7000 light-years distant in the constellation of Cassiopeia lies the emission nebula colloquially known as the Soul Nebula. The gasses (mostly hydrogen) that comprise the nebula are being ionized by the stars within the region and as a result, the gasses glow, much like a neon sign.
The pressures exerted upon the material by the stars nearby are causing the material to become compressed. When enough of the gas becomes highly compacted, it triggers the birth of new stars. In effect, this is a beautiful snapshot of a multimillion-year process of an enormous cloud of dust and gas transforming itself into new stars.

NGC7822 is a spectacular example of a stellar nursery. The emission nebula shines as a result of the ionizing radiation from one of the hottest stars known; BD+66, which has a luminosity 100,000 times that of our sun. Curiously enough, BD+66 is also an eclipsing binary, which means that it is actually two stars in orbiting each other and are aligned in such a way that one star occasionally eclipses the other from our perspective.
NGC7822 is a very young star forming region; no more than a few million years old. It will continue birthing new stars for several million more years until the radiation from the new stars blows away the last remnants of hydrogen gas, leaving behind a small cluster of young bright stars.

Hi Friends
Since I acquired my latest Paramount GT1100S GEM I haven’t been able to use it due to a problem finding home position but the removal and replacement of the homing sensor on the right ascension drive that we found to be broken and causing the problem is now completed.
I wanted to bench test the mount before reinstalling on the pier in the observatory, just how do we do that when there is no telescope or counter weights on there to balance?. You will see in the pic attached that we had to compromise using a bottle of Minute Maid fruit juice for the counter weight (if you ever plan on trying this the bottle must be full) For simulation of the telescope we selected a 2.5 pound hammer. How hi tech is that!!! The balance was of course slightly east heavy. Adam is seen getting ready to flick the switch.
I went to bed at 7am this morning with a feeling of major accomplishment, I believe I am the only person to ever have dismantled the GT1100S and re assemble outside of Software Bisque and I now have the TMB 130 on it mounted back on the pier, everything is working great. It goes to home position every time and is tracking without error whether using the joystick or using thesky6 on my PC.
All the work was carried out on the island bench in our kitchen, thanks to my loving wife Christyna for being patient with me. I want to thank both Alan (my step son) and Adam Stirek of www.castle-emerald.com and Newaygo County Dark Sky Astronomers for their personal help at the house and also you blokes (my friends) especially my imaging partner Andy and also Cliff for much help and support getting me through this on the phone and by emails.
All the Best

It’s not me that has a hobby, its my camera
Known as The Omega or Swan Nebula and also The Checkmark, Horseshoe and Lobster Nebula (wow a lot of names).
Another object which for me is very low in the south and I'm not sure if I will be able to complete imaging this target this year as it is quickly sinking to the western horizon.

5000 light-years distant, toward the consellation Sagittarius, lies the spectacular Omega Nebula, also known as the Swan. The nebula istelf spans an incredible 40 light-years and contains a whopping 30,000 solar-masses worth of hydrogen gas and dust. The gasses are being compressed under both gravity and the pressure from stellar radiation of newly born stars, and will continue birthing new stars as the hydrogen becomes hot and dense enough to undergo nuclear fusion.
M17 is one of the most prolific of known stellar nurseries. Already having birthed 800 or more stars in the last million years, it will continue creating stars for the next several million years. When the last remnants of gas have either been used up in the formation of stars or swept away by the intense radiation from these new stars, it will leave behind a dense cluster of thousands of hot, bright stars.

I was quite amazed at the level of detail in this so I decided to post a crop of just M17.
We currently have very bleak conditions here in western michigan with snowfall expected tonight, the only chance I will have of shooting more of M17 this year is if I sell my house and most of my equipment and move back to Australia, get myself a portable mount and go live in the Outback .....ahhh I'm tempted!! :)
