A new image has been posted! (M20)

Hi all!

 

A new image has been uploaded! This time, it concerns M20, the Trifid Nebula. There was already another image of M20 in the web site, but this one has a couple of characteristics that might improve the previous one. Firstly, it is mainly a narrowband image (compared to the usual LRGB images of this object), and secondly, in order to get a more “real-natural” image, broadband Blue images have been blended with the OIII frames, in an attempt to capture all blue nebular wisps. The narrowband filters allow for a better contrast/resolution. Judge for yourselves:

NGC 104, Caldwell 106, 47 Tuc

Hi all,

A new image has been uploaded! This time, another globular cluster (taken when the Moon was full and too close to the nebulae I was imaging…). This image has been taken in HDR (more info in the web site) in order to capture individual stars down to the center of the cluster. It can be found at:

M 27 reprocessed. A definitive version

Hi all,

 

A reprocessed version of M 27 (taken with the astounding Schulman Telescope, 32″) has been uploaded. This version has been reprocessed giving a higher importance to the RGB and a bit (just a bit…) less to the H alpha. The same subframes have been used and it is only a very different way of interpreting the image. I think it is worth to give a look at it:

NGC 3576 uploaded!

Hi all,

 

A wonderful nebula has been uploaded. NGC 3576 is an emission nebula in the constellation Carina. This image has been taken in narrowband (Ha, OIII and SII), by my telescope partner Don Goldman, whom I am thankful for allowing me to use and process this image. The processing has been, as usual, trying to reproduce the original visible spectrum of this nebula. More about it here:

NGC 3576, the Statue of Liberty Nebula

Enjoy,

The third image uploaded today! NGC 4833, Caldwell 105

Hi all,

 

This image breaks a tradition in the latest images I have posted: it is not a Nebula!! NGC 4833 is a globular cluster that is considered to be one of the oldest globulars in our galaxy. It is considered to be older than M 5, itself about 13 billion years old!. You can find it at:

NGC 4833, Caldwell 105

Enjoy!

PS: the next image will be again a nebula… promised! even very probably a 1×2 mosaic…

 

Another image posted: NGC 6188

Hi All,

An image of NGC 6188 (together with its associated open cluster, NGC 6193) has been already uploaded. This narrowband image (only Ha and OIII, no SII this time) shows extraordinary detail in the “rim” area. This nebula is usually processed in the Hubble Color Palette (HCP) rather than in natural color, but I prefer this color palette and this is what you fill find at:

NGC 6188 and NGC 6193 (Caldwell 82)

Enjoy!

A special nebula: NGC 3324, the Gabriela Mistral Nebula

Hi all,

I have just uploaded a new image. This time, NGC 3324, the Gabriela Mistral Nebula (due to the resemblance of it to the face of the Chilean Nobel Prize Laureate), an emission nebula that is part of the Eta Carinae Nebula complex. It is a narrowband image that, as usual, has been processed as to reproduce the natural optical spectrum of the nebula. Remarkable in this image is that the OIII emission (teal-bluish in color) is quite strong in the “face” area, and it better shows the “face” of Gabriela Mistral than in regular RGB images.

You can find it at:

NGC 3324. The Gabriela Mistral nebula

Enjoy!
