The Leo Triplet -

It's taken me a while to get a result I'm somewhat happy with for this beautiful galaxy cluster in Leo. Comprising NGC3628 (The Hamburger), M66 & M65 - they'r only a mere 35Mly away - there's plenty of detail to be seen and some interesting contrasts in colour and structure that makes this grouping quite an intriguing target.

This image comprising of 25hrs (5hrs in 2023 and the rest in Feb/Mar/Apr this year from by B7 backyard - a tricky target that doesn't even reach 45degrees above the horizon from my location and sits in the Sydney CBD light dome.

Using the c14 Hyperstar (Antila Triband RGB broadband) has allowed me to reveal some faint detail, and a section of the tidal tail of NGC3628 can be seen, but the light pollution gradients were absolutely epic and I had to compromise between tidal-tail detail and a nice background so the extents of this tail unfortunately are not visible.

I reckon I'll put this one to bed there until I have my very own dark sky observatory lol

Some cropped images are attached to the post but recommend checking out the better resolution and zoomable image here.
