    Default What in the world??



    I went out last night for the first time in a while and ran into two new issues. 1. My guiding was awful. I never have an issue and tonight was just garbage, not even closed to round stars. They were smudged in a zig zag pattern almost. The only new variable here is I was shooting the Cygnus wall which is nearly straight up in the sky. I read somewhere that PHD can struggle there.

    2. And even more baffling. Most of my images ended up looking like this...

    Baffled.

    That was my first impression too - ultrasound. Was there a stray light source around somewhere? A possible light leak in the optical train?

    It looks like it is going to be a stray light source. Which is really disappointing because this is the first time I shot from my patio, it was quite nice sitting inside in the AC instead of sitting outside with mosquitoes in the Florida heat. I’m going to try again tonight and if it happens again then I’m gonna have to assume it’s a light source of some sort. And I could’ve sworn my polar alignment was good but I’ll doublecheck again tonight and maybe that’s what caused my problem

    I just showed your image to Scully and Mulder. They suggest sweeping the area with a Geiger Counter - buuuut, on a more serious note, the aberration seems worse on the upper left than the lower right. Are they all like this, or do they vary? The tracking issues and the "cone" of light seem to be separate issues. Was there anything that could have caught the moon and reflected into your OTA?

    The moon was behind the building I was shooting from and I was shooting narrowband, someone mentioned something about aberrations. I’m just stumped. I haven’t been my normal intelligent self lately. Life.

    It is a snap shot of a laptop screen. The 'ultrasound' is a reflection on the laptops screen. At least that is what it looks like.
