For those who don't know: This is Brandolini's law (also known as the 'bullshit asymmetry principle'): 'The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it' We're facing a lot of that with regard to climate change.

It's incredibly disappointing to hear that a quarter of UK schools don't have a specialist physics teacher. It's essential that we can all see the basics of how the world works & it's fun to satisfy that very basic curiosity. Physics gives us all agency in a complex world.

It took a while π€ However, now I've read a report on the Nature article I *think* I've worked it out: Gaia/Earth, Spiral Throne/Milky Way, Guardians/Magellanic Cloud and pals. What a superb title! It makes my u3a titles seem very boring π

I rather like this 'close up' - the core often gets lost in an overly-bright splodge when the wider galaxy is imaged. I've heard something about the non-merger between the Milky Way and Andromeda - I must do a little research π I hope your talk goes well: who are you speaking to?

I wish you well. I didn't restart my adolescent astronomy hobby until after I retired - and even then focused for a few years on solar system objects and binary star systems. So, I decided to avoid a thematic approach to deep sky - I'm just going for interesting targets π
bobreflected (@bobreflected.bsky.social) reply parent
Wow - I tried to do a few sketches back in the 1960s using my pocket money telescope. It was a 'sad' experience in several ways, and when I took up the hobby again in retirement it never even occurred to me to try again.

Nice images. I like your '1 hr rule'. I've got into the habit of setting something going - now two things given my Dwarf robot - and disappearing indoors to sleep for a few hours. With the longer winter nights I may have to rethink π

bobreflected (@bobreflected.bsky.social)
My pet robot (Dwarf3) worked hard for 5 hrs last night for this image of Andromeda π It even gave me the option of a star-free image, although I'm not a fan of the look (but it might be useful if I tinker with the images on my PC later π€). Everything here done from the Dwarf phone app.

From a few days ago: M27, the Dumbbell planetary nebula. A pretty remnant of a star's decline. (Almost 15,000 years ago an ageing star puffed off its out layers - just as our Sun will do - leaving a cooling white dwarf behind.)

Ah, you're ahead of me on that one - I have some targets in mind, including that one, but I think that may be a few steps ahead π Unfortunately, Andromeda is visible only from my front garden and I suspect the D3 is eminently stealable. If I have to babysit it I'd be better off going out of town π

A wise course. I'm still learning - e.g. when to select the default timing (15/30/60) so I don't have to retrace my setup steps ... again π I've barely begun on the in-app processing options etc. However, having it do its complementary thing whilst I wrangle my old-school setup is becoming a joy.
bobreflected (@bobreflected.bsky.social)
I'm slowly getting the hang of my Dwarf3, and what it's good at. Last night I pointed it at the North America nebula; the result using only on-phone processing - is quite pleasing. The lesson for me was clear: play to the strengths of the kit and stop attempting like-for-like comparisons π

Definitely not high 2nd - in fact mostly 2nd hand. However, I'm hoping it was good enough to facilitate capturing an image of a recent supernova in another galaxy.

Well done; I empathise. In my case I went to bed at 4 am, having spent time with my telescope under an all-too-rare clear sky.

Impressive I had my first outing with mine last night. I chose the Bubble nebula because I had a good view of it and an idea of what it 'should' look like. I've had no time to process the subs yet but the raw live-stack looks promising.

Well done. I got to bed about the same time as it turns out - imaging the new supernova in NGC7331 using my old 80 mm refractor ... and using my new Dwarf3 for the first time. We've had weeks of short and cloudy nights and it was good to get back out there in one of my 'happy places' π.

Sensible piece. My experience as an early adopter of Turnitin (i.e. as soon as the site licence was in place) was that it provided an excellent teaching/learning tool. I've been out of the system for a decade now, so no experience with the AI variant - but it sounds very useful.
