I've been absolutely fascinated with the effects I can create with a fibre optic brush mixed with various lights. For example in this one I dusted off a LED Lenser P7QC, a trusty old flashlight I've had for years which has been sat in a drawer for nearly as long.
No Photoshop, no AI, only a 90mm macro lens in the dark.

Comet C/2017 T2 (PanSTARRS) is in the astronomy news this month and toward the end of last week (May 22, 2020) it paid an approved socially distanced visit to two bright galaxies - our old friends Messier 81 and 82. The rendezvous makes an image of beautiful contrast in color, shape, and form, all set in a field of colorful stars and even more distant galaxies, laced with an Integrated Flux Nebula background.
Notes on the galaxies: M81 (at the top) is 12 million light years from Earth and was first discovered by Johann Elert Bode in December 1774. It can be found in a small telescope about 10 degrees northwest of the constellation Ursa Major (the big dipper). The spiral arms of M81 are well defined and prominent. They contain easily resolved blue-green and red regions of new star formation. This beautifully symmetric galaxy is an example of what astronomers call a grand design spiral galaxy.
The galaxy below M81 near the center of the image is M82, sometimes called the cigar galaxy. It is a starburst galaxy and Hubble images reveal massive clusters of stars near the core of the galaxy (the red regions in the image). The average mass of one these clusters is 200,000 times the mass of our Sun and in this high density, energetic region new stars are being born at a rate 10 times that of our entire Milky Way galaxy. The cloudy background in the bottom portion of the image and elsewhere is Integrated Flux Nebula, reflection from dusty regions in the galaxy illuminated by the integrated light from the stars in the galaxy - very, very faint.
Comet C/2017 T2 (PanSTARRS) is just passing through and is now close to Earth. It was discovered by the Pan STARRS survey telescope on Haleakala on the island of Maui in Hawaii in 2017 when it was still beyond Saturn. It is in a hyperbolic orbit that is inclined 57 degrees to the plane of the solar system. It probably formed in the outer most part of the solar system - a dynamically new comet. This means it is not a periodic comet and will never return close to Earth. By the year 2025 it will be 15 times the distance from the Earth to the Sun (an astronomical unit or au) from us and magnitude 21. It is presently magnitude 11.7 and 1.7 au from Earth.
Constructing this image was a massive job and I worked on it pretty steadily over 3 days. Three factors contributed to the processing tasks, the comet is moving, we used a monochrome camera with 3 color filters (one shot color is always easier with comets), we used dithering between sub-exposures to generate the files for what is known as drizzle integration (this improves image quality when the pixels are under sampled - larger than the resolution of the telescope optics or the seeing). I collected 94 sub-exposures of 5 minutes each, making 4 hours and 42 minutes of total integration time on the night of May 21-22, 2020. PixInsight was the principle tool used for processing and resulted in a 64 megapixel drizzle integrated image. The telescope was the 8” RH 200 astrograph at FOAH Observatory, Magdalena, New Mexico, owned and operated by John W. Briggs. I controlled the telescope and camera from my house in Albuquerque remotely over the internet and John was onsite collaborating and minding the dome.

This images was captured the evening of 2020-09-15 with a William Optics RedCat 250/51mm Petzval refractor and ZWO ASI533MC cooled astrophotography camera controlled by a ZWO ASIAir Pro. The ASIAir is a marvel aiding and automating much of the shoot. Polar alignment and focusing with my single axis Vixen Polarie mount are a breeze. I monitored imaging session progress inside our cabin with a wireless connection to my iPad. This image includes data from 70 minutes of light frames and 15 minutes of dark frames taken at unity gain (101) at -10C in 30 second exposures.
Most processing was in PixInsight with final crop and exposure in PhotoShop and noise reduction in Topaz DeNoise. This colorful rendition captures the structures of the nebulae around the Pleiades and the colors of the nearby stars.
P.S. Reprocessed with the RC-Astro Noise/Blur/StarXterminator plugins to PixInsight.

Using the corner of my roof, I was able to capture the full colors of this corona without the harsh brilliance of the sun.
A corona is defined as one or more sequences of small-diameter coloured rings centred on the Sun or Moon.
Coronae are caused by the diffraction of light passing through small particles of uniform size. Usually these are water drops or ice particles, as in mist, fog or thin cloud (in this case cirrocumulus).

Here is a small clip from a larger view of IC 1396 in the constellation Cepheus called the Elephant Trunk Nebula. The Elephant Trunk Nebula is about 2,400 light years from Earth and stretches for over 20 light years. This area is also a star forming region containing over 250 young stars both in it, and around it.

Deep Space Image Nigel Parker This is one of my first Astronomy images ,as New to this Awesome Hobby , The commet took some finding , Unfortunately # 21ps closest approach it was cloudy , clear Skies Nige ;_))
The afternoon on the 19th of Dec. 2024, I observed this beautiful show of sharp and colorful parhelia. I had the Tamron 150-600 mm lens with me so, I captured some close-ups from these beauties.

Track lights reflected in the iridescent screen of an iPhone, for Flickr Friday’s #DepthOfField theme. The sharpest view of the iridescence comes from focusing on the light source, not the reflecting surface. Reflections of closer objects are less well focused. Note how the colors vary with angle, warmer on the left, cooler on the right. Rotating the phone also changes the colors, which can shift from rainbow to all blue or all red.

The optics of Lindesnes lighthouse are really impressive. Glass clarity is impressive especially given the time it was manufactured in.
Well, I'm quite obviously still no portrait-photographer and this lens isn't close to what anyone would consider sharp... and yet, I really like the look it creates. There could be more interesting subjects for sure… perhaps one day, who knows.
Oh, by the way: that lens is likely somewhere between 80 and 100 years old - it‘s really hard to say for sure, but I‘m trying to find out.

I photographed the Andromeda Galaxy on a recent camping trip.
(Video: youtu.be/yu8WZfb4nGk)
The image include 67 x 2-minute exposures at ISO 800 using a Canon 60Da DSLR camera.
The telescope used was a William Optics Zenithstar 73 APO, which is quickly becoming one of my all-time favorite scopes.
Unlike when shooting from home, I was able to swap a light pollution filter for a UV/IR to collect natural colors. Man, so much more enjoyable to process!

Thanks for looking!
Ian and I took over a small hallway off the lobby of a hotel taking bokeh shots of this art type display on the wall. I kept expecting an employee to come over and say ok enough is enough but they let us be.
