This is the latest project of mine captured from GrandMesaObservatory.com in Western Colorado and first light images using the Sky-Watcher Esprit 150mm ED F7.0 Triplet APO Refractor that Sky-Watcher USA have sent to us for testing.

I acquired the data in Color using LRGB Filters and I added H-Alpha to the red channel and as a luminance layer. For the Hubble Palette image these were captured using Chroma 5nm filters, Ha was binned 1x1, OIII and SII binned 2x2.

I’m very impressed with the Sky-Watcher 150 Esprit, using the big chip QHY16200A CCD Monochome camera with an OAG the Esprit 150 gives a very sharp image and a nice flat field, (Sky-Watcher quote a 43mm image circle), although a little slower than the TAK130, image quality is superb and unlike many APO refractors I have owned or tested the Esprit has a dedicated Field Flattener/corrector. For Autofocusing we purchased the Starizona Micro-Touch stepper motor which slips onto the dual speed side of the focuser, I’m using TheSkyX @ focus 3 for autofocus and it works great.

The Bubble Nebula (NGC 7635)

NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52 which can be seen in this image upper left. The "bubble" is created by the stellar wind from a massive hot, 8 magnitude young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel

Taken with a Skywatcher ED80 Refractor with a Canon 600D at prime focus. Best 20 of 40 images stacked with Autostakkert 2. No filters used. Average seeing but most frames had light fast moving cloud in them which causes stacking problems due to the varying brightness of each frame. Registax 6 failed to achieve a clean stack due to this I think. Could have easily removed the tinges of false colour but liked it better this way . None of the single frames had any false colour whatsoever so putting this down to seeing and cloud. Going to check the ED80's focuser alignment tomorrow though all the same as haven't checked it for 3-4 years :-) The Lens cell is not collimatable on this scope.

NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus.

The Crescent Nebula, located near the middle star that marks the heart of the constellation Cygnus, is a complex arc of gas that’s powered by the machinations of a massive dying star. Called WR 136, this star is just 4-5 million years old, but it’s big enough to have quickly burned through its store of fuel in its core and has now entered a stage where it sheds mass from its outer layer at a prodigious rate, nearly one full solar mass every 10,000 years. This fast-moving hot gas, which moves at a speed of 2,000-3,000 km/s, collides with cooler gas ejected by the star during its quieter days, and the collision excites the gas to emit light. Massive and mass-losing stars like WR 136 are called Wolf-Rayet stars. There are only about 150 such stars known in the Milky Way.

 

WR 136 will eventually detonate as a supernova when it finally runs of fuel and collapses. The explosion will obliterate the nebula and most other material within several dozen light years of the star. In its place will be a new type of nebula called a “supernova remnant” that consists of a rapidly expanding shock wave that excite the scant atoms lingering in the interstellar medium.

 

The location of the Crescent Nebula near the star Sadr in the constellation Cygnus, spread out over about 25 light years and lies at a distant 4,700 light years. It’s sometimes called the “Euro” nebula because of its resemblance to the symbol for the currency.

My 4th and best attempt at M51 although not happy that I had to go to ISO3200. My guide scope was causing me problems which I couldn't seem to sort out quickly. So rather than waste time I decided to go with the higher ISO ( yeah desperate !) to at least acheive something. Of the 91 subs I discarded about 10%

Nébuleuse de l'Iris - NGC7023

The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula and The Spire) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745–46. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula,[3][4] an area made famous as the "Pillars of Creation" imaged by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the aforementioned Pillars of Creation. The Eagle Nebula lies in the Sagittarius Arm of the Milky Way.
