Object Details: The Owl Nebula (Messier 97) is a planetary nebula lying approximately 2000 light-years from Earth. Nearly 2 light-years in diameter, it is the result of the expulsion of material from a dying star and consist of three concentric shells. The inner shell is 'barrel-shaped' and oriented at approximately a 45 degree angle, so that from Earth we see the ends which appear darker and make up the owl's 'eyes'. Estimated to be about 8,000 years old, it spans just over 3 arc-minutes in our sky (i.e. ~ 1/10 the apparent diameter of the moon) and can be found in the constellation of Ursa Major. Glowing at magnitude 9.9, the nebula contains an extremely hot 0.7 solar mass white-dwarf central star which shines at 16th magnitude and whose temperature is estimated to be 123,000 K (by comparison our Sun's temperature is 5,778 K).
A composite containing a wide-field image showing the Owl, as well as the nearby Surfboard Galaxy (M108) can be found at the link attached here: www.flickr.com/photos/homcavobservatory/48892418878/
Image Details: Taken by Jay Edwards at the HomCav Observatory on March 27, 2019 using a Canon 700D DSLR and an 8-inch, f/7 Criterion newtonian reflector, the attached is a stack consisting of 55 minutes of total exposure time (excluding darks, flats and bias frames). The scope was 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.
Stacked using DeepSkyStacker and processed in PixInsight and PaintShopPro, as presented here it has been resized down to HD resolution and the bit depth has been lowered to 8 bits per channel.
Object Details: M101 is a face-on, grand design spiral galaxy lying approximately 21 million light-years from Earth.
Containing the equivalent of 1 trillion solar masses, it spans about 170,000 light-years from edge-to-edge.
Fairly large, it appears over 28 arc-minutes in diameter in our sky (i.e. approximately the size of the full moon),
and can be found in the constellation of Ursa Major.
The attached composite shows two views of M101 - a 'wide-field', taken with an 80mm apo & a 'close-up' taken with an 8-inch, f/7 newt. Many other smaller & fainter galaxies can be seen in both images.
In 8-inch image, at the very edge of the frame just above center can be seen NGC5477, a round galaxy glowing at magnitude 14.2, while at M101's 7 o'clock position (lower right of the brightest star in the frame) lies MCG9-23-25, a lenticular galaxy with a magnitude of 14.9.
Taking in a much larger portion of our sky, the 80MM wide-field image includes several others. In that image, at M101's 4 o'clock position is NGC 5474, a peculiar galaxy of a fairly rare category known as a dwarf spiral. Being the closest companion galaxy of the M101, NGC 5474's gravitational interaction with the much larger M101 has distorted it, resulting
in the disk being off-center to the galaxy's core. This 'lopsided shape' being quite evident in
the attached shot.
Given the orientation of the 80MM vs. the 8-inch images, NGC 5477 visible in the 8-in shot can be found near the 6:30 position in the 80mm image. To it's left are the round galaxy NGC 5473 at mag. 12.5, and below that the slightly larger and brighter NGC 5485; another round galaxy ,in this case at mag. 12.4, with NGC 5486 at mag. 13.8 at it's lower left.
To M101's upper left at the 10 o'clock position can be found NGC 5422. At mag. 12.8 it is a very elongated galaxy with a (relatively) bright core. Seen here somewhat edge-on,
it is classified as a type S0, which is an intermediate form between an elliptical and a spiral.
As a bonus, visible at M101's 5 o'clock position near the bottom of the frame (and unbeknownst to me at the time) - one of the 80mm subs also captured a meteor flaring as it passed through our atmosphere.
M101 is often referred to as the Pinwheel galaxy, it shares that moniker with the galaxy M33 in Triangulum.
Images of M33 can be found at the following links -

Image Details: The attached images were taken Jay Edwards on March 26, 2019 simultaneously using (left) an 80mm f/6 triplet apochromatic refractor (ED80T CF) connected to a Televue 0.8X field flattener / focal reducer and (right) a vintage 1970 8-inch, f/7 Criterion newtonian reflector. The 80mm was piggybacked on the 8-inch, and the scopes utilized twin (unmodded) Canon 700D / t5i DSLRs.
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.
The attached composite image was constructed using fairly small stacks of short sub-exposures, and consists of only 42 minutes total exposure for the 80MM shot (i.e. 14 subs of 3 mins. each) & 45 minutes (45 of 1 min ea.) for the 8-in image (both in addition to applicable dark, flat & bias frames).
Processed using a combination of DeepSkyStacker, PixInsight and PaintShopPro, as presented here it has been re-sized down to HD resolution and the bit depth has been lowered to 8 bits per channel.
Given the relatively short exposures used I was fairly pleased with the results, and am hoping to capture deeper images this coming spring (as well as taking a little less than 8 months before first examining them ;) ).
Happy Thanksgiving To All! (where applicable)

Here's Comet C/2014 Q2 (Lovejoy), which is currently visible in the evening sky. This image, which was captured through gaps in the cloud from Warrill View, south west of Brisbane. I'm not convinced that I could see the comet with naked eye, but it was very easily found with my 7x50 binoculars. This untracked image is 11 x 3 second exposures (taken with a tripod-mounted Canon 6D and 70-200mm f/4L at f/4 and 12800 iso), stacked using DeepSkyStacker. The tail is faintly visible towards the top of the image.
A wide-field view of the Milky Way stretching from the constellation Sagittarius (The Archer) northward to the constellation Aquila (The Eagle). This photo reveals many of the dark nebulae and interstellar dust clouds that obscure both the center of our galaxy and the star clouds that form the spiral-shaped disk of the Milky Way (seen edgewise from our solar system's location in the galaxy).

Believe it or not we got a clear night down here a couple of days ago. Just two hours before the clouds rolled in again at 2am, but enough time to do 40 x 2 minute subs on this thing. First widefield of the season :) A little overcooked but I'll give it more time if the clouds ever go away. Nice to see the Crescent - more by chance than design :)

M27, also known as The Dumbbell Nebula is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years. It was the first such nebula to be discovered, by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and diameter of about 8 arcminutes, it is easily visible in binoculars and is a popular observing target in amateur telescopes.

Here, NGC 884 and 869 are shown. Commonly reffered to as "The Double Cluster", these two Open Star Clusters are reletively close to Earth within our Milky Way. The two lie in the constellation of Perseus. The Double Cluster is a naked eye object for some depending on age and location. Personally, NGC 884 and 869 are two of my favorite objects to look at. Because they are so large, most telescopes have to use low power magnification to veiw them, which makes the young hot stars really POP out from the background sky. Each star can be resolved, looking like a cloud of diamonds against the charcoal gray of the night sky.

Open star cluster NGC 559 in Cassiopeia.
3,700 light years from Earth and at over 2 billion years old.
It's estimated to contain between 50 - 100 stars within the cluster. It can be seen with a medium to large telescope, big binoculars also if your lucky enough to have very dark skies.
I made the mistake of not guiding. As I thought I wouldn't need it as I was only taking 50 second exposures. My polar alignment wasn't the best and my collimation was a little out, noticeable in some elongated stars. It shows up more as I've cropped it quite heavily. The bigger you're reflector the more often it needs collimating I find.

taken with my Nikon d3400 on my celerstron evolution 9.95 telescope light pollution filter and focal reducer.20 images and 25 darks stacked in deepskystacker, and finally a good image .There is just so many pitfalls from telescope alinement ,good focus ,under or over exposure ,cloud turning up part way through what you are doing or skystacker rejecting your pictures.
