![]() There's no quoted guide performance here as it doesn't account for that, but useful none the less. It's not quite up to date but illustrates cost in Euros, Payload (max), Period Error (PE) and after PEC training or other control. This list which has been around for awhile lists over 120 mounts stated and independently quoted via owners and forums. It really is down to the build in all cases. Our tuned mounts can run at full payload and still be sub-arcsecond. Your guider by looking at a star dictates sidereal movement, that your motor corrects to. This applies to any worm-driven EQ mount, and should typically be set up slightly east-heavy to provide the mount with an attitude of a controlled fall, so that the RA motor is dictating that precise movement. The common rule of thumb is to take off 1/2 to a 1/3 of the stated maximum payload of the mount, if you're astro-imaging. Everything comes into play, for long exposure - Polar Alignment, Balance, Guide setup, backlash even voltage! That's a dedicated 13.8v/3 Amp supply for you EQ6'ers by the way, not a laptop adapter. If you're guiding or just tracking within or under your limits of seeing, then you are doing really good. ![]() If it's 0.3 of an arc-second or so off, that isn't the time to launch off with a flurry of forum posts or lawyers letters to fix it. On a good night, it should be in the realm of what you see in the tables. So, if your mount doesn't do as stated, check your set up first. But before you beat up on your dealer/manufacturer for supplying a lemon of a mount, and it is statistically likely it won't be, it's down to you to demonstrate it as fact. Yes, you should also get what you pay for.Īll the information supplied is independent, real-world data unless stated. With guiding, some mounts are more equal than others. Primarily, it's all about how it's assembled and designed. This is where it gets a bit fuzzy but I'll simplify where I can. Oh, it needs to do it with your telescope of choice, DLSR or CCD, guidescope and guide camera. Pretty much any well set up EQ mount that can guide via an ST4 port 'should' guide when properly set up down to circa 2-3 arcseconds, which discussed elsewhere is enough for longer exposures under UK skies. Now let us manage a little expectation here and a disclaimer. Top of the tree are the Paramounts with 7 arc-seconds RMS (☓.8 arcsec) across their range. Most people guide though with these mounts though. The claim is that this figure is the true mark of the potential of a mount from a quality perspective in terms of build and assembly, and that less mounts don't make the grade. Is it that easy? Of course not, this is Astronomy! I have included the native periodic error too, as this is causing the most consternation amongst some owners. It makes it easier when making decisions about which one to buy, or whether to tune your mount. Not just hypertuned mounts (as no other tuner seems to publish any data for comparison to stock mount on this scale.), but ALL equatorial mounts and compare them online. ![]() We also have our own in-house custom Test Rigs that can very accurately measure the unguided tracking rate of any mount to 0.001 ArcSecond, which means we can also record the micro acceleration/decelleration of lubricants, stiction, motor tracking and encoder performance over time, compared to 100% of Sidereal Rate. You can do your own research, but none of this is skewed. This is independent data unless specified. I try to update at least once or twice a month, to refine the data and add to it. Disabled clock function in idle connection.If you want to know how good our mounts are compared to everybody else's you've come to the right place.
