16 frame stack 32 minutes exposure of the summer Milky Way imaged from the an elevation of 2877 metres at the summit of the Pic Du Midi Observatory, France. I used a modified canon 50d and a Canon 15mm fisheye lens stopped to F/4 and iso 1600. A vixen Polarie was used to track the stars. Image acquired July 2013

This 12.5hr exposure peers deep inside the Great Nebula in Orion. The ionisation of Hydrogen atoms by ultra violet radiation, emitted by massive stars deep inside the nebula, produce the predominantly red hues. Clouds of fine dust appear blue-grey due to the scattering of short visible light wavelengths in a process known as Rayleigh scattering. Cold foreground dust and dark molecular hydrogen create a fine intricate web of obscuring dark clouds. The combined atomic and optical processes coordinate to produce this stellar kaleidoscope of wispy details and colours.

I tried some of the standard Ha combine techniques and I winded up using a blend of several different again.

 

Not that it added a ton over the regular LRGB but maybe a bit of punch and color.

 

I again merged the data from my 180mm ED lens with data from my ED80 from around M42 and the Horse Head for better detail in those areas.

....yet another drum scan done of negative 17 on my Fuji Superia ISO 800 negative film done in Dallas Texas. Notice the film sprockets picked up by the drum scanner as it was oil mounted to the plastic cylinder during scanning, they are visible along the top and bottom of image just at the edges...........good old fashioned film!!!!! Can't beat it!!!!!

This is a close up view of an interesting area inside the Rosette Nebula. NGC 2237 is a large, circular hydrogen region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster, NGC 2244, is closely associated with the nebulosity, the stars having been formed from the nebula's matter. The Nebula is about 100 light-years across and is about 5000 light-years away.

 

The image was created using the Hubble palette, with SII, Ha and OIII filters mapped to red, green and blue respectively. The colors were then adjusted to create the blue and gold motif, made popular by the Hubble Imaging Team.

NGC 7380 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). Known as the Wizard Nebula, this object is a reasonably large nebula located in Cepheus.

On January 1, 2014 I had another go at Comet Lovejoy with the iTelescope 20" astrograph. The data I got back this time, however, was a lot better due to near perfect sky conditions. Exposures: L=4x120Secs, RGB=2x120Secs.

This is a reprocess of last years image. 2min subs, approximately 80 mins total of data. I added a bunch more darks and processed this with pixinsight.

I shot this while on vacation in the California Bay area last year. This part of the sky doesnt even rise above the horizon in my home town of Seattle.

 

I used a canon 70-200 2.8 IS II lens wide open at 200mm. As you can see the lens is pretty good even wide open. There is a small amount of false color visible at full size but I think part of that is caused by the interaction with the LP filter I used (astronomik CLS-CCD) especially at F2.8.

The Great Orion Nebula, or Messier 42, is one of the few deep sky objects that can be readily seen with the unaided eye. Seen as a "fuzzy" star in the sword of the winter constellation Orion, this massive star forming region is approximately 1300 light years distant. The nebula was recognized by the ancient Maya, and is now one of the most photographed and studied deep sky objects by amateur and professional astronomers alike. This image was taken from near Moorook, South Australia and comprises 9 hours of data collected through a thermoelectrically cooled astronomical KAF-16803 based CCD camera. LRGB and hydrogen alpha filters were used in data collection.

There are a lot of firsts for me in this image. First deep sky image from a dark sky (SQM 21.3 on this night), first image with new camera (SBIG STF-8300C), first time automating entire imaging run (via ACP), and first time combining images from multiple nights. It's also the first time I've done the majority of processing in PixInsight. So much to learn in this hobby!

 

Full acquisition and equipment details here.

Multiple image stack Comet C/2011 L4 (Panstarrs) made with a Canon 5d mkII and a Canon 135mm prime lens at F/4. Exposures were 1sec each and iso was 1600. In total 2 minutes and 20seconds of data was accumulated and processed in Photoshop CS5.

This region lies in the constellation of Sagittarius around 5,800 light years away. It has a bit of everything. It's embedded within the rich star fields of Sagittarius and contains dark, emission (red / pink) and reflection (blue) nebulae. The area encircled by the dark lane contains at least 7 catalogued objects - IC 1274, IC 4685 (the large reddish nebula below center), NGC 6559, GN 18.06.6.01, Barnard 303, Barnard 91 and IC 1275. The two brightest reflection nebulae are NGC 6559 (to the bottom- south) and IC 1274 (to the top - north).

 

This is an (L+Ls)RGB image (150+90, 90, 90, 90 minutes). Total of 7 hrs of data. LRGB subs were 15 mins in duration. All channels unbinned. FOV is 47 x 69 arcmins.

 

It was taken with a Takahashi TOA-150 refractor @ F7.3 (FL=1095mm) using an SBIG STL 11000M camera and Takahashi 67 flattener.

In questa immagine ho "osato" forse troppo combinando frame provenienti da strumenti troppo differenti (da un 75mm ad un 408!).

Anche se le differenze di dettaglio e contrasto sono palesemente evidenti, mi pare comunque gradevole. Mi riprometto di riprendere le parti lowres quanto prima con una risoluzione più adeguata.

I tempi di questa HaLLRGB sono di circa 320min complessivi con ottiche diverese (rifrazione/riflessione) e diversi CCD.

A beautiful panorama of an area of the constellation of Orion that almost resembling a true stellar landscape, from the 3 famous stars of the belt to M42.

6 hours of Ha data captured over 2 nights during a fullmoon. Qhy9m 34x 700seconds 8"newt Heq5pro guided with dmk 21mono, captured and guided with Maxim DL processed with Maxim and PS cs5.

An experiment to try to push exposure times, i felt i have not really produced a deeper image of a dso as yet due to data acquisition limitations of work and suitable environment. Hopefully with a permanent set up and a quality camera capable of limiting light pollution issues and a good match of scope to camera , I can produce some more satisfactory results.( As a side note: and probably not a surprise for seasoned photographers), The single Ha image I captured a few nights previous to this session, before windows updated and shut down the laptop grrr.. had stunning clarity and contrast that in 700 seconds has about half of this 6 hour versions quality already. Impatiently waiting for a new moon and good transparency.

I prefer this version. What do you think?

The Leo Triplet (also known as the M66 Group) is a small group of galaxies about 35 million light-years away in the constellation Leo. This galaxy group consists of the spiral galaxies M65, M66, and NGC 3628.

 

I managed to get a tiny hint of the tidal tail coming off NGC 3528, if you squint you can see it.
