20 minutes Rosette

Recommended Posts

Yet another test in the (long) path towards fettling my Hyperstar, and my first ever image of the Rosette. 

I didn't take very long over capturing this, because it was windy and getting rather cold!

  • Hyperstar 9.25" with Baader UFC and IDAS P2 filter
  • Avalon M-Uno guided and dithered with Nebulosity
  • 10 x 120 seconds (for a total of 20 minutes)
  • Lightly processed in PI

I haven't yet got around to supporting the camera cables correctly, so the bright stars show that.  The spacing is still wrong, so the corners are terrible.

Suggestions for improvement very welcome.

Thanks for all the encouragement.  I'm having a tough time with flats for the Hyperstar, so that's certainly one area I'll try and improve when I come back and visit this for longer.

I've recently revisited this old data, and nine months on from the original processing, I've had another go (PixInsight, DBE, some masks, and more careful stretching.)

To recap the basics:

  • Hyperstar 9.25" with Baader UFC and IDAS P2 filter
  • Avalon M-Uno guided and dithered with Nebulosity
  • 10 x 120 seconds QHY-8L OSC (for a total of 20 minutes)

Here's the result, which actually makes me feel that the Hyperstar is better than I thought it was (and my processing was worse...)

I'm encouraged to give the Hyperstar a further outing to see what this year brings.  As ever, comments welcomed.
