| Object: | M34 Star Cluster |
| Date: | October 5, 2002 |
| Equipment: | TeleVue 101 at F/5.4, HX916 CCD, G11 mount, ST-4 autoguider |
| Exposure: | RGB: R=12x2.5min, G=12x2.5min, B=12x2.5min |
| Processing: | Photoshop curves, no dark or flat frames applied |
| Comments: | Slight dew on the objective towards the end of the exposure caused the blue channel to bloat. The dew also ruined the flat-frames for this image, as it went undetected until the end of the exposure. |
| Description: | A
star cluster in Perseus constellation. Over 100 stars belong to this
cluster, with the brightest concentrated towards the center. M34 is 1,400
light years away from Earth and is estimated to be about 200 million years
old. It spans approximately 14 light years. It is believed that M34 is
part of a larger local group of star clusters that includes Pleiades.
There's a small galaxy hiding in this image,
designated UGC2175. Can you spot it? |
