LBN 438 in Lacerta

Recommended Posts

    Hi,

when I was young I was fascinated by the famous image  by David Malin of CG4 in Puppis, nicknamed God's Hand, a star-forming region in the shape of a hand which seems to be about to grab a distant galaxy.

I realized recently that there is a strikingly similar nebula in the northern hemisphere, LBN 438 in Lacerta, accompanied by the distant galaxy PGC 69439. I spent two nights on this object, which is quite challenging for my Bortle 7 skies 20km from downtown Paris. Overall there is 11 hours of luminance in good seeing conditions (median fwhm 1.75" and limiting magnitude 21.5 on the luminance stack), and only 60 minutes of color data.

Thanks for looking and clear skies,

 

Dan
