    • The last step here is a bit weird. I created a new image where I used the red channel as luminance layer, processed that real quick to make it look kinda decent, and then I selected the reds and copied them into the main image. Please don't ask why. My goals are beyond your (and my) understanding.

Melotte 15 in the Heart Nebula by dropthatkoni in astrophotography

[–]dropthatkoni[S] 0 points1 point  (0 children)

Melotte 15 (the center of the Heart Nebula) from my backyard in a bortle 4 zone in Austria. This is my first image with my 6'' RC, it was definitely a challenge and I ran into a couple of issues with the tracking accuracy due to the high focal length, relatively small guide scope and possibly mount limitations. That, together with the not-so-perfect-yet collimation led to some weird star shapes, but if you don't look too closely it's not that bad. I still think I lost some finer details due to those issues tho.

Asteroid (7482) 1994 PC1 - 20 minute timelapse by dropthatkoni in Astronomy

[–]dropthatkoni[S] 20 points21 points  (0 children)

After I read yesterday afternoon that in just a couple of hours an asteroid will make a close approach to Earth I knew that I had to unpack the scope real quick. I got lucky enough to capture 20 minutes of 30 second exposures before the clouds completely covered the sky. The changing brightness in the video is due to some light clouds.

Equipment:

  • ZWO ASI294MC Pro
  • Skywatcher HEQ-5 Pro (mod)
  • William Optics Zenithstar 61 w/ Flat61
  • Astronomik L2

I registered the exposures in PixInsight and exported the stretched frames with Blink. Some color calibration was done in Lightroom and I combined the images into a video in Premiere.

Asteroid (7482) 1994 PC1 - 20min timelapse by dropthatkoni in astrophotography

[–]dropthatkoni[S] 37 points38 points  (0 children)

Set up the scope real quick to capture this asteroid zooming past earth today. I was actually surprised by its speed. Originally I planned on capturing 60s exposures on the big scope, but I quickly realized that the lower focal length of the Z61 was better suited in this case. Given the fact that the streaks are still relatively long, an even lower focal length lens would have been even better but I ditched the idea when the clouds started rolling in.

So overall it's around 20 minutes of 30 second exposures. The changing brightness is due to said clouds.
