The Wizard and the Heart nebulae

Yet another clear night with temperatures just under 20° made for some pleasurable viewing and imaging, and with the peak of the Perseids due shortly this was a good opportunity for some meteor spotting too, however they seemed to be in short supply! Jupiter and Saturn looked amazing though! Due to the almost full moon I used the narrowband filter for imaging, turning my attention to the Wizard and Heart nebulae and managed 2 hours total exposure on the Wizard nebula and just over one hour on the Heart nebula.

NGC 7380 (The Wizard nebula) – 2 hours total exposure imaged in narrowband using an Optolong L-eNhance filter. This lovely cluster of stars surrounded by a striking red emission nebula is located in Cepheus and is some 8,500 ly away.

IC1805 (The Heart nebula) – 1 hour and 6 minutes total exposure with an Optolong L-eNhance filter. Due to the huge size of this object (over 2° of sky) I could only get a small part of it in the FOV. At least this makes it look respectable though, as rather than a heart, I think the whole thing resembles another part of the anatomy! I guess this target is best done using an SLR, so I might give that a go next time. The Heart Nebula is some 7,500 ly away and is located in Cassiopeia. There are some lovely dark dust lanes that come out in this image.

These data were captured in NINA, stacked in DSS and edited in Adobe CS2. Equipment used was an Atik 320e OSC camera filtered with an Optolong L-eNhance narrowband filter, fitted to an Altair 60EDF doublet refractor with a 0.8 x FR on an iOptron CEM26 mount, guided with PHD2 using an SVBony SV165 guide scope with a QHY5-L-II-M camera.
