This frames a selection of nebulas and star clusters in Puppis in a wide 15º by 10º field of view. At centre is the pair of contrasting and superb star clusters: rich NGC 2477 on the left and sparse but bright NGC 2451 on the right, centred on the orange star c Puppis. The blue star at left is Naos, Zeta Puppis; the orange star at right is Ahadi, Pi Puppis. At bottom is Sigma Puppis. The field is filled with the northernmost tendrils of the vast Gum Nebula. At upper left is the emission nebula RCW 19. This is a stack of 12 x 2 minute exposures with the RF135mm lens at f/2 on the Canon Ra at ISO 800. The lens had an 82mm URTH night broadband filter on it. Tracked but not guided on the Astro-Physics AP400 mount. Taken from Australia in March 2024 on a night devoted to shooting 135mm telephoto lens fields along the Milky Way.
