I'm not familiar with the mount, is 6V correct ? Also measure all the contacts on the board where the white socket is soldered for volts when you press left/right, and compare with the other motor. There doesn't appear to be any grease on the worm and worm wheel, so perhaps it's jammed. Use an allen key in the worm coupling to gently rock the worm. Michael

By "M42 lenses" do you mean: 1. Pentax etc M42 Lenses with M42 x 1mm thread and 45.46mm Flange Distance ? Which require a M42 to Canon EF-S Adapter. 2. M42 x 0.75mm thread lenses made to the Universal T-Mount Lens spec, with a 55mm Flange Distance ? These can be fitted to almost all cameras with almost any Flange Distance with the right adapter, which is why they are "Universal". If so the adapter spec needs to read "Converts M42 x 0.75 (T-Mount) thread to Canon EOS Mount". Confusingly the more common "Canon EOS T2 Adapter" is also M42 x 0.75mm, but is for adapting the Canon camera's bayonet fitting to a M42 x 0.75mm thread for attaching to telescopes etc, not lenses.

It would be easier to enlarge the chamfer on the lever's head with a file. Michael

As Olly said, adjusting the black point and mid point sliders. will give you an image good enough to adjust colli:

As Craig said. Can you install the mirror with the clips over the chips ? Michael

We need some clues, such as what compass direction the camera was pointing at, the time of day, approximate location, and what focal length lens. Michael

That's the problem, which is correct ? Michael

I agree with those explanation, if it had said "fourth closest star system" Does a "star system" mean a multiple star system, or a "star and its planets" as in our solar (star ?) system ? Trying not to be pedantic, I was initially just pointing out wiki errors. Michael

Sorry, how does "fourth closest star" and "the closest single star to our Sun" compute ? Michael

Seems to be conflicting info online regarding Barnard's Star - no surprise 😞 From the ESO link: the closest single star to our Sun Barnard’s star is the second-closest stellar system I thought it was a single wandering star ? From wiki: "it is the fourth-nearest-known individual star to the Sun " "and is the closest star in the northern celestial hemisphere". But it's good that a least one planet has been detected.

From the Instruction Manual, for Alt/Az. Page 37/38. 3. Set Home Position d. Move the base of the telescope so that the computer control panel (13, Fig 1) approximately faces south. For Equatorial Wedge Mounting, the control panel points north. And when the marks on the RA ring are set correctly, the OTA Home Position from where the Meade PA and Alignment routines are started is "upside down" with the finder under the OTA: Michael

Apologies OP, oddsocks is correct. I'm not sure how you tell the difference, but post 4 in this link is how to upgrade a 495 to 497: https://www.cloudynights.com/topic/668690-meade-autostar-495497-firmware-applications/ Michael

If you do an internet image search you'll se that the 495 is missing the number buttons. Michael

Hi Laurence. 1. Cal was marred , Orthogonalty error. 2. Guide rates too low, need to be at least 7.5arcsec/pixel 3. X and Y axis scales too large to see any detail. But that's only what can be seen in your screen grab. Michael

Your first post indicated a connection problem, and we merely pointed out that accordidng to your description of the setup, it was probably wrong. Michael
