April 13th was a  good clear and dark sky which found the Sunflower Galaxy beckoning me.  I had a good run with nice tracking that produced 35 select frames at 300 second each for nearly 3 hours of integration time. 

“it appears to have an indeterminate number of spiral arms bound closely together, and is what’s known as a flocculent spiral galaxy. 

In fact, the Sunflower Galaxy only really has two spiral arms, but they are wound tightly round and round the galactic core, giving the impression of numerous arms.

The galaxy’s tightly-wound arms and bright center are what give the Sunflower Galaxy its floral appearance.”

A classic image from June 26th with a great night running from full dark till the sky started to get morning dawn. Perhaps my largest stack to date with 36 frames or 3 hours total integration time.

“The Pinwheel Galaxy is a face-on spiral galaxy 21 million light-years away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.”

From June 21st I captured only 10 good frames for a 50 minute stack. The nebula is in the lower left quadrant.

“The Elephant’s Trunk Nebula is over 20 lightyears long and can be found running through IC 1396, a young star cluster embedded within a cloud of glowing, ionised gas in the Cepheus constellation.
The Elephant’s Trunk is composed of cool interstellar dust and gas, which blocks out light on its way to Earth and leaves behind a long, thin silhouette that gives the nebula its name”

Elephant Trunk Nebula

This is a large and bright winter time emission nebula that is very rewarding to photograph. I last imaged this nebula three years ago with much the same story as far as the long pause at getting out to the telescope with winter season delays. Last night presented ideal conditions and produced this run of 32 five minute frames. Just the sub frames on the computer screen were impressive as they were coming in. Temperature was in the teens and the frost was not too bad as the evening progressed. I ended the run around midnight, as the telescope was near the end of its reach past the meridian and it was getting low in the sky.

5000 light years away, the Rosette Nebula contains an open cluster of 2500 young stars which are closely associated with the nebulosity, having been formed from the nebula’s matter. The most active region has plasma thought to be 100 to 1000 times hotter than a typical nebula, which we see as red light from hydrogen emissions. These high temperatures are thought to be the influence of more than one of the rare and massive O-type stars.  This nebula is some 130 light years across. 

Rosette Nebula 2022

Almost one year ago to the date I imaged this nebula with twice as many sub exposures but at a shorter exposure time. In this case I stacked 10 subs at 6 minutes each on a dark night with a bit of a breeze. Tracking was nothing to brag about but the stacked image seemed decent. I have learned much more in the processing side of this hobby and my third run through Photoshop resulted in a nice image shared here. Not a lot of the surrounding dark parts brought out in this version but a vibrant and detailed core I think.

Below is the original stack image pre processing for comparison. 

     Had a chance to get a couple of quick test shots with a new (to me) Canon SL1 at the backyard Astronomy Plaza. Some Christmas lights are on in the evening but they are OK during my setup, and turn off before I get serious. These are single exposures of 10 to 15 seconds so nothing fancy, but I like all the color and light effects.
