Notes

Melotte 15 - the heart of the Heart Nebula in Cassiopeia. 2h27m of Hydrogen Alpha at F12 (equivalent of about 40mins in the F4.5 Newtonian). It needs a lot more time and better skies to have the resolution I think it can achieve but I think it’s worth pursuing. The Classical Cassegrain 1836mm F12 + Player One Uranus M uncooled mono camera with 2.9 micron pixels gives an image resolution of 0.33 arc secs per pixel.
