Mount balance sounds easy, right? Simply set the telescope and the counterweights so that they are well balanced against one another. But this is not enough! For most mounts, being slightly East-Heavy makes tracking better - we'll look at why in this video!
Today, I'm comparing my Canon 200mm f2.8L (mark 1) lens against my Refracting Telescope (275mm f4.5), and see how the camera lens fares when doing astrophotography!
Note that this is just with a single sample of this lens - lens can have a lot of variability. And some lenses are generally better than others and exhibit almost none of the issues I highlight in this video (the Samyang 135mm F2 lens in particular is supposed to be excellent, and my sample of it certainly was).

Good video. Hanging additional weights by a thread is indeed asking for trouble! Have you thought of positioning your three weights with the outer weight (say) 5cm from the end stop and setting the other two weights for a perfect balance but also with a gap between the outer weight and the other two weights? Now you can move the weight out or in to get East heavy on each side of the Meridian in a controlled and quick way e.g. no more extra weights, just a controlled weight redistribution? Simon

After a meridian flip or if I am finished imaging one one side of the mount and want to image on the other side, I simply move one of the counterweights upwards or downwards on the shaft so that the mount is still east sdie heavy, so the OTA will will be heavy on the east side of the mount instead of the counterweights. The trick is to experiment with the counter weight p[ositions *before* you boot up the mount and begin imaging. That way, you will already know which position to move the lower or upper counterweight to. Just simply, carefully, move the weight on the shaft. It's possible you may loose one sub due to vibration but that's a small price to pay. I hope that helps.

Thank you for the great video. I use a Weight Hanging On A String and I’ve never had any problems with it swinging in any wind that I'd consider reasonable for imaging. I have an MI 250 mount that has a 200mm disc as the output of the RA axis. I have a simple flange that guides the string from the circumference of the disc to vertical. I hang about 250g of lead shot in a vial from the string. The weight only hangs down about 32cm. I have not noticed any swing in any winds that I’d consider reasonable for imaging. This gives about 250 Nm (.2 ft lb) of East torque.

Hey Cuiv! I just saw that video, and I may have a solution for you :) What about balancing your mount with your perfect balance method (I'll check that one just after this!), and then add on your shaft a small weight, like .25kg, on the east side. This small weight you want to be able to slide it on the shaft, and also have a small threaded bar sticking out. The idea is to put it on the shaft when the counterweights are eastward, or to screw it on the tube's rings when it's the tube facing east. Whenever you flip the meridian, then you also flip the side you put that weight, and move from perfectly(east)balanced to perfectly(west)balanced :D

Another great video! I've been meaning to ask if your eq6-r pro is easily moved in RA even when the clutch is tight? I see a lot of people having the same question. Mine doesn't seem to ever slip while tracking (most likely due to my super excellent "Cuiv" balance technique!) but it is fairly easy to move when locked. Might make a good video on how to correct sticky/stiff axes and clutch locking adjustments. Thanks again for the great content!

Thanks Jonkjon! I have the same - the mount can be moved even with the RA clutch tight, but it does require a bit of force. It has never been an issue for me, even with a fairly large unbalance. Fixing that would likely involve opening the mount, and I probably don't want to do that!

Excellent video (again) and easy to understand east heavy. You have 3 weights and (I have two weights), I see there is a possibility of adding a small central weight. Slide central weight to be east heavy (clamp with a peg) and later, after a meridian shift, slide it the other way (clamp again). An automatic (manual) solution for "both side" zenith imaging? Knowing the exact balance, of course, provides the option of then becoming east heavy. Perhaps seeing the results between balanced and later east heavy to be "totally" convinced? Simon

Hello friend in faraway Japan I think this is another beautiful one setting but you can go so far in perfection that you get a bit crazy; now I have taken the back lakh out of my HEQ5 and a few months ago also provided it with a belt drive and I do approximate a good balance and have actually never had blurry images even after a meridian flip personally I think that some things are exaggerated but every his opinion of course it is so that it is less noticeable at small focal distances.

Great videos!!! I’m a bit confused with ‘East heavy.’ Other KZbin videos say that East Heavy should be where the OTA (on the East side of the mount) should be heavier, therefore moving the weights up (not down as you suggest)….you can see why I’m confused. Thanks for clarifying.

08:00 I found the same, tested East heavy vs. "perfect" balance, and could find no difference in my guiding numbers with the EQ6R, before or after the flip. I think your reasoning that it is because the seeing is too terrible to see any difference is probably correct. I also wonder how much the weight of the payload makes a difference.

Thanks for another interesting video. Can you (if not done already) give guidance on how tight the clutches on EQ6 and variants should be during use and should the mount be able to move if the clutch is tight but not in use? If so, what could be the cause of the movement or does it not matter because the motor controls the movement when in use. There is conflicting information about how right the clutch should be especially when upgrading from something like a Star Adventurer where the clutch needs to be tight.

I have to unbalance DEC a lot to the south otherwise my PHD2 calibration wont work because DEC cant reach the starting point.

There is a common misconception and has passed into folk lore the drag is from the bearings and poor lubrication and you hear of people changing the bearings and substituting in the latest fad lubricant. Some even go so far as to include ceramic hybrid bearings at great cost which is a complete waste of money since ceramic bearings are no more accurate than conventional steel bearings. Ceramic bearings are only useful when running at extreme speed or high temperature, neither of which applies to a telescope mount. Any post work improvement is not because of the new parts, rather is a result of more careful meshing of the gears. The drag spoken of is drag between the main housing and the combined clutch/crown wheel which is made deliberately close. The clutch thumb screw merely prevents the crown wheel rotating when engaged. While it makes balancing a challenge the de-clutched drag has no impact on the tracking since the crown wheel is essentially locked to the main housing and the worm/motor which is on the output rotate around the crown wheel. Like Cuiv says the accuracy of the gear teeth and backlash free engagement of the crown wheel and worm along with accurate motor speed is what determines the tracking ability of a mount.

I think for EQ6-R it doesn't make much of a difference, because the mount is so stiff. Even with the clutch disengaged there is a considerable amount of force you need to apply to move each axis. iOptrons, on the other hand, are a different story. Perhaps for them an east-heavy or a west-heavy setup would work better.

That's a very good point - the stiffness would prevent the mount from "floating". Oh my, could the stiffness be by design? :D

There is a common misconception and has passed into folk lore the drag is from the bearings and poor lubrication and you hear of people changing the bearings and substituting in the latest fad lubricant. Some even go so far as to include ceramic hybrid bearings at great cost which is a complete waste of money since ceramic bearings are no more accurate than conventional steel bearings. Ceramic bearings are only useful when running at extreme speed or high temperature, neither of which applies to a telescope mount. Any post work improvement is not because of the new parts, rather is a result of more careful meshing of the gears. The drag you speak of is drag between the main housing and the combined clutch/crown wheel which is made deliberately close. The clutch thumb screw merely prevents the crown wheel rotating when engaged. While it makes balancing a challenge the de-clutched drag has no impact on the tracking since the crown wheel is essentially locked to the main housing and the worm/motor which is on the output rotate around the crown wheel. Like Cuiv says the accuracy of the gear teeth and backlash free engagement of the crown wheel and worm along with accurate motor speed is what determines the tracking ability of a mount.

@@realmcerono I was able to loosen my RA, but I used a heavy duty strap wrench. I'm thinking about loosening it all the way, removing the bearing and regreasing it with some good grease. I understand why it's tight, but It really shouldn't be jerky.

Best I've seen is getting correct balance, then place or switch a small bean bag on the eastside when it flips.

So if you're 1 inch east heavy and that works great, all you have to do is move the weight in by 2" after the meridian flip, then you'll be 1" east heavy again.

how about the balance of the camera and filterwheel ? when your mount is horizontal,the camera is on the same side too,wich hangs and gives stress to the focusser. when the mount is horizontal,wouldnt it be better to let the camera hang or stand up vertical ? im testing this out because i have a heavy camera and wheel. greetings john www.astrobin.com/users/kajouman/
