Object of the Week, March 2, 2025 - NGC 2750 = UGC 4769 = VV 541
R.A.: 09 05 48 Dec.: +25 26 15
Size: 2.2 'x 1.9', Magnitude: 11.9
Cancer
NGC 2750 is an intermediate spiral, SABc, according to its Hubble and de Vaucouleurs galaxy morphological classification, and is about 123 million light years away, in Cancer. It transits about an hour before midnight at this time of the year, so it is well placed for observing in March. NGC 2750 was discovered by John Herschel on March 11, 1785.
According to this informative article (https://images.mantrapskies.com/catalog/NGC/NGC2750/index.htm), written by the late astrophotographer, Rick Johnson (RIP Rick), “… It's odd shape and two heavy arms have resulted in it being listed as two or three different galaxies…” Rather than just quoting other factoids from this article I’ll just leave it to readers to follow up on their own. It is a fascinating article and has some very nice photos, including a labeled photo. Here is one of Rick’s wonderful photos…

Here is a screenshot of the area from Megastar…
5666
The circle is 30 arcminutes in diameter, so in a wide field eyepiece you should also see 3 other galaxies, as follows;
NGC 2753, mag 15.4, 18.9 arcminutes away at PA 107
UGC 4774, mag 15.0, 11.1arcminutes away at PA 37
UGC 4764, mag 14.9, 8.3 arcminutes away at PA 324
In photos, NGC 2750 is clearly triangular in shape, but in my 25” f/5 dob it was just slightly out-of-round and uniformly illuminated, with a bright stellar core.
As always, give it a go and let us know.
