Having just acquired a piece of gear for wide-field photos (which is a tried-and-true way of getting any astrophotographer off their butt and outside), the New Equipment Curse (NEC) promptly kicked in with vigour and the sky stayed cloudy for several nights. It finally cleared enough for me to run out to my backyard and catch some photons – with a very rough polar alignment driven more by excitement than skill, I’m afraid. This image is centred on NGC 3372, the Eta Carina Nebula, and spans approximately 48 degrees by 20 degrees. The Coal Sack (Caldwell 99) and the Southern Cross appear to the left of the image. The Lambda Centauri Cluster (IC 2944) sits between the Eta Carina Nebula and the Coal Sack. Below and slightly to the left of centre is the Southern Pleiades Cluster (IC 2602), and to the right of that is the open cluster NGC 3114. 

Date: 09 April 2022
Constellations: Crux, Musca, Centaurus (partial), Carina (partial), Vela (partial)
R.A.: 10h 49m 49s
Dec.: -57° 46' 59.4"
Photo stuff: 20 subs@60s ea.; ISO 1600; Canon 6D with Vivitar 35mm at f/5.6, on a Skywatcher Star Adventurer 2i mount

Hi.

I'm glad you liked these images.

One similarity is that they are both images of galaxies; our Milky Way from the inside and the much more diminuitive LMC from the outside. What we see in this image, of course, is just a part of the MIlky Way, while in the previous image of the LMC we are seeing it - or what is left of it - almost in its entirety. Another smilarity is that the pink regions in both photographs are nebulae of hydrogen gas clouds, and reasonably active stellar nurseries.

Thank you for the clarification, I understand. I am not an astrophotographer, so it is difficult for me to understand the differences and similarities, but as a space-watching enthusiast I admiringly look through your photos in the gallery https://astro.nz/blogs/blog/2-garys-gallery/
I enjoy reading your descriptions of these photos, but I often don't understand what objects you are talking about, but I guess from the description. Maybe you would consider marking some small objects in the photos with arrows? Not on the main photo, but additionally upload a copy. But only if it seems appropriate to you and will not be time-consuming.
