NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister’s discovery in his catalogue and labelled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalogue (Sh2-142). This reasonably large nebula is located in Cepheus. It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter.

My first CCD attempt is the NGC7380 The wizard nebula in HA (for now) 🙂 It took 4 nights to gather the data, as I am still battling with meridian flips, ADU’s, Dark noise and the rest of the CCD parameters…
Enjoy!
