NGC2244: the heart of the Rosette Nebula February 28, 2005 20:02:08 UT. This is only one frame of an AVI, but there is something strange: a bright object can be seen which does not appear on the other frames of the AVI, nor does it appear on any sky chart I consulted. I wonder what it is, maybe a piece of space junk ... Here are the collected opinions of several astronomers.
Simon Smith carried out (THANK YOU Simon !) a thorough investigation (see the opinions file) and issued a ZIP file with the 4 frames mentioned in the 'Opinions' file.

First time autoguiding, with the guiding 'Lidl' Skylux scope on top of the LX200 OTA. The autoguiding [K3CCDTools and LX200] worked nicely but I had made some errors: there was a hot pixel in the FFT where the guide star was and I assume that mixed up things. Also I had not mounted the guide camera correctly East/West so I need to work on this too. Alas the clouds came too soon so I had to quit before I could make the necessary adjustments. 7 autoguided exposures of 10 seconds.

Such galaxies are called polar ring galaxies, and NGC 2685 is an interesting and beautiful example. Because of its shape, it is also called the Helix Galaxy or the Pancake Galaxy.

NGC4298 and NGC4302 - Galaxies in Coma Berenices. March 11, 2007 22:55 - 23:07 UT. NGC4298 is a spiral galaxy and NGC4203 is an edge-on galaxy. Both galaxies are at an estimated distance of 60 million light years away.
This is my first attempt at this nice doublet. |
, type Sb, in Coma Berenices.<br>
RA 12 : 36.3 [h:m]; DEC +25 : 59 [deg:m]; Distance 31 million light years;<br>
Visual Brightness 9.6 [mag]; Apparent Dimension: 16 x 3 [arc min]<br>
The considerably bright, very large edge-on spiral NGC 4565 is another showpiece for amteurs, and often used in textbooks,<br>
as it is assumed that its view may resemble that of our own Milky Way.<br>
