| Comment : |
After 3 months of hopeless cloudy sky I got the opportunity to setup my telescope.
The rebuild of the mount is not fully tested yet and a lot of tweaking has to be done.
When auto guiding I now have a total rms error in the range 0.6" to 0.9". |

Here is a zoom in on the M102.
A little bit better resolution than earlier. |

This was long time ago I tried to take a photo of.
Increased focal length give some more detail.
Look closely and you can see the dark band that divide the galaxy in two halves. |

This galaxy is far away and in my telescope it's just a tiny dot in the center. There are two galaxies at least in the photo. |
