Last night was the last night of clear weather for a week or so for us, so, despite the full moon, we popped the Dwarves up on the roof.

First up let's look at what I got the #DwarfII to do. I thought I'd revisit my old favourite, #C63 the #HelixNebula . What I got surprised me greatly.

Here is the same scene - about a fortnight apart - one shot on the #Dwarf3 and the other on the DwarfII. In both cases there is about 7 hours of exposure, at gain 80, and both are using a dualband #OIII / #HII filter.

Both were post processed in the #StellarStudio and finished in #Snapseed .

I am utterly amazed at just how good the Dwarf2 stands up. No, it is not as good as the Dwarf3, but it is still a solid image, and one I am very pleased with.
