Objects Session Notes ++
- 3.8 hour session - main aim was to record follow up images of comet 73/P SW-3 and recent supernova - 2006bp, 2006bt. Opportunity was taken to acquire images of M81 & IC 2574, with telescope/camera operating at their extreme northern declination range. - More Notes -

| CGCG 108-13 with SN 2006bt (Serpens Caput) 2006bt was discovered 2006/04/26.48 by Lick Observatory Supernova Search (Rochester Supernova site | Discovery Image | Reference Image) Image below (2006-05-03.976) was taken 7.5 days after discovery. Estimated magnitude of 2006bt is +17.0 (C filter). |

| UGC 5434 (Serpens Caput) A mag +18 supernova (2006bx) has reportedly been discovered in UGC 5434 on 2006/05/01.26 by Lick Observatory Supernova Search (Rochester Supernova site | Discovery Image | Reference Image) Image below was taken 2.5 days after discovery. No indication of an object at the reported position of the supernova. This is probably due to the mag +18 supernova being too faint to be picked up in the exposure - the limiting magnitude of the CCD image is approxmately +16.5 (C Filter) |

| Hubble Deep Field (Ursa
Major) In December 1995 the Hubble Space Telescope assembled an image of a small 2x2' region in Ursa Major over the course of 10 consecutive days. Known as the Hubble Deep Field (HDF), it was was the deepest ever field taken at that time and showed tens of thousands of galaxies out to a distance of 13 billion light years. Repeating a previous ambitious attempt, I tried to image the same area, under slightly better conditions that last summer's attempt (2005-06-10). With an image of 16 minute (total) exposure, objects as faint as +18 to +19 are visible, including at least 2 of the brightest galaxy objects in HDF |
