Rosette core & The Carnival of Animals - a bit of fun!

Recommended Posts

This image comprises recent Ha data from e-Eye from the TEC140/QSI690 Steve and I operate and SII, Ha and OIII data from my home observatory in Totnes acquired in 2018 using my WO 132FLT/QSI683 at 1.47"/px, here.

Steve and I have been imaging the Rosette core at 0.75"/px early evening as the moon has been rising before switching to other targets mid-evening. We will not be able to collect the SII and OIII this season so I processed the 28 x 1200s of Ha and re-aligned my older image to provide the 'colour' for the higher resolution Ha data: it is effectively like imaging bin 1 for the Ha and bin 2 for the SII and OIII.

After a crop to take care of the mis-aligmnent and some additional NR due to the resampling, a few enhancements, et voila!

The 'Carnival of Animals' reference is of course the resemblance of the dark dust to a troop of fantastical animals and Saint-Saens humorous musical suite. . . which animals, well your guess is as good as mine.

CS!  (minimal chance in the UK at the moment though . . . )

Ha data: Barry Wilson & Steve Milne.
Balance of NB data: Barry Wilson

(For those with an interest in the 'dark side', I am continuing to add topics to the tutorials on my SmugMug site: Calibration & Assembly, Basic LRGB workflow (in 5 parts), Boosting star colour, Starless NB technique, Deconvolution, Mure DeNoise, Introduction to enhancements . . . more to follow on masks, mosaics, NR, star reduction.)

Gorgeous, rich, and so much detail. Marvelous stuff as always Barry!

It was fun spotting all the animals! ? My fav has always been the 'Leeping Leopard'. Or is it a 'Crouching Cheetah'? ?

Another exquisitely detailed image. At 0.75 arcsec/pixel, do you also get a frequent stable atmosphere at e-Eye, as well as the clear skies? 

Thanks for the heads up on the LRGB tutorials, something for me to study in earnest, while I wait for the clouds to move on.
