I have been re-shooting some of the popular objects with the Rasa8 and the ASI1600 mono camera.

Here are a couple of images.

 

The iris is the most recent one. The Cave is a rework of old data and it's about 50% of the full frame. I added some Ha data that was framed very differently and so that crop is what I ended up with.

This time I will post the Astrobin links.

I hope you enjoy!

These are real nice images Andysea.  I like the NGC 7023 IFN and the Cave Nebula colors.  Great guiding and nice sharp stars...!  Great processing.

Very cool images Andy.

 

Is this new equipment for you? I was curious as to your exposure times with the RASA? The Cave image says your integration was 0.0 hours (the Iris has no integration time). I know the RASA is fast, but probably not that fast.

Jim, this is not a new setup for me I've had it for a while.  The Astrobin interface is a bit tedious so I entered the image details in the description.

Here is the run down:

 

Cave: 530x30s lum + 60x45s rgb + 60x120s Ha

All at gain 139 offset 50 temp -20c.

 

Iris: 630x30s Lum + 60x30 each RGB. Astronomik Lrgb filters.

All at gain 139 offset 50 temp -20c.

Very nice images, Andy!  Love the colors in the Cave Nebula.  You must be in a dark sky area, I can't seem to get the nebulosity you do.

Wow, it sure made a huge difference over my Bortle 5-6.

Oh yes I am sure that the dark skies help a lot. It makes processing a lot easier.
