Description: This gallery shows four planetary nebulas from the first systematic survey of such objects in the solar neighborhood made with NASA's Chandra X-ray Observatory. The planetary nebulas shown here are NGC 6543 (aka the Cat's Eye), NGC 7662, NGC 7009 and NGC 6826. X-ray emission from Chandra is colored purple and optical emission from the Hubble Space Telescope is colored red, green and blue. A planetary nebula is a phase of stellar evolution that the sun should experience several billion years from now, when it expands to become a red giant and then sheds most of its outer layers, leaving behind a hot core that contracts to form a dense white dwarf star. A wind from the hot core rams into the ejected atmosphere, creating the shell-like filamentary structures seen with optical telescopes. The diffuse X-ray emission is caused by shock waves as the wind collides with the ejected atmosphere. The properties of the X-ray point sources in the center of about half of the planetary nebulas suggest that many central stars responsible for ejecting planetary nebulas have companion stars.

the “planets on parade” :Our solar systems “ 5 +1” naked eye planets. From the “fish eye view” focal lengths of 8mm to > 8000mm (2032 with 4x PowerMate for Mars mono)
Been a bit of a frustrating exercise (3 mornings @ 02h50 until dawn) … tried the 14” (unstable in windy morning breeze/ top heavy) – and ended up with the 8” (rock stable) – and with both tried different combinations of the Skyris 445C color cam and the Skyris 618m mono cam – with 2x and 4x PowerMates. Seeing not great ( or perhaps my lack of expertise and limited knowledge of Registax more of an obstacle…!) – be it as it may.
Especially Venus and Mercury were “contorting blobs” on the screen – the unstable morning air over build-up area and thick layer of atmosphere to shoot through not doing me any favours.
The only two images I am sort of satisfied with are the 2 mono-colours of Saturn and Venus – taken in the Karoo last year.
From its station nearly 1.2 billion kilometers (746 million miles) from
Earth, the stalwart Cassini spacecraft sends holiday greetings to Earth
with this lovely color portrait of Saturn and two of its moons.
The 2004 holiday season marks the close of a miraculous year that saw the
end of Cassini's long journey across the solar system and the beginning
of its adventures in orbit around Saturn. In a triumph of human
achievement, the Cassini mission has already returned thousands of images
and has begun to uncover the mysteries of the Saturn system. This color
portrait serves as reminder of the Saturnian places we have already seen
and the promise of future discovery at Titan when the European Space
Agency's Huygens probe arrives at Titan on Jan. 14, 2005.
The image shows the majestic ringed planet, with bands of colorful clouds
in its southern hemisphere. The planet's northern extremes have a cool
bluish hue, due to scattering of blue wavelengths of sunlight by the
cloud-free upper atmosphere there. Long shadows of the icy rings stretch
across the north.
A grayish, oval-shaped storm is visible in Saturn's southern hemisphere
and is easily 475 kilometers (295 miles) across - the size of some
hurricanes on Earth.
Titan (5,150 kilometers, or 3,200 miles across) is visible near lower
right with its thick, orange-colored atmosphere, and faint Mimas (398
kilometers, or 247 miles across) appears just right of the rings' outer
edge.
Images taken in the red, green and blue filters with the Cassini
spacecraft wide angle camera on Dec. 14, 2004, were combined to create
this color view at a distance of approximately 719,000 kilometers
(447,000 miles) from Saturn. The image scale is 43 kilometers (27 miles)
per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the
European Space Agency and the Italian Space Agency. The Jet Propulsion
Laboratory, a division of the California Institute of Technology in
Pasadena, manages the mission for NASA's Science Mission Directorate,
Washington, D.C. The Cassini orbiter and its two onboard cameras were
designed, developed and assembled at JPL. The imaging team is based at
the Space Science Institute, Boulder, Colo.

Alignment of the five bright planets, in order of their distance from the Sun, together with the waning crescent moon, as seen from Mout Coot-tha, Brisbane, Australia. The last time these five planets aligned was in 2004 and the next occurence will be in 2040. Mercury can be seen in the lower right, just above the pre-dawn glow. The other planets are aligned diagonally along the path of the ecliptic, first Venus, then the Moon, Mars, Jupiter and finally Saturn in the upper left corner. Six images stacked to a vertical panorama in Photoshop.
The year is 2099. As space exploration thrives, venturing into the cosmos has become commonplace. Nations and even private companies now have their own exploration teams. Among these pioneers are VAREC 02 and VAREC 07, designed and produced by the Vietnam Aerospace Research and Exploration Committee (VAREC).
Repurposed from a vintage 2022 John Deere skidder, VAREC 07 is equipped with a powerful front claw, built for collecting and transporting planetary rocks and meteor samples for advanced geological research. Supporting it is VAREC 02, a specialized maintenance robot tasked with repairs and upkeep, ensuring VAREC 07 operates at peak efficiency during every mission.

Object Details: This time of year in the Northern Hemisphere brings what many astrophotographers refer to as 'Spring Galaxy Season'. Having taken some shots of M65 & M66 at this time last year, as the first test images since re-opening the RoR observatory I built at my home here in upstate, NY after it's long winter slumber, I thought I'd try to complete the images required for the attached composite.
The Leo Triplet is a group of three gravitationally interacting galaxies consisting of NGC 3628 (left, aka 'The Hamburger Galaxy'), M65 (upper right) and M66 (lower right). All three galaxies are classified as spirals, and their structures are being disrupted as they gravitationally interact with each other. From Earth's perspective each is tilted at a different angle, with NGC 3628 oriented nearly 'edge-on' and thus showing a very prominent central dust lane bisecting the galaxy.
The group lies approximately 35 million light-years from Earth, and at that distance, the wide-field view shown at center covers approximately 2 million light-years in diameter, edge-to-edge. M65 has a diameter of approximately 90,000 light-years, M66 is slightly larger at 95,000 light-years while NGC 3628 is about 100,000 light-years in diameter (comparable to the diameter of our own Milky-Way).
Among other effects, their gravitational interaction results in the asymmetric spiral arms and off-center core of M66, caused by the combined pull of M65 & NGC 3628; as well as a 300,000 light-year long 'tidal stream' of stars trailing from NGC 3628, part of which is faintly visible to the lower left of the galaxy in the wide-field image. M65 & M66 each contain about 200 billion stars while NGC 3628 contains over 300 billion, with it's tidal stream alone consisting of approximately 500 million solar masses.
M65 & M66 lie about 160,000 light-years apart, which is comparable to the distance between our own Milky-Way and it's satellite galaxy The Large Magellanic Cloud. NGC 3682 lies over 300,000 light-years from the M65 / M66 pair and simulations of their movement though time suggest that NGC 3628 & M66 came within 80,000 light-years of each other 800 million years ago. The asymmetry of M66 & it's off-center core and the stellar tidal stream of NGC 3628 as well as other disruptions and asymmetries maybe be remnants of the result of this close encounter.
When I first noticed the 'mottled' appearance faintly visible though-out the wide-field image after stacking (most prominent on the lower right and the left sides), I thought it might be noise, yet it looked somewhat suspicious. When comparing it's relative location with very deep images of this region, it seems to align with the Integrated Flux Nebula (IFN) surrounding this area, which until then I did not know was even present in this region of the sky. For more detail regarding IFN, probably most often imaged around the M81 / M82 galaxy pair, please see the shot at the following link where it is much more prominent and thus 'easier' to image

Image Details: The attached images were taken Jay Edwards on March 21, 2020 and April 8th & 9th, 2021 and consist of a total of over four hours of integration time (in addition to the associated bias, flat & dark calibration frames).
Since I often shoot simultaneously using twin unmodded Canon 700D (t5i) DSLRs, the wide-field shot at center was imaged with an 80mm f/6 carbon-fiber triplet apochromatic refractor (i.e. an Orion ED80T CF) connected to a Televue 0.8X field flattener / focal reducer; while the individual shots of NGC 3628 (left) and M65/M66 (right) were taken with a vintage 1970 8-inch, f/7 Criterion newtonian reflector at prime focus. The 80mm was piggybacked on the 8-inch, and the cameras were controlled by APT. These optics were tracked using a Losmandy G-11 mount running a Gemini 2 control system and guided using PHD2 to control a ZWO ASI290MC planetary camera / auto-guider in an 80mm f/6 Celestron 'short-tube' refractor which itself was piggybacked on top of the 80mm apo.
Processed using a combination of DSS, PixInsight and PaintShopPro, as presented here the wide-field and 'close-up' images have only had their edges cropped slightly, and since they utilized identical cameras, they show the FOVs relative to each other for the 80mm & 8-inch rigs. After assembly the entire composite has been re-sized down to HD resolution (less than 1/6th it's original resolution) and the bit depth has been lowered to 8 bits per channel.
I'm hoping to re-visit this area in the future using one of my CCDs to emphasize the IFN permeating this region & the various gravitational disruption features within the galaxies themselves.
M57 The Ring Nebula, A Test for Deep Sky Work with a DMK21 & DMK31 Uncooled Planetary Video Camera.
M57 is a Dying Star that has blown off its outer Atmosphere!
I recently was asked by some DMK Monochrome Camera users if they could use it for more than the Sun, Moon, & Planets work....I decided to try it, but last night was a worse case scenario, using the DMK on a 10" scope, through sucker holes in the clouds, and high haze, poor seeing, stacking 10 x 32 second exposures through RGB filters.
Details:
My backyard in the city of Dayton, Ohio on 08-02-13
Prime Focus of a 10" diameter scope 1600mm FL, no autoguiding
DMK21AF04 Monochrome Fire-wire Camera, uncooled, ~ 65F
IC Capture Software using the "Capture Frame Sequence Mode" to capture individual images
32 second exposures x 10 images,
Astronomik RGB Filters (the same ones I use for planets)
320sec total per R, G, & B channel
Final total exposure time of 960 Seconds.
No Darks, flats, or Bias were applied, just raw data!
Stacked the individual monochrome images in "Nebulosity 2",
to end up with 3 separate image files a red, green, & blue.
Assembled the 3 Separate RGB image files in Adobe "Astro Actions" RGB mode.
Final color balance in Adobe.
Surprisingly the DMK camera is extremely low noise for being a non-cooled camera, even in longer exposures!!!
Yes, even in this worse case scenario it would work okay for Bright Deep sky objects like small bright planetary Nebula, bright Globular clusters, and even close double stars! The FOV is too small at this focal length for the large Nebula, but if you use a smaller scope or focal lengths under 800mm you can increase your FOV a bit for the DMK21 to grab those larger objects.
I also tried this on the DMK31 & DMK41 larger chip model, and used a .5x focal reducer and this increase the FOV quite a bit...so this would work for the bigger bright objects.
The answer is YES the DMK cameras can do Brighter object Deep Sky work!

Abstract inspired by the phrase "created order out of chaos". I have admired the effects achieved by artists that employ the technique of flow medium, but thought they relied too much on chance. They could use good judgment and halt the process when they chose, and they could choose the colors of their palette, but composition and adjustments were difficult.
Here I have chosen my palettes and their placement and structured my composition as intended. I have manipulated the forms to my liking, and I think I attained some of the complexity that is found in examples of flow art.
This was done in ImageReady.
During my garage sale travels today I saw a set of wrapped bath salt pressed into these pink balls. Three balls, three tries.
I also got another RF camera trigger in the mail for my Nikon D7000. A few months ago I bought one for my Canon because my existing IR control didn't trigger too well.
The trigger is a cheap unit that I had to rework to add a switch for the transmitter. It uses those expensive 12 volt batteries and since it did not have an on/off switch, the battery would drain after a few weeks.
With two receivers I decided to try setting up two cameras for each shoot. It adds some complications but what the hell, this hobby is all about complications.
So this is a picture of the bath salts from the angle of the air cannon. Lots of shadows compared to the normal view.
Cheers.
