Outline of the Talk

• The galactic anti-centre
• The newly explored 23h -gt 0h region of IPHAS
• Some other projects
• Comparison between IPHAS and SHS

3
The galactic anti-centre (5-6hrs RA)
Area surveyed by Anna Kovacevic in 2005. Found
30 extended nebulae candidates in 15x15 binned
data. Found 30 more possible compact nebulae
(incomplete survey).
4
The 23h-0h RA region
Area surveyed by Daniel Huggins (6th form
Nuffield student) and Rhys Morris in
2006. Found 40 extended nebula candidates in
15x15 binned data.

Other projects

• Looked for PN candidates in northern globular
  clusters.
• Looked for PN in Monoceros ring and other
  galactic streams.
• Variability studies by images subtraction.
• Variability studies by catalogue matching.
• CV search
• IPHAS/SHS overlap region
