Thank you Avani. We are awestruck.
Is there no limit to your magic?

This is what the Skywatcher Nirvana / WO UWAN 16 mm looked like when they still had a twist-up eye cup.
I have this eyepiece. It's compact, comfortable and optically very good.
There aren't many focal lengths, just 4, 7 and 16mm. The 16mm has the largest eye lens and plenty eye relief.
Two months back, Agnes posted a report on the new 16mm Nirvana:

Excellent!

Very fine images indeed!

Yes, you probably have some processing artefacts here.
How did you do the processing? Could you give it another try?

Splendid job!

Congratulations!
I think you have a very good mirror there. The strehl ratio is 0.993. Wow!

The transient star is more yellow than its permanent neighbour.
We should call NASA.

I actually like the light here. It's silvery on the rocky outcroppings and the wrinkles on the maria are well defined.
But I believe you of course: now you must make us a better image! 🤪

Gee, that's a good one. I'm going to like this contest. I love the Moon.

10x50 has a wider true field of view, 20x80 shows more detail. 10x50 has more applications: trekking, sports, close up views, horizon and sky. 20x80 is more for horizon and sky.
I'll tell you what I have and why:
I went for an 8x42 binos for its light weight and its large true field of view (8.1°). Closest focus is 2m, so it doubles as a butterfly bino. It is small and can always come with me and it finds any target in a second or so. I prefer a monopod for it for convenience.
What I miss out on in the sky with the 8x42 I can see in my 73mm APO. Over 700 euros, but much better than any binoculars I ever tried. It needs no more than a photo tripod and a few eyepieces. It is also used as a spotting scope. With an extension tube, nearest focus is 3m at which the scope becomes a long distance microscope. I have a choice of magnifications for it from 12.8x and up.
For extremely wide views I have a pair of inexpensive 4x21 binoculars with a 17° true field. The central 10 degrees are quite well corrected. Since I have the 8x42 I use my 7x50 less. With 14% more magnification the 8x42 has the edge on it.

Oh yes, it's good!

County Gate; Webbers Post; Holdstone Hill; Wimbleball Lake – these are just some of the fantastic spots you could pitch up for a night under the stars. If you don’t have your own telescopic equipment you can hire all you’ll need from one of the National Park Centres. For a great stay, we recommend The Old Rectory Hotel close to the coast – it was recently voted ‘Best Small Hotel’ by Visit England.

The blue snowball looks blue to me. That's about it.
The colours of deep space objects are real, but very subtle.

Hi
This video was published on YouTube in March of this year and describes the development of universe in exponentially growing steps through time. That probably means that it is highly speculative, but it is interesting.
I'm about halfway through at 7 billion trillion trillion trillion years in the future, and quite curious about how it will end.

Wow.
It may not be scientific, but this is great fun and beautiful to watch!
Thank you, Avani.
