Within its limitations, the #DwarfII is really quite remarkable. Take this image of the Lagoon Nebula (M8), for example. Shot on a near-full moon, in the middle of suburbia. This is *only* 150x15s frames, gain 60. I have used a dual-band Ha/OIII filter. These were stacked in #siril with a little final tweaking in #Snapseed.
Is it a great shot? No. Is it a good shot? Yes. And with very little effort.

After previously photographing IC 63, the Ghost Nebula, with the 5 inch refractor at f/7.5 (952mm), and seeing how small it is I wondered how it would look using the C11 at f/10 (2800mm). Squeezing out nebulosity with such a slow setup is not easy.

#Mercury "librates", meaning that its #rotation rate is not constant. This unsteady rotation induces a flow at the top of its molten core. There's a chance the Bepi-Colombo mission can detect the magnetic signature of that flow, which will give us information about the core.

Here's my latest, it's a 3 panel mosaic this time. It was too big for mastodon (10k pixels wide) so I had to downsample it a bit.

THERE IS A FRESH CORE COLLAPSE SUPERNOVA IN NGC 1097

I've imaged this galaxy many times before so a fresh supernova would have been a good pre/post image to catch!

One thing I really love about this galaxy is the central star-forming ring, which measures about 5,000 light years in diameter. It's a beautiful feature and one that can be captured from backyard telescopes.

A couple of older images from me first. NGC 1097 and a close-up of it core, where I compared my very shabby 1-hour, no darks, flats, bias image to Hubble's of the star formation ring. Amazed I could even get any of these results from my light-polluted backyard.

Supernova 2023rve was discovered on 8 Sept 2023, and is a great target for southern observers right now (crying) ... the galaxy reaches almost the zenith (85-degrees elevation) around 2:30 am Sydney time ... the perfect imaging time!

Also sharing a capture from South Australia by Kym Thalassoudis.

Southern observers, turn your telescopes to NGC 1097! A pulsar was just born (well, 48 million years ago it was) ...

All of the below images have been processed by me, at home - so anyone can do the same.

I think this is such a nice way to get public engagement - teachers could get students to do this! It puts the science back into the general public's hands to play with.

Just a quick thought.

If JWST happens to find traces of possible life on other exoplanets, since the light Webb has captured is just reaching it, then possibly the planet’s possible lifeforms are extinct? I mean, it is 120 lightyears away.

Edited for clarity. I just noticed I said the planet AND life. I did not mean to say that. 😂
