Single 5 minute exposure of the Horse Head Nebula


Recommended Posts

I think the clouds and moon are conspiring against me.  What should be a relatively easy (bright) target is eluding me so far.  I've managed a single sub this year so far, so here it is.

QHY9, luminance filter, 300s x 1, calibrated with bias, darks, dark flats, and flats, and BPM :D

 

If I ever get a clear sky without a moon I'll give it another bash.

For 5 mins that’s not half bad. The HH is tricky because of the wide dynamic range with Alnitak in the frame. I always think the HH itself is pretty dim and needs a fair bit of integration time to bring out the fine detail.

Just looked at your full moon HH too, btw, and I’d have been very happy indeed with that.

Keep at it - if the clouds ever lift again in Norniron.
