Now some R/G/B subs have been collected (35 min each). Color correction was done with the excellent eXcalibrator tool.
The Ha channel is blended into the individual RGB channels with 100/10/20 %

IC 5070
Summer solstice is only a few days ahead, but last night I could get some nice frames from IC 5070 (Pelican nebula) during the short dark period

XML De-Regionalizer
Using both CCD Navigator and CCD Autopilot, I faced a small problem. Due to the fact that the computers where I create the session plans and where this plan is finally executed are using different regional settings, there is an issue when importing the XML session plan.
To solve this, I wrote a small program which converts the CCDNavigator XML file between regional settings.

Filter confusion
After doing some maintenance in my backyard observatory (collimation etc.) I noticed a confusion… my Ha filter was not in the filter wheel, but in it’s case 😉
Now it’s corrected. Here is a short comparison between IDAS V4 (confused with Ha) and the „real“ H-Alpha 13nm. Same exposure duration and background adjusted to same level.

CCDAutoPilot results
Last night the first unattended multi-target session test was successfully run with CCD AutoPilot 5.
There is still coma in the edges due to mis-collimation and the angle of the CCD is not exactly 45°
Polar alignment also needs some adjustments, also the colors are not calibrated and the flats are not very good.
Nevertheless, here are the results (M5, M81, SH2-108)
