    Default Hunting Caldwell List Galaxies with Binoculars: Spring



    Hello friends of binoculars and small scopes,

    this is a suggestion what to hunt in spring besides the Messiers.
    Parentheses indicate my last observation with binoculars.

    NGC 2403 - Caldwell 7: Very bright 8.9mag and large 21.9'x12.3' galaxy in Camelopardalis, with 8M light years actually not so much far away. In the same field of view with 51 Camelopardalis. Favourite target to monitor for supernovas with scopes. (15x85, March 2nd)

    NGC 4449 - Caldwell 21: The Box Galaxy in Canes Venatici, one of the brightest (9.4mag) galaxies with star bursts. Navigate to Beta CVn, fix the small NGC 4490 to its right, move about 2 fields of view up. (15x85, March 2nd)

    NGC 5005 - Caldwell 29 in Canes Venatici: Go to Alpha CVn (Cor Caroli), and follow a sparse cascade of stars to its lower left. The small C29 is nicely aligned at left. (25x100, April 3rd)

    NGC 4631 - Caldwell 32: The Whale Galaxy in Canes Venatici. Go to the visual asterism of Upgren1, and watch for a nearly vertical pair of bright stars below. Move to your left, and here is a large (15.5'x2.7) and bright (9mag) streak of light. (25x100, April 3rd)

    NGC 4565 - Caldwell 38: The Needle Galaxy in Coma Berenices, one of the best edge-on galaxies for binoculars and small scopes. Go to the left edge of the large open cluster Melotte 111. Move 1 field of view to the left, and here is the needle. (25x100, April 3rd)

    NGC 4559 - Caldwell 36: challenging galaxy for binoculars in Coma Berenices. Move slowly north of NGC 4565. (25x100, May 14th, 2005, therefore on my list for this season.)

    Here is one added "unlisted" galaxy, however highly interesting because of the variable brightness of its core:

    NGC 4051: Seyfert Type 1 galaxy with active core (suspect black hole): 10.2mag or brighter due to the variability, 5.5'x4.6'. Fix first Chi UMa, and go then to the right low to fix the wide (65") double 65 UMa. Move 2-3 fields of view lower to find the asterism around 67 UMa. Move back 1 field of view up to find a string of 4-5 stars. Aligned with the string is the galaxy NGC 4051.

    It would be great to find someone here around, who would be ready to monitor the bightness fluctuations of this galaxy.

    Wishing you much fun with these Caldwells, and with that one added

    More fun with binoculars (and telescopes). The Caldwell list contains many bright and interesting objects. There is always something new and interesting up there to pursue when the sky is clear, that is for certain. Thanks as always JG.
