Well I did get a pretty cool present from my daughters and their significant others for Christmas. It is the Star Adventurer tracking mount for taking night photos of the sky.
So I spent the past few days reading up on how to use the unit, make sure it was calibrated and then aligning it properly with the north star so that long exposures can be taken of night sky elements.
Finally had a clear night to try out the alignment with Polaris which turned out pretty cool. Then mounted my 300 mm lens on the Canon 7D Mark II to try it out taking some photos of Pleiades, a formation of baby stars in the sky.
Given there were some thin clouds and moisture haze in the sky as well as a near quarter moon adding light that would be better off not there, and taking this from my yard in Baltimore County which is not even close to a 'dark' sky ... it was some cool practice to see that I was able to get the unit aligned correctly so that 1 to 3 minute exposures could be done. It was able to even pick up some of the gas there around the stars even under the partial moon and city lights impacting the sky.
This capture here was at ISO 800 and just over 70 seconds, and at f/8 to get some star bursts.
Given I have enjoyed viewing this stellar object through a telescope many years before ... the amount of light being picked up here by the longer exposure is so much better than what the eye can see through the scope.
Looking forward to using it under much darker sky conditions ...
Three photo pano I took of the stars on the top of a hill with Mars looking real bright and pleiades also really visible to the left : )

Sorry about the chroma noise in the sky, dunno why It always appears on my uploaded photo but not on the actual photo I edited : (
The Pleiades star cluster, a night sky object that is pretty easy to see by eye currently! This is one night of data at Bendleby, 6 frames at 5 minutes each for red, green and blue filters, then the rest of the night with the luminance (monochrome) filter. RASA8 f/2 telescope, QHY268M camera, Celestron CGEM2 EQ mount, NINA control software, PHD2 guiding software, stacking and initial processing in APP, final processing in Photoshop. This target has lots of bright stars, which brings out the worst in my cable placement issues! Other than ugly stars, and more data needed for less noise, pretty happy with how this turned out!
The Pleiades taken this week during a surprise and brief period of dark skies and no clouds.
The Pleiades or Seven Sisters, catalogued as Messier 45, is an open star cluster of middle-aged hot blue B-class stars in the constellation Taurus, approximately 444 light years from Earth. The glowing blue nebulosity is thought to be an interstellar dust cloud, illuminated by the stars.
Light pollution from nearby Ocean City to Assateague really added to the scene over the marsh along the Maryland eastern shore. I liked the color version ... but the B&W really pops more I think.
Pleiades was also rising above the trees at the horizon.
The Pleiades, also known as Seven Sisters and Messier 45, is an open star cluster of young, hot stars burning blue. A gaseous cloud is passing between earth and the Seven Sisters, and the bright blue star light causes the gaseous cloud to glow. The cloud is moving quickly, so in 1,000 years Pleiades will no longer be sporting the delicate halo. While a common name might suggest that the Pleiades has 7 stars, a closer look reveals about 1,000 stars bound loosely together.
Another common name for this deep sky object is Subaru.

Happy Nice Wonderful Clouds Tuesday!
Took this late night capture under moonlight into black and white. Nice with Venus and Pleiades there in the sky too.

A first run at this object with my own setup, guided exposures. Guiding graph was quite exceptional with RMS error at 0.03" then later 0.07" but I tossed away 1/2 my lights over 2 nights due to some trailing at the edges. Discovered this was due to the reducer slightly unscrewed. Some high cloud in a couple of the shots made the seeing wobbly so guiding wasn't perfect all night. Will add more data next time we have clear skies. Everything was iced up after 2 nights outside in -4 deg C temps, but dew band heaters kept going. So did I by sitting indoors and watching it all on Teamviewer! I still have a little amp glow on the right from the 700D! Updated the HC and MC on the mount too, but still not totally satisfied with the way it is performing. Everything looks pretty tight but the Alt axis is still 'rocking' slightly in its locked position.

The Pleiades (also known as the Seven Sisters, the Chioccetta or with the initials M45 in the catalog of Charles Messier) are an open cluster visible in the constellation of Taurus. This cluster, quite close (440 light years), has several stars visible to the naked eye; even if only four or five of the brightest stars are visible from city environments, twelve can already be counted from a darker place. All its components are surrounded by light reflection nebulae, especially observable in long exposure photographs taken with large telescopes.
Remarkable is that the stars of the Pleiades are really close to each other, have a common origin and are linked by gravity.
Given their distance, the stars visible between the Pleiades are much hotter than normal, and this is reflected in their color: they are blue or white giants; the cluster actually has hundreds of other stars, most of which are too distant and cold to be visible to the naked eye. The Pleiades are in fact a young cluster, with an estimated age of about 100 million years, and an expected life of only another 250 million years, as the stars are too far apart.
Because of their brilliance and proximity to each other, the brightest stars of the Pleiades have been known from antiquity: they have already been mentioned for example by Homer and Ptolemy. The Disc of Nebra, a bronze artifact from 1600 BC. found in the summer of 1999 in Nebra, Germany, it is one of the oldest known representations of the cosmos: in this disc the Pleiades are the third clearly distinguishable celestial object after the Sun and the Moon.
Since it was discovered that the stars are celestial bodies similar to the Sun, it was started to hypothesize that some stars were in some way related to each other; thanks to the study of proper motion and the scientific determination of the distances of the celestial bodies, it became clear that the Pleiades are really gravitationally bound and that they even have a common origin.

"Pleiades" is an authentic working replica of an 1830 gaff rigged Eastport Pinky Schooner. Pinky schooners have a high pointed stern as shown here. When they were used for fishing in the 1800's they had a slot in the stern to wash out fish waste. This slot is very visible in the reflecxtion. The 55-ft pinky Pleiades was seen at the 2011 Wooden Boat Festival at Port Townsend, WA. woodenboat.org/plan-your-visit
L'amas des Pléiades, les Pléiades ou amas M45, est un amas ouvert d'étoiles qui s'observe depuis les deux hémisphères, dans la constellation du Taureau. L'exactitude de la distance de l'amas à la Terre fait débat. Cette distance, selon les différents instruments techniques utilisés, est estimée à environ 444 années-lumière. Elle contient NGC1432 et NGC1435.
The Pleiades (also known as Seven Sisters and Messier 45 (M45), is an asterism of an open star cluster containing young B-type stars in the northwest of the constellation Taurus. At a distance of about 444 light-years, it is among the nearest star clusters to Earth and the nearest Messier object to Earth, being the most obvious star cluster to the naked eye in the night sky.

Messier 45, Pleiades or, from my childhood days, The Seven Sisters.
At 444 lightyears from earth they are probably the best open star cluster in the sky. The bright young hot stars are thought to be passing through a dust cloud thus creating reflection nebulae. The clustering will eventually be lost due to local gravitational interactions.

The car carrier inbound from Rotterdam to the Tyne with three tugs in attendance. One tug is out of shot to the left.
For this image, two different setups were used. The data were taken at the same time and the same place.
We decided to shoot the same target, to combine our data.
The Omegon refractor is equipped with a riccardi reducer and therefore the exposures are shorter. There is a little more data on the 600 sec subs, but it is not that much.
Putting the data together really helped to bring out the background nebula a bit.

On Tuesday 1st April the Moon passed in front of The Pleiades (Seven Sisters, M45) star cluster. The occulatation lasted for few hours but I was only able to capture the hours leading up to and about 45 minutes of the start of the event. In this image you can see part of the cluster has already been covered by the dark side of the moon.
The Pleiades or Seven Sisters is an open star cluster in the constellation Taurus. The seven main stars are easily visible with the naked eye.
This is a reprocessed version of an image taken back in October 2023 which now reveals fainter dust surrounding the main stars.
