Trapezium - drawing or map

[The Mekon (John Briggs)]

Where can I find a detailed drawing or map of the theta orion area? What I would like is one that shows the stars in a one degree field centred on the trapezium, with magnitudes shown.
I have the one in Burnhams, which shows the E,F, G&H stars, but I would like to see one that goes a bit wider.

many thanks for any suggestions

John, how deep are you interested in going? My copy of CdC has about 950 names for objects mag 15.9 or brighter within a degree of 41 Ori A. There are duplicate designations - about 480 come from UCAC4 and 400 from GCVS.

Andrew,

Is that Carte du Ciel you are referring to? I checked this out recently. May I ask is it really a free download, how big is the file and will it show the charts? I am a bit reluctant to do big downloads on my net connection. I only need the area down to about mag 14.5 to determine just what I can pick up in this area.

many thanks
John

John, yes CdC == Cartes du Ciel == Skycharts. It's free and how big it is depends on what catalogs you add to it. The base Win32 download is about 30MB. The supplied DSO images add 57MB and the extra stars 52MB. I also have compiled copies of NOMAD (~210GB but compresses to about 97GB), UCAC3 (~4GB) and UCAC4 (~6GB). I could cut you a couple of DVDs of the version of CdC I'm running, the extra DSOs and stars, and compiled UCAC4.
The jpg and zipped CSV are roughly the area you asked about, restricted to mag 14.4 (Extended Hiparchos, Tycho-2, GCVS, and SAO catalogs).
