Quote:David: Speaking of leveling feet don't forget to let us know when they are ready to ship.Eric
Quote:So you all are going to start carrying the Meade Lightbridge? If so that is cool.
Quote:Also, I see in this threads original posting that you do not list any sizes and pricing for the Apertura Dobs.What will the Price be for the AD8?
Quote:I was thing of getting an 8" dob and it was between the Zhumell Z8 and Apertura AD8, but I was leaning toward the Z8 as I saw that your site had them out of stock like they were discontinued. If you are getting them back in stock I may wait longer if the AD8 will have this option as well. That is if it doesn't cost to much.
Quote:Thanks for the fast reply.I will definitely be keeping an eye out on your site. Those leveling feet also has caught my eye. The area around my house back in Illinois is not to level. Even the slabs around my pool. Ground settling and all.
Quote:David,How does the stability of the leveling feet compare to the standard feet of the dob base as far as vibration a the eyepiece? Thanks.Tim
Quote:After moving the Z12 into position the damping time for vibrations to stop was significantly longer than usual, I'd say about 3 seconds. At low power on the DSOs this was not a problem. But on a mixed bag of objects evening (also viewing the Moon at high power) it was a bit distracting.
Quote:I gave Dave's suggestion of tightening the bolts on the base legs a try. (Doh!) I only tightened them "thumb tight" not "wrench tight" and I noticed the vibration time was almost halved. Since I plan on using the HALO at several sites tightening further is maybe not a good idea. I found the vibration damping time to now be just fine.
Quote:As far as stability I keep the leveling feet as short as possible, and making adjustments with just two levelers to bring the base to up to level.
