In general, it applies not only to telescope, but to to any astronomy tools as well. A friend of mine ordered an ASI294MC Pro, an ASIAir, and a mini ASI120MM. I told him I'm holding him responsible for the dreary nights that come ahead from now 'til spring.

Clear as a bell mel.

 

Seems to be pretty sharp on the moon but needs 2ndary  collimation.

I just got the scope. All in all in good shape. Will see what it does tonite.  Deep sky looks good as well. Mount is not gonna cut it at all. Plan to rig up the Cave 1.5" mount to hold this OTA this weekend.

Should be solid on the Cave mount.

 

For years I used a home-made 8" f/7 Newt on a Cave 1-1/2" mount.  Solid as a rock.  Still have both, though the Newt has been taken apart.  I want to change it to a low-profile modern focuser so I need to patch the hole and re-drill a new one forward a few inches.  Parks tube.

The DEC lock just don't work..  Not sure if Meade used teflon as the the bolt is teflon and the DEC  SO- MO does not seem to work that great and it also has a teflon bolt to lock down.  There is so much backlash in the RV axis.  I am sure the whole mount needs a tear down and cleaning.  The 8" OTA is very light and does not weigh much more than the RV6 OTA.

They were nylon. I’ve found that they tend to harden over time and don’t hold as well. Or break easily.

RA axis is very stiff on the Meade mount.  Sure can't even pull it out or even know if has bearings or is press fitted.  Anyone ever take a 826 Meade mount apart?

I just used a normal metal bolt and it works fine now.  It was just so stiff to even turn let alone not lock down.

Well i got to put the test to the optics and Cave mount. I find this OTA the max for the Cave 1.5" mount, got the drive all set and it holds it fine with some jitters while i focus.

 

I would say the mirror is very good, but i think it could be made better with a refigure.  Seems to do very good with a 3mm Delite, but seems to lack that extra pop i have had with my Zambuto's or the RV6.  So i gotta wonder who i should send it to?  I wonder if Mike Lockwood would take it on?

Well just swapped out the neck breaking 6x30 finder for a neck saving 8X50 RA.  Even fit the stock finder holes for a easy plug and play..
