Another benefit to this approach is that the field flattener can be used for visual. Definitely helps wide field observing.

Would it be possible to design an FF that's installed before the focuser tube (mechanically like a Petzval)? This would take out all the headaches for checking filter thickness, back focus, buying PP adapters... Glass would need to be larger so more expensive to build, of course.

It's just an Ethernet cable with one end pinned differently. I made a custom cable when I bought my first box upon release.
 
While it does work with the motors, that voltage difference is real. Also for Optec motors that home themselves (i.e Leo) the homing function will stop working if you use the pegasus controller. So I don't advise using it with those products.
Interesting.  Thats good to know about the LEO.

As far as I know the UPBv2 has not worked with the FT/Optec motors.  I tested it with my LEO and my FT40 motors and it didnt work.  I was told by Wayne at starlight that it could even damage the motors. 

More recenty Jeff at Optec told me that Pegasus has since released an adapter cable so you COULD use the Pegasus controller.  I reached out to Pegasus and they confirmed that their adapter cable is not just an RJ45 connector, but that they remapped the pins.  You can see the diagram on the Agena Site: https://agenaastro.com/pegasus-astro-stepper-motor-cable-for-starlight-hsm-handy-stepper-motor-peg-cmot-hsm.html

Dan,

I've been using the Optec FT focuser motors with my AP scopes and love them.  I have the FT20 for the stowaway and the FT40 for the 130GTX.  It looks like the new 110 will have the same size focuser as the 130GTX, so that would be the FT40. 

Pegasus Ultimate has a built in controller that can now be used with the Optec and Feathertouch motors.  You just need an adapter cable to map the pinouts.   Of course, the motors also have their own (optional) controllers as well.

Thank you, Alan. Although this camera has a dedicated power input and its own software, I run PCs so it looks like the camera is headed to the garbage can. Oh well!

Funny the topic of lubricating gears goes all the way back to the development of pendulum clockworks. In the beginning the master clock makers knew how to match differing woods that contained natural oils and were self lubricating. This could not have been possible until after voyages to the new world - Africa and South America in particular - produced lubricious woods compatible with hard dry woods available to the new world clock makers. Metal clocks had been around since even the Egyptians and Greeks. But the pendulum clock demanded a higher level of lubricity on the pendulum mechanism even though a simpler device. -Best, Robert

Re: Two Solstice Transits

Hi Brian,

Mac computers still support firewire but it takes a couple of adapters to connect through the thunderbolt (USB C) port. PCs didn’t support power through the firewire bus which made it particularly difficult to run firewire cameras, I think. Biggest challenge is to find software to operate and process the streaming data… and Apple abandoned support for its Quicktime video protocol. So I am using a couple of Macs with older operating systems and running a wonderful Mac program called AstroIIDC which unfortunately is no longer available. 

My Macs, cameras, software, hardware and telescopes are all vintage at this point. Fortunately I am still a spring chicken. I will have to find a youngster someday soon who can teach me how to use a PC.

Cheers!

Hi Alan,

What do you use to talk to the Firewire camera? I have an older cooled camera that uses that interface but I've never been able to use it because no computer supports it anymore.  Awesome pics, by the way!

Thanks in advance!

Re: Greasing/maintaining mounts

I would check the manual for your specific mount. The first one I provided was from the 1100gto manual.
This below is from the Mach2 manual but not sure which mount you have

Using the entire worm wheel ensures even wear and extended life. Under normal use the mount moves back and forth using only one half of the worm wheel...the other half is not used. Here’s what to do: Send the mount to Park 1, unlock the clutches and push the mount to Park 4. Lock the clutches and you’re done. Do it twice a year...that should be enough.
