The IC1805 Heart Nebula in Hydrogen-Alpha (Two-Pane Mosaic at 3nm)

[Gib007]

Here it is - three nights this weekend of a number of hours each of imaging the IC1805 Heart Nebula in Hydrogen-Alpha using my new Astrodon 3nm filter:

This is a two-pane mosaic captured with my Borg 77EDII refractor. It comprises 35 exposures in total, each exposure being 15 minutes long. I captured 30 flats per night out and overall 200 bias. No darks were used as this Sony ICX694 CCD sensor is wonderful at -10°C. Now just need to wait for the Moon to go away so I can gather Oxygen-III data and produce the bicolour palette image I'm after!

That's really lovely. Loads of detail coming through.

Very nice indeed, but is it maybe slightly bright in places that might be hiding some of the detail?

Very deep with nothing over exposed. Good stuff.
