ScopeDome 4M to be installed


I bit the bullet and finally ordered a Dome.  So my Roll off roof will be going away and unfortunately my warm room as well.  
The Warm Room is too close the main observatory floor and with the dome in-place.  the Dome will not clear the warm room wall as it’s built.   I would need to move the warm room or make the make floor larger and redo the Pier and I am electing not to do that.

Below are images of my Dome finishing testing at the factory.


Currently the Dome is on the Boat from Poland to Port in New Jersy.

After it arrives there it will be transferred to a flatbed then shipped to my property.

One the Dome hits the US I will start to tear down my existing observatory to the point it will be ready for the Dome

More updates to come on this project.




Trying out

Decided to try out and this the initial result.

I did have troubles that’s weren’t clear from the messages.  like Not having access after paying for a plan.  come to find out if you don’t complete your member details (address for example) you can not image.

Also,  I did this in LRGB (not really a good choice for LRGB though as a test) but during the Blue pass the auto-guider had trouble and ruined the image.   Fortunately, the refund system is quite easy and got that refunded and will retry the exposure.

Below is the L image which is a stack of 2 600sec exposures

Below the image is the equipment information

I have to say,  I don’t find this as satisfying as using my own equipment

Another 3D Printed Part

This time I designed up a holder for my Microtouch Focus Controller.   This was the First Draft of the holder.   The second draft has better corner support and slots to allow a strap to be used to secure the controller in place.   While I designed it for a snug fit I image as it heats and cools it could come loose.   I’ll attach a rendering of the new version shortly.    my 3D printer is having it’s extrusion head cleaned up and tuned up so I’m not printing at the moment.    BTW:  it took 14 hours to print this one.


For the curious,  the white PCV tube is my home made Daytime alignment tube.  Pin hole plate in front and a white Plexiglas in back to project the sun.   Made it really quick since I had to re-align the mount coarsely after removing it from the pier



3D Printed Cover for Paramount

As I mentioned in my previous post I am re-working my thru mount cabling.

I am running a SBIG power cable thru for the STL11000M, a USB and USB Power for a Hub to be mounted on the versa-plate and possibly a power cable for an older SX7C camera.

I have designed the plate in Autodesk Inventor and printing my test one to check how it fits and it’s pretty darn close.

Here is the test fitting


A quick view from the side.


For extra “Anti-Mouse” enforcement.  I added some steel wool as packing.   Though I”m not sure of what if any electrical interference it might cause (or prevent).


The larger disc is a copy of the actual back on the mount (for testing in the house) and is not part of the real part but I left it because my screws are to long and needed the extra length to attach it properly.   I will probably post to thingverse when it’s finished. for anyone to print.    I plan on painting it black to match the Paramount when finished.

Long time no update

So I wanted to do something so first of all


My weather computer died so i’ve not had an weather updates since October I do plan to fix that.

After that I had back surgery in October so I’ve not been out at all until recently and that was to show my observatory to a friend and made a massive error.  I did not close the roof all the way and it rained.   no damage to equipment but floor was soaked as well as the rear wall.   Thankfully it wasn’t worse.

After things are dry (and should be by now) i want to finish the interior and paint it and get back outside (weather permitting)


Also a note, I do use anti-spam software and if your comments get caught as spam by It I do not review them.  I delete them.  the amount of posts is surprising but virtually all are spam so no sense in taking a closer look.

Welcome to The Kilbourne Observatory

About The Observatory

Kilbourne Observatory is located in Sunbury Ohio which is 33 Miles North of Downtown Columbus.
I have a backyards observatory Rolloff building (11′ 6″ x 11′ 6″) with a recently added warm room
that is 8′ x 11′ 6″.  The Observatory has a single 120V 20amp line run for the Heating/Air and the Roof Motor
the remaining power is 2 210w 18V solar panels feeding a 12V 90amp deep cycle batter and a 2500watt inverter.

In the Observatory itself is a Pier Tech II pier with a Bisque Paramount ME mount
OTA’s include Astro Tech At90EDT, AT130, AT10RC(Optec TCF-S Focuser) and AT12RC (Starlight Focuser) along with a Meade LX200R 12″ OTA, Meade 8″ SCT (JMI Focuser)
and a Meade ETX90 OTA.

for Imaging I use a SBIG STL-11000M2 with MaximDL and CCDSoft

Control is through TheSkyX with T-Point

Network is run to building as well which lets me use RDP to control things from the house if needed

I will be posting more infor and pictures of the observatory soon as I figure out where I put them
