    Default Can my 6SE Mount handle this weight? Lots of questions.



    I have mounted the Orion ST80-A on top of my Celestron 6SE. (See attached picture). The question is can the mount handle this weight?

    Another question is do I move the ST80 towards the back (back heavy) or forward. Also, how do I adjust the scopes so that I can use the two scopes at the same time?

    Can I mount my camera on top of the ST80 at the same time?

    Oh that's a lot of added weight for a small mount I would think the clutch will slip sometimes unfortunately . Try it out

    Thanks for the reply. My main concern will it damage the mount?

    Perhaps over a prolonged period ?? Although you may find it slips so much that it's unusable . I have a friend who did a similar thing with a 80mm refractor and Baader Clicklock diagonal and it just wouldn't stay firm so he gave up in the end . Try it and if it's firm and doesn't slip then It will be fine.

    Alt Azimuth mounts tend not to be as sensitive to weight as a GEM. For the past 6 years, I've ran my SkyWatcher SynScan AZ GOTO mount as much as 12 pounds when I am using it for astrophotography (C6S OTA, DSLR, finder, etc.) and 10 pounds for visual work (C6S OTA). It seems none the worse for the use. The only downside is stability is reduced. My 4 SE mount can also handle this configuration as long as the load is balanced. The 6/8 SE mount ought to be better. If I use the 4 SE wedge and put the mount in the equatorial mode, my payload is cut to about 6-7 pounds

    However, I think that your biggest problem will be mount stability. With the exception of the tripod head, the tripod used for the 6/8 SE is the same as the tripod used for the 4/5 SE. The extra weight will have an impact upon mount vibration and overall stability.

    I should add that if it slips it's the clutch that is slipping so no harm is done to the gears and the mount is fine :-)

    Thanks. If the weather will play ball I will try it. But after a week no go.

    Total Balance of the 6Se plus the mounted ST80 should be very slightly heavy to one end ..makes no difference if it is either slightky heavy front end or back end...BUT most of us go with the back end being slightly heavy with the Se mounts... This was the way these scopes left the factory BEFORE they added the dovetail to remove the OTA from the mount (that is the OTA was fixed to the mount itself) ...

    The Clutch adjustments are easy to make BTW...correct torque is between 16 and 19 INCH pounds from the factory and if everything is balanced correctly you should be ok..over time it most likely will slip so just tighten the darn altitude adjustment nut maybe a half a hair ....

    This is my original 8i set up the way I have run it for the last 10 years ,,,I do adjust the clutch about once a year ..only takes 5 minutes...
