On May 1st, 2008, I managed to take this shot of Saturn, most likely the last of this season (which has been haunted by really bad seeing conditions) until the Ringed Planet emerges back from sunlight next winter. All data are in the picture.
Nowadays, high-resolution imaging of the solar system bodies is one of the few sectors of astronomy where amateurs can still make their significant contribution not only from a purely esthetical, but also from a scientific standpoint. However, this type of activity is very demanding and unforgiving of even the tiniest flaw, as every single bit of the instrumentation (from the optics to the imaging detector) is pushed to its limits. The Gladius is a telescope specifically optimized for high-res imaging. […]
From July 20th to August 9th, 2008, the 44th IAYC (International Astronomical Youth Camp) will take place in Sayda, Germany. I myself took part in these camps six times between 1991 and 1999, and in my opinion there is no better place where one can find such an ideal and balanced mix between science, friendship and amusement. The editions I participated in account for some of my nicest memories in my life. So, I am more than glad to put […]
On March 18th, 2008, the weather was once again clear, but the Foehn wind was sweeping Northern Italys flatland, as it has (too) often happened during this past winter. No surprise the seeing was really crappy. In spite of that, I managed to pull off the following image featuring Saturn roaming the heavens with five of its satellites! The satellites in the above picture are numbered as follows (verified with WinJupos): 1, Japetus; 2, Rhea; 3, Tethys; 4, Dione; 5, […]
by Emmanuele Sordini and Lorenzo Comolli The MagZero MZ-5m camera, the Italian flavor of the QHY5 CCD guider, has been around for quite a while, and has ever since been quite popular among amateur astronomers as a good bang for the buck. This camera has already been reviewed on bloomingstars.com: back then, we highlighted its streghts, such as its lightweight as ease of use (thanks to the built-in ST4 compatible interface; this time, we do a side-by-side comparison of sensitivity and […]
On Jan.24, 2008, another crystal-clear day had just started, when I spotted a waxing, almost-full Moon setting over the snow-covered slopes of the Mottarone, a well-known mountain (and ski resort) overhanging Stresa, renowned touristic resort on the western banks of Lago Maggiore. In no time, I was out on my balcony shooting a sequence of exposures which I later put together into the animated GIF “movie” shown above.
On Jan. 22, 2008, it was a crystal-clear night on the Po river flatland (Northern Italy), as the dry foehn wind was blowing steadily from the Alps’ leeward slopes, thus draining every single bit of humidity from the air. A full Moon disk was also shining bright high up in the sky. By no means, would I ever miss this terrific opportunity of shooting it… So, I grabbed my ‘scope (Vixen ED103SWT), slammed it on my G11 mount along with […]
One of the most-feared bugaboos for those who take up long-exposure digital imaging is getting nice round stars, as a result of good-quality autoguiding. To this end, there are several options available on the market: however, they are mostly dedicated devices (e.g. self-guiding cameras from Sbig, or Starlight Xpress’ SXV Guider ), or very powerful but pricey products (as is the case with the STV from Sbig), or even newcomers which still have to conquer their customer base (e.g. the […]
It’s been quite a while since my last post, let alone an astronomy-related one. However, this does not mean I don’t have anything to share! As a matter of fact, I do have a fair backlog of images to process and to post, but it’ll take a while as I’ve been very busy lately. Here’s a sample of my october 2007 deep-sky imaging session (NGC 253, a galaxy in Sculptor): which is actually my best result of that night… Click […]
