More works-in-progress

Since we're talking about works in progress, here are snippets from one.

I started imaging M8 and M20 in narrowband last week. Unfortunately, I also found out that I have a very small window of opportunity to shoot these magnificent objects before they duck behind a tree (2 hours max).

I have a feeling that this will be a multi-year project, unless I manage to pull an all-nighter or two at a site with an open southern horizon.

They both fit in the FOV of my STL-6303 on a Takahashi FSQ-106, but given the size of the full image I cropped out the objects of interest.

Here is M8, around 60% of actual size, cropped from the full frame.

Exposures (H-alpha only):
2 x 20 minutes
3 x 15 minutes

This object is so bright I may have fried the core in the 20-minute shots. Even the 15-minute shots were a bit bright/bloomed in the core.

Enjoy,
Eric

And here's M20. Cut from the same frame, so same imaging specs (though I believe this is full size). I actually have 30 minutes' worth of both S-II and O-III data, but the moon was pretty close when I shot these, so I don't know if they're even worth salvaging.

Nice shot Eric. How do you find your STL6303 overall?

Is that a class 1 or 2 chip?
