Another shot at Copernicus crater. Just magnificent viewing tonight from Manchester UK. About 90km across and a mere billion years old. Star Trek's Beverley Crusher born in Copernicus city. Look up.

Added 4 more hours to the NGC 2244… so there 60 x 300 sec with the unmodified and uncooled Canon EOS R.
Can someone explain why the blue color is almost gone? 👀

Yesterday I did a few changes on my setup and just would try the new settings - Long story short - I’m impressed what you can get out of only 10 x 300 sec with an unmodified and uncooled Canon EOS R 😯

Bright coloured nebula in a black sky with stars

Orion nebula. Always a favourite at this time of the year. Great through binoculars or almost any telescope. This from Manchester UK a couple of nights ago

Close-up of the surface of the sun showing active regions

The surface of our nearest star today from Manchester UK. Big active region 4114 pretty much pointing at the Earth. Plenty to see.

Close up of large crater on the Moon

Langrenus crater next to the Mare Fecunditatis from Manchester UK last night. 132km in diameter. Somerville crater near the top right edge named after scottish physicist Mary Somerville. Look up. #zwoasi #asiair #am5 #registax

It's a bit of an unfair comparison between my data and the image of the #HubbleSpaceTelescope (you could zoom in so much further to see a crazy amount of details)

THE COSMIC BUBBLE – Or, me vs. Hubble. When I saw the iconic image of the Bubble Nebula by the Hubble Space Telescope, it was clear that I had to explore this target. My first attempt back in 2021 didn’t get me too excited. But a lot has changed since then. The biggest improvement came from switching to a mono camera with narrowband filters. For this image, I used the classic Hubble Palette with Hydrogen, Sulfur, and Oxygen.

I was shocked when I first looked at the data—a reaction perfectly suited to this target. The Crescent Nebula's striking structure is shaped by expanding shock waves. This began when the Wolf-Rayet star (WR 136) at the center of the emission nebula, while still in its red giant phase, ejected stellar wind that is now colliding with a much more energetic wind from WR 136. These winds create shock waves that travel both inward and outward, leading to strong emissions from hydrogen and oxygen atoms. For the first time, I used narrowband filters with my mono astro camera to extract the famous H-alpha emission line from the Balmer series (deep red at 656nm) and the OIII emission (between blue and green at 500nm) - both very common in many deep sky objects. It's standard practice to map the hydrogen emission to the red channel in a traditional RGB image, and the oxygen emission to both the green and blue channels. To complete the image, I added an hour of broadband data to preserve the natural star colors, which can be lost with narrowband filters. Swipe for a starless version, a more detailed view of NGC 6888, the two mono channels, and a short video blinking through the two channels. 📸 Camera: TS-Optics ToupTek MONO Astrokamera 2600MP G2 🔭 Telescope: Sony FE 200-600 @ 600mm F/6.3 ⚙️ Mount: ZWO AM5 🎛️ Filter: Astronomik 6nm HII, Astronomik 6nm OIII, Astronomik Deep Sky RGB 🕒 Exposure: 64x5min HII, 64x5min OIII, 20x1min RGB each (11h 40min total, Bortle 4) 🖥️ Captured with: N.I.N.A; Processed with: PixInsight
