Eta Carinae Nebula (Carina Nebula) imaged with a 4 in refractor at 390 mm focal length, an ASI 533MC cooled astronomy camera, dual band H-alpha and O-III filter, with an ASI 174MM guide camera. I am still testing the DIY focal reducer I’ve made using the objective lens of a Celestron Travel Scope 70.
