Medusa Nebula

This is a pretty faint nebula, an 8800 year-old planetary nebula, situated a little northeast of Procyon.

It’s surface brightness is very low. During the imaging session, the nebula was almost invisible on the monitor. I’m really surprised it came out so good. Obviously this is not a narrowband image, it’s created using a One Shot Color camera.

The Medusa Nebula in Gemini, NGC 2395 153x120seconds Gain 0, a bit more then 5 hours. The sky did not reach SQM 20 so it was not so good.

Really need to learn how to use this camera and process the images, very different again from B/W and DSLR. The gain was set to “0” (“Maximum dynamic range”). Using the 120mm Esprit @ F7 native focal length of 883mm. As a first impression also the camera takes a lot longer to cool down compared to the ASI183MM and the files are pretty large at 50 Mb.

Venus & Mercury before sunset

With the crescent Moon as a reference, this was the moment to find Venus and Mercury back, in plain daylight, just before they would both hide behind the roofs & trees. Actually this is my first ever Mercury picture (widefield excluding). Both pictures with the Esprit 120 & ASI290MM.
