California nebula and the Pleiades
Two nebulae and a cluster – perhaps the cluster – in one frame, this is the NGC 1499 California emission nebula and the M45 Pleiades open cluster with the reflection nebula it is passing through. Parts of the complex nebula system are also visible, with a hint of the LBN 777 Baby Eagle Nebula being there too. This picture was a challenge due to less than ideal transparency, odd gradients on the sky and the approaching moonrise. My starheal program did a great job.
