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 %
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

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 … Read More „XML De-Regionalizer“ »
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 … Read More „Filter confusion“ »
A part of NGC 7000 in Cygnus Ha:3960 R/G/B:1200 seconds each
Just gathered some additional light frames for M81. L:2400 R:900 G:900 B:900 seconds
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, … Read More „CCDAutoPilot results“ »
Another test image. 1×1 Binning with Ha 13nm Filter, 880 seconds exposure. No darks, no flats
