This image is essentially the result of a test night. I haven't been working on a narrowband target with my William Optics APO in combination with my CCD camera yet. Since the narrowband imaging requires long exposure times to achieve a good signal to noise ratio for the singe sub frame (1200seconds to achieve a 10% read noise contribution w.r.t. to sky signal), I had to confirm that the focuser as well as the guiding setup (off-axis guider and PHD2) work well. As it turned out, the focuser is very rigid and by using the off-axis guider, differential flexure is history.

In the beginning, I had to elaborate the right guiding parameters (essentially fine tuning) within PHD2. At the moment, I feel satisfied with what I've got. The total RMS is was about 0.45". Although I wished RA and Dec RMS were closer to each other (they differ by about 40%, where RA has the larger RMS), the total effect on numeric eccentricity is minuscule as my average seeing is usually above 2".

The foremost goal was to capture Ha data. After looking for some targets, I chose LBN179 in Cygnus as it shows some nice contrast and detail. While I was wondering what I am going to make out of the data, I chose to capture some RGB data as well in order to have the option to color the stars according to their true color. After experimenting a bit with the images and asking some colleagues for some feedback, the grayscale image shall be the official image of this project.
Since I had also processed the image colorising the Ha in red and adding the true star colors, I'm placing both versions of the image here.

If the final image is an aesthetic success is a question which I'm leaving open for the audience to decide. From a technical perspective, I see it as a success as I could confirm that the equipment works as expected (knocking on wood) and so, I'm hopefully ready for upcoming and more intense imaging projects.

I always appraciate comments, so please let me know what you think.
