Focal point for T7C camera with 1.25 inch extension tube on my CCDSPEC spectrometer
Shows where to put T7C camera to obtain focus on split. Requires extension tube.
Having to take a picture, as I need to pinch the 1.w5 inch extension tube to try and obtain focus on my guide camera tonight!

Resolving the problem of my Dobsonian telescope falling off the equatorial platform when the platform is at an angle
My solution to the problem of my telescope falling off my Equatorial Platform. I have replaced the central bolt of the Orion UK Dobsonian telescope with longer one and bolted the base of the rocker box to the top of the platform. I have replaced the nut with a wing nut so that I can easily attach and detach the rocker box from its base.

Cone Nebula (SH2-273)
Hi All,
Still not able to get PHD to work. So here is an unguided image of the Cone Nebula. This is 50 x 2 minute subs in Ha. The Scope is the Takahashi Epsilon ED180 @ f2.8 and the Atik 4021. This gives a Field Of View (FOV) of 102’x102′.
I’m getting the data for RGB so will post a HaRGB image later.
For those who don’t know, if you hover the mouse over the image and click, you get a magnified image.
