Hi all, Another emission nebula has been uploaded. This time, Gum 29 (RCW 49) takes the stage. This nebula is a star forming region having given birth to the young and compact open cluster Westerlund 2, which contains a double star with two of the most massive stars known (82 and 83 solar masses). …

Another image uploaded!
Hi all, The second, (and last) image for today, has been uploaded. This time, it is an emission nebula (as it is quite common here…), RCW 75, also catalogued as Gum 48a. It is an extremely balanced and beautiful nebula (according to my view, of course). You will find it at: RCW 75. GUM 48A …
A new mosaic has been uploaded
Hi all, After a long period without posting new images (I have kept on taking images, only my available time for processing has been lately very limited…), I am glad to share a new image. This time, it is a mosaic (1×2) involving the Gabriela Mistral Nebula (NGC 3324) and its Eastern region (that I …
A new image has been uploaded
Hi all, A new image has been uploaded. This time, the globular cluster Messier 4 has been the chosen one. This HDR image of this rather small globular, was taken with 10 minute and 2 minute exposures. Please also note the high number of Blue Stragglers (more info in the web site), which for …
A new version of Messier 17 has been uploaded
Hi all, A new version (3rd, one in wide field and two in HiRes) of Messier 17 has been uploaded. I finally decided to capture this nebula with the usual (and very reliable) CDK 20″. The image was taken in narrowband (Halpha and OIII, mapped to natural color). You can find it at: Messier 17. …

IC 2220 surrounding bubbles. A confirmation
Hi all, I promised another post when these new bubbles had been confirmed. Three astrophotographers, Andrealuna Pizzetti, Tel Lekatsas and Christian Sasse have, independently, taken Ha pictures of this region, in order to try to confirm the existence of this bubbles. The integration of all their 19x600s images (see image here), taken with another 20″ …

An image of NGC 6302, the Bug Nebula, has been uploaded
Hi all, A new image has been uploaded. This time, a planetary nebula, NGC 6302, also called the Bug Nebula or the Butterfly nebula, has been the chosen object. This nebula presents several unique characteristics, such an extremely hot central white dwarf (250,000 ºC, one of the hottest recorded). The central star had not been …

A new, and special, image has been uploaded
Hi all, A new image has been uploaded. IC 2220 is an unusual reflection nebula, it is not blue but reddish orange. This is due to the fact that the nebular gas is reflecting the light of a Red Giant. But this image has an additional object around IC 2220, a bubble-like nebulosity that is …

An image of a galaxy has been uploaded
Hi all, This time, the image that has been uploaded depicts a galaxy. NGC 4945 is not that far away, 11 Mly and, therefore, it shows a great deal of detail. It definitely resembles NGC 253 due to its dust lanes and angle of vision from here. This galaxy has a very active nucleus (it …
An image of NGC 3293 has been uploaded
Hi all, A new image has been uploaded. This time, it is a very young open cluster (NGC 3293) surrounded by the nebulosity that originated it. Remarkable in this nebulosity is that the highly radiating stars in the cluster have not yet had enough time to carve/modify the nebulosity’s beautiful filamentary structure. You can find …
