After another night of collimation, the setup is getting closer to a workable state. It's surprising how awake you stay the whole night when temperatures are again in the freezing portion of the scale.
I'm setting up a Teleskop-Service version of Boren-Simon PowerNewt 8 f/2.8. Actual focal length is now 604mm, which makes it an f/3, but still a bit of an improvement from the C8+Crayford+reducer f/7.
The small pixels of the camera in use (Trius SX814) are perhaps a bit too small for the ASA Keller reducer drawing capabilities.

Description:
From the heart of Desert Bloom Observatory, the night unveiled the ethereal dance of the Pleiades (M45)—a cluster of radiant sisters bound by gravity and myth. Draped in silken blue veils of cosmic dust, these stars shimmer across the constellation Taurus, about 444 light-years from Earth. Their reflection nebulae are illuminated by scattered starlight across interstellar dust—an elegant harmony between myth, matter, and light.

Alcyone is the brightest star in the Pleiades star cluster (M45). The nebula is dust leftover from the formation of the stars. It appears blue for the same reason that the sky is blue. 10 minute total exposure at f/6.3 with a Celestron Edge HD 9.25" and ATIK 314L+ color CCD camera. Guided with PHD.

Cradle of Cosmic Beginnings — The Embryo Nebula (NGC 1333)
In the quiet vastness of the Perseus Molecular Cloud, NGC 1333 — the Embryo Nebula — stirs with the breath of creation.
Glowing softly in hues of blue and amber, this reflection nebula shelters newborn stars wrapped in cocoons of cosmic dust. Their faint light dances through veils of interstellar mist, whispering stories of stellar infancy. Captured over five patient nights at Desert Bloom Observatory, this image gathers 88 frames of 600-second exposures — a tapestry woven from light and time. Every pixel speaks of formation, turbulence, and renewal — a glimpse into the universe’s eternal cycle of birth and becoming.
NGC 1333, located roughly 960 light-years away in the constellation Perseus, is a dense star-forming region within the Perseus Molecular Cloud Complex. It is dominated by reflection nebulosity — dust illuminated by young, hot stars — and marked by dark filaments and Herbig–Haro objects, where stellar jets collide with surrounding gas. The region teems with protostars, brown dwarfs, and protoplanetary disks, representing one of the most dynamic laboratories for studying early stellar evolution. The nebula’s distinctive structure resembles an embryo in a cosmic womb — a symbol of the universe’s relentless creativity.

Just weeks after NASA astronauts repaired the Hubble Space Telescope in December 1999, the Hubble Heritage Project snapped this picture of NGC 1999, a nebula in the constellation Orion. The Heritage astronomers, in collaboration with scientists in Texas and Ireland, used Hubble's Wide Field and Planetary Camera 2 (WFPC2) to obtain the color image. NGC 1999 is an example of a reflection nebula. Like fog around a street lamp, a reflection nebula shines only because the light from an imbedded source illuminates its dust; the nebula does not emit any visible light of its own. NGC 1999 lies close to the famous Orion Nebula, about 1,500 light-years from Earth, in a region of our Milky Way galaxy where new stars are being formed actively. NGC 1999 was discovered some two centuries ago by Sir William Herschel and his sister Caroline, and was cataloged later in the 19th century as object 1999 in the New General Catalogue. This data was collected in January 2000 by the Hubble Heritage Team with the collaboration of star-formation experts C. Robert O'Dell (Rice University), Thomas P. Ray (Dublin Institute for Advanced Study), and David Corcoran (University of Limerick).
My updated image of NGC2023; the emission/reflection nebula between the Flame Nebula and Horsehead Nebula in the constellation of Orion. The big star you can see in the top left corner of the picture is Alnitak - the first star in Orion's Belt. At a distance of just under 1700 light years, this is the largest nebula of its type ever discovered. Despite this, it doesn't have a name.
The Iris nebula (NGC 7023) is a reflection nebula in the constellation Cepheus. Reflection nebula means that there are common clouds of interstellar dust that reflect the light of a nearby star. In this case, it's a very young star SAO 19158, which is only about 5000 years old. Iris nebula was discovered by William Herschel in 1794. It's approximately 1400 light years away and it has 3 light years in diameter.

Sh2-279 (alternatively designated S279 or Sharpless 279) is an HII region and bright nebulae that includes a reflection nebula located in the constellation Orion. It is the northernmost part of the asterism known as Orion's Sword, lying 0.6° north of the Orion Nebula. The reflection nebula embedded in Sh2-279 is popularly known as the Running Man Nebula. Sh2-279 comprises three NGC nebulae, NGC 1973, NGC 1975, and NGC 1977 that are divided by darker nebulous regions. It also includes the open cluster NGC 1981. The brightest nebulosity, later listed as NGC 1977, was discovered by William Herschel in 1786. He catalogued it as "H V 30" and described "!! 42 Orionis and neb[ula]". The two smaller reflection nebulae were first noted by German astronomer Heinrich Louis d'Arrest, NGC 1973 in 1862 and NGC 1975 in 1864.[5] All three were included in the New General Catalogue in 1888.[6] The designation NGC 1977 is used in various sources for the reflection area around 42 Orionis (the south-east portion of the reflection nebula), for the entire reflection nebula (including NGC 1973 and NGC 1975), or for the whole nebula complex.
An attempt at an hour of exposure of reflection nebula #messier78 through intermittently cloudy skies. This fuzzy patch is just to the upper left of Orion's belt. This one is proving tricky. I think I need about 3 hours to really bring our detail and color for this one. #astrophotography #deepskyphotography #messierobjects #reflectionnebula
NGC 1973 (Running Man Nebula) is a reflection nebula associated with Orion’s molecular cloud. The nebula is located just .5 degree north of the Great Orion Nebula and 1,500 light years away from Earth. The blue color derives from the interstellar dust that reflects the light from the surrounding young stars. The image consists of 75 x 5min exposures taken with a Canon 60Da and TPO 8” RC telescope mounted on a Celestron CGE Pro mount. Images were stacked with Nebulosity 4 and processed with PixInsight 1.8
Blue Horsehead Nebula, also known as the IC 4592, is a reflection nebula located in the constellation Scorpius. The nebula is illuminated by the star Nu Scorpii, which is part of a multiple star system, and the radiation from this star causes the interstellar dust in the nebula to shine with a bluish hue, characteristic of reflection nebulas. IC 4592 is situated approximately 400 light-years from Earth.
This nebula is notable for its distinctive shape, which resembles the head of a horse. Unlike the famous Horsehead Nebula in the constellation Orion, which is an emission nebula, IC 4592 shines by reflecting the light of nearby stars. The nebula extends over several tens of light-years and is an interesting region for astronomical studies due to the interaction of starlight with interstellar dust and gas.
