Edge-on Spiral Galaxy NGC 253 | jpeg, 54K |
|
This spiral galaxy is nearly 'edge-on'; the plane of the spiral arms is almost parallel to the line of sight, and it makes the galaxy's dust lanes be seen clearly. The distance between us and the galaxy is relatively close (about 8-10 million light years), and the apparent size of the galaxy is larger than the field of view of the CCD camera. （Image taken on 15th Nov. 1998. Compisite of 8 mins. exp. for BV bands and 5 mins. for I band.) Uploaded on 1999.1.6

Active Galaxy M77 | jpeg, 34K |
|
This spiral galaxy Messier 77 (aka NGC1068, ARP37) is about
47 million light years away from the Earth.
Though it is relatively distant galaxy, it can be seen with our 1m telescope,
because of its active galactic nucleus. （Image taken on 13th Sept. 1998. Compisite of 10 mins. exp. for BVR bands.) Uploaded on 1998.10.22

"Ring Nebula" M57 | jpeg, 39K |
|
This is a representative of Planetary Nebula,
The brightened gas emitted from a star(seen in the center of the ring).
This nebula is relatively bright, and you can watch it in our
public observation during summer. （Image taken on 20th Aug. 1998.Composite of 5 mins. exp. for BVR bands.) Uploaded on 1998.9.18

Black-Eye galaxy M64 | jpeg, 12K |
|
This spiral galaxy, located in Coma, has a distinct dark lane. It looks like an eye. The distance between the galaxy and us is approximately 16 million light years. （20th May 1998, 10mins. for BVR bands and composite)Uploaded on 1998.8.15

Globular Cluster M13 | jpeg, 58K |
|
This representative globular cluster, comprise of several hundred thousand of stars, is in Hercules. Though the distance between us and the object is large (22 thousand Lightyears), it is rather easy to view with eyepiece. So this object is frequently selected as the target of our public star watching. （14th July 1998, 2 mins. for R&G bands, 3mins. for B band and composite）Uploaded on 1998.7.19

Supernova SN1998bu in M96 | gif, 86K |
|
On 9th May (UT), a Supernova was discoverd in the galaxy M96 located in Leo and named 'SN 1996bu'. Since the distance between the galaxy and us is relatively short, this supernova could be seen with 1m telescope of Toyama Astronomical Observatory for about a week. (19th May. 1998, 5 min. exposure with Open filter.) | ||

M51, whirlpool galaxy | jpeg, 36K |

M51, a well-known starburst galaxy in Canes Venatici. which is 21 million light years away from the Earth. (3rd Apr. 1998, RGB composite of 5 min. exposure for each band.) | ||

M66, spiral galaxy | jpeg, 11K |

One of the spiral galaxies in Leo. 27 million lyrs. (28th Apr. 1998, RGB composite of 10 min. exposure for each band.) | ||

M104 | jpeg, 11K |
|
This spiral galaxy is well known as "sombrero galaxy". The distance between our Galaxy and it is about 46 millions lyrs. (28th Apr. 1998, RGB composite of 10 min. exposure for each band.) | ||
