Hello all! A new, wide field image of NGC 7293 (The Helix Nebula) has been uploaded. It is, like others that have been uploaded recently, a wide field image enhanced by blending in it a higher resolution image taken with the 20″ CDK. This image (like the higher resolution one) has been taken in narrowband, […]

Hi all, As I said in my previous post, I have uploaded a 1×2 mosaic, wide field, of the M16-M17 emission area (it also contains M18, an open cluster). This image has been processed using more than 43 hours of exposure (not including the hours of processing…). You will find two versions, the lower resolution […]

Hi all, I have uploaded two versions of M17, the Omega Nebula. The first version was taken with a 17inch telescope, and shows more detail. The second image is a wide field image of this nebula, and its core has been enhanced with the previous higher resolution image. This wide field image is the second […]

Hi all, A new, wider view of Messier 16, The Eagle Nebula, has been added to the web site. It is an image taken in narrowband and enriched by blending the core region with a previous higher resolution image taken with the 20″. This image is part of a series of wide field images blended […]

Hi all! A new image has been uploaded to the web site. This time, we start a new chapter as, for some time, we will be imaging with a wonderful TOA refractor 130mm f/5.7. The first region to be imaged and processed has been the Messier 8 region. This image spans nearly 3×3 degrees and […]

Hi all,   Another galaxy, this time NGC 521, a peculiar LLAGN (Low Luminosity Active Galaxy Nucleus), taken with the Schulman Telescope. You can find it at: NGC 521 Enjoy! Josep

Hi all, The activity has been recovered, after a three month period (we moved to a new location not far away from Philadelphia). A Planetary Nebula has been added to the web site. This time it is the tiny Shapley-1, a Nebula about which there is still some debate around its structure and distance. The […]

Hi all,   A new image has been uploaded. This time, it’s a galaxy, M104, the “Sombrero” galaxy. This nearly edge-on galaxy has the most massive black hole detected in galaxies at a distance of 30 million light years or less. It harbors a 1 billion solar masses black hole in its center. The image […]

Hi all,   After a brief period of a certain calm, a new object has been uploaded. This time, it is the Rosette Nebula (a fragment of it). It is a 2×1 mosaic taken in narrowband with the CDK 20″. This mosaic has been quite difficult to assemble as the stars in the “seam” region […]

Hi all,   This time, a pair of colliding galaxies are in the recently uploaded image. The Antennae Galaxies, NGC 4038 and NGC 4039 have been imaged. These galaxies outline what our galaxy, together with the Andromeda Galaxy, M31, will resemble when they collide in just a few billion years… It will be nice to see, […]
