The Dolphin Nebula

[gregbradley]

I have been intrigued by this object since I first saw it a few years ago.
Since then its been a popular target whereas before it was rare.

My second imaging of this object.

AstroPhysics Riccardi Honders astrograph (305mm F3.8).
PME mount, QHY 600M camera, MOAG guiding with a ZWO guide camera.

Taken at my home observatory in Sussex Inlet over several nights. Good seeing as is typical here (only occassionally is seeing average).

6 hours and 10 mins O111 Ha RGB.

the original high res version is very close up! lots of nice stars to complement the nebula detail. Thumbs up!

Thanks Paul.

It took me several goes at processing to get a result that I liked.

If you are referring to your 2016 effort with the 694 chip, yep, this latest version is much better

It's a must do object for sure.

Yes that's the one. When I did that earlier one it was already really too low in the sky.

Your FSQ widefield version is a standout for me. I'll image it again another time with the 110GTX.

It's a pretty wild object with surprisingly sharp boundaries.

Excellent work, Greg! Yes, a most intriguing object. I've got to put it on my list!

Thanks Peter.

It's quite bright in O111 but there are a couple of really bright stars that need to be kept in check.

It's a very hard nebula to process!

Beautiful results in the end, Greg

really beautiful take on a pretty tough target. That superb scope of yours just sucks up those rare photons I bet. I had trouble getting a useable image at f7.2 from several nights' observations

Thanks Franco.

The super sensitive QHY600m plus the F3.8 12 inch AP scope do mean I get a lot quickly. This can be vital when I am away at my dark site where time and weather are limited.
