multivuelta 4096) To verify the . Thanks for helping out! I hope to hear from people who have figured out exactly how iOptron mounts work. What I wrote here is what I find out on using the mounts. To me it is still fuzzy how to set the zero pos on a IEQ30 pro correctly , but in practice I don't have much issues with the goto evenso. CEM40 for me. You can use this function to set the zero position reference. When I hit 'D' the motors run their routine. I should add that I'm not new to computerized mounts -- I've been using them for 19 years and have written about how they work. In the AccelStepper class reference you will find the setCurrentPosition function. I have not tested that thoroughly -- more experiments tomorrow. Or, zero position to your finder scope in polaris, if not polar aligning. From there you start your alignment and verify, not the other way around. The zero position serves only one purpose: to establish a reference for the first GoTo when star aligning. groundFungus October 24, 2018, 1:31am #2. These mounts should at least have set zero position function. The .gov means its official. Do all iOptron mounts 'have search for zero position' function ?

I still have my HEQ5-Pro and have had no alignment issues like I have with my CEM40. 2021 Sep;24(3):156-165. doi: 10.5397/cise.2021.00248. It provides an easy way to change the phase relationship of a drive component and the shaft. Park position is where the mount is set to a designated position when turned off. Copyright 2021 Stargazers Lounge Front Bioeng Biotechnol. But I suspect iOptron has something better up its sleeve and just hasn't documented it very fully. Personally I use plate solving so don't worry too much but I search for zero - store that but only once in a blue moon - as normally i just use the find zero and the last thing I do after I have mounted everything and polar aligned is before I walk away from the scope is to ensure i have the goto zero command entered so I am sure it is actually aligned CW down / DEC aligned so my first plate solve slews are mostly accurate. Answer boxes. I'll do some experiments to confirm this. Set the latitude / altitude adjuster to 0 degrees. VOLT - OHM - Millimeter Always rest the function switch at 250V AC, if an OFF position is not available in the instrument. Unlike my Celestron mounts, my iOptron mount doesn't have index marks to define a precise starting position.
