This is the pair of contrasting star clusters in Puppis: the richly populated Messier 46 on the left and the sparser but brighter Messier 47 on the right. M46 has embedded in it the small green planetary nebula, NGC 2438, just visible here at this scale. Above M47 is the large cluster NGC 2423. At bottom is the round red emission nebula Gum 6, also catalogued as RCW 7 and Sharpless 2-302. Between it and M47 is the small cluster NGC 2414. The orange star below M47 is KQ Puppis; the one below M46 is HR 2959. The orange double star at lower left is QY Puppis. This is a stack of 8 x 5 minute exposures with the Sharpstar 61mm EDOH III refractor at and the filter-modified (by ) Canon R at ISO 800. No filter was employed here. On the AP 400 mount autoguided with the MGEN3 stand-alone guider. Taken from near Coonabarabran, NSW, Australia, in March 2024.
