Set up the 18" on Mt Stromlo earlier this week.....

Aligned on Rigel Kent and Altair using a Nagler 22T4 and just centred the defocused star image, alignment successful at 0.00 I doubt I will ever beat that

After that even the smallest objects at 319x were right in the centre of view...

Sounds like a certain Vixen GPD2 you used to own Matt Out of ALL the myriad of astro stuff I have had, it's the one constant - I tend to work my scope choices around the mount! (I sold the mount twice - bought it back each time, as nothing came close to how precise that particular GPD2 is)

Extreme Resolution Encoders - Oh yeah, baby!

I've just put through its paces these new extreme res encoders on my scopes. My big dob has 311,296 step encoder on the az axis and 650,500 step encoder on the alt. I then went nuts finding object after object from one side of the sky to the other and landing each comfortably inside an 8' true field of view eyepiece.

Oh, and I didn't need to change the way/speed at which I moved my scope.

Awesome Serge! Truly AWESOME!

Alex.

That sounds great Alex, I'm pleased it's working so well for you.

I get my new SDM soon and it will have these new encoders fitted. Coupled with the Mpoint calibration and ServoCAT Autolock, the Nexus DSC provides professional grade performance. Especially as my dob will be permanently housed in a ROR obs. I also hear there's possibly a home function on its way for the Nexus DSC, so I will only have to do my 2 star alignment once, and never need do it again.

Allan,

Do you have any updates on Serge's EQ6 / nexus project? I emailed him some days ago and he has yet to reply to me. From what he told me at SPSP this will be a straight plug and play for the EQ6 using the existing hardware on the drive.
Did I understand him correctly?

John

Hi John. Serge has had my Atlas AZ/EQ-G for 11 weeks now, so I think it is a bigger job than he anticipated. That is to get the Nexus DSC to run the mount in Alt/Az mode only.

I'm not aware of what will be required to get the EQ6 to run via Nexus. I know it's not currently a plug and play as you mention. I haven't asked him about that because running my mount in EQ is not something I'm interested in. I suspect he will need an EQ6 mount on hand to get it configured and then release a new firmware update, which is the process we are going through at the moment with my mount.

I'm sure Serge will get to your email, or post here if he sees your question. I do know he is very busy, the price you pay for being so popular.

Nexus Dsc

👍👍👍
For nexus Dsc, only had it since Christmas and love it, makes life easy to find any object you want.
I use a fixed pier and to have a home function would be great, no more star alignments again! :

Thanks Allan,

In fact Serge contacted me a short time after your post! He is still working on it and hoping to complete by the end of the month. I will leave him to do his good work. I am keen to get the Nexus. The SynScan has room for only 25 user objects and I have filled it with obscure double stars. Been outside the past hour and a half checking them out (seeing not good). Am keen to get a controller/database with a bit more capability.

I've had my Nexus DSC since February.

My 12" Lightbridge was used as "patient zero" to produce a kit for these scopes. (All sizes)

I couldn't be happier with Serge's excellent service & advice.

The Nexus is simply brilliant, and talk about encoder resolution!!

AZ: 311,296.

Alt: 952,000.

Simply, the best!

I bought my Nexus DSC from Serge in Feb 17.
My 12" Lightbridge was the "development model" for the "Lightbridge kit"

The encoders are just the start, AZ 311296 steps, Alt 952000 steps.
Serge had to design and then produce all the hardware to fit my scope.

With my personal setup of control box (dew heaters & fan), I couldn't have the post with the dsc on the side of the mount (toward the rear)
I had to mount it on the side (front end)

Whilst this worked out, ok. I did tend to lean into it, especially with a lot of clothes on for winter.
I have now moved it to the upper tube assembly (with mount and cable relocations), this is infinitely better to read and use.
