The Chip Thief.. aka The Seagull Nebula IC2177

A popular target this time of year, the nebula IC2177 soars like a huge magenta bird just south of the celestial equator on the boarder between the constellations of Canis Major and Monoceros. Like The Orion nebula, to me at least, this object never seems to look that good in narrowband ...so I used narrow band emission line data to augment a natural true colour SIIHaOIIIRGB image...quite happy with the result in the end.

I wanted to frame it so it really looked like it was soaring like a bird.

As is the case all the time these days, the data collection went without a hitch with perfect guiding, as good as +/- 0.15 arc sec for extended periods and not one sub chucked

The Seagull Nebula (click on image to enlarge)

If you want to soar around a larger version go HERE

For the old fashioned purists..HERE is the full size full res Ha only version, with only DDP and log stretch applied, nothing else

Here is an Annotated Version (courtesy of the venerable Sakib Rasool - he has a thing for making things North up ) to identify all the good bits.

Cheers

Mike

Very striking. I like it. Lovely star colours as well. Quite a lovely field. Good choice of target as it suits the FSQ very well.

You should be very happy with that result. It's beautiful. I would like to know how you go about stretching the data? The stars are very tight and controlled.

So often it seems like if I stretch the image to the point I like the nebula or main object, the stars come out bloated and larger than I want. I can only reduce star size so much before adverse artifacts show up.

Awesome. I had to do a 2x3 mosaic to get similar FoV. Also jealous of your guiding accuracy

Aaargh! Another one! .. and it's lovely too! You guys (incl. Troy) are killing me!

it's a beautiful image Mike - I'm enjoying the - traditional? treatment and colours - your star colours are spot on, and the composition is terrific!

Thought I had all the data I needed on this thing (22hrs) after two months and two panels but to balance the composition it needs three more panels (sigh), loving that new widefield combo of yours.

Thanks Greg, yeah trying to chose targets to make the most of the chip and corrected field...there are so many cool ones and not enough clear nights

Thanks Joel Basically...I median combine dithered subs, apply DDP then a log stretch, then adjust the curve on the mono data, all using Astroart6. I am carful not to over stretch the stars and I can usually achieve this by using several adjustment points along the curve, adjusting the nebulosity without affecting the stars too much Then when I take it into PS I protect the stars if necessary.

Cheers Troy, yeah a 4deg X 4deg FOV should allow me to avoid dastardly mosaics for a while longer now

Ha ha cheers Andy, yes the massive FOV with this outfit is pretty darn useful I'm slowly losing my overexcitedness ..it's just that I haven't been able to image these sort'a fields with that cool sharp look since the mid 80's when I had a Pentax 6X7 and 300mm Lens

Gorgeous and compelling. I spent ages just enjoying the variations in texture and colour in the starry background. One thinks of a seaside that varies from polished wet gravel to finest sand to interesting sea-shells large and small. And then there is the nebula! Lovely work.

Best,
Mike

Thanks a lot Ray...I'm really enjoying these wide sharp vistas...but heck, your bloody latest top notch galaxy shot has made me feel like switching over to the H694-AG12 (takes just a couple'a minutes) for another one myself, ...after I have completed the latest wide shot I have under construction

Glad you enjoyed the view Mike, it's great seeing so much in one frame...I think all I need now is something like a nice 180mm F2.8 lens to complete the set

The FOV is awesome with this combo for sure.

Cheers Simmon, glad you think so, always kinda not quite sure when composing hybrid NB-RGB images...

I like this composition Mike. Lots of great detail to wander around in, especially with the Ha.
