Hubble's Variable Nebula - NGC 2261

Copyright Mark Hanson
HVN-LRGBsmall.jpg

Description by "Sakib Rasool"

"Like a cosmic flower, Hubble's Variable Nebula is a lovely reflection that appears to sprout from the bright star R Monocerotis. Otherwise catalogued as NGC 2261 by the astronomer John Louis Emil Dreyer in 1888 in his iconic New General Catalogue, this nebula was discovered in 1783 by William Herschel. It is also famous for the being the first deep sky object to have been photographed with the Hale Telescope at the Palomar Observatory in 1949 by none other than Edwin Hubble.

The popular name of this nebula arises from it being studied by Edwin Hubble in 1916 who noticed it changed in brightness. It is now known that its dramatic and quite quick changes in brightness and appearance are the result of opaque clouds of dust situated between the star and the nebula. The appearance of NGC 2261 has been observed to change on timescales of a few months if not a few days!

The reddish nebulosity visible to the north of NGC 2261 is an example of a Herbig Haro object, a type of jet ejected by a young star that glows by the energy generated by the gas colliding with its surrounding space. They were originally independently discovered by the astronomers George Herbig and Guillermo Haro. This Herbig Haro object is catalogued as HH 39 and more than a thousand are currently known. An analysis of the proper motion of the knots in HH 39 show that it is moving away from R Monocerotis and NGC 2261."

Thank you, Mark I like both versions of your image. Am I right to suppose that the red background in one of the images is scattered Hα?

Starting the galaxy season - NGC 2903:

The spiral galaxy NGC 2903 in the constellation Leo has been my first target in the 2019 galaxy season. Imaged with a 10inch Newtonian reflector and APS-C sized DSLR, right from my garden.

Clavius and Blancanus

Post by Luc CATHALA » Tue Mar 05, 2019 8:08 am

Hello
I submit you this Clavius and Blancanus picture.
Very little time in a life the sky allows in the Rhône valley in France to exploit almost fully the capabilities of large telescopes like my newton 24" that I built. It lasted 20 minutes on the night of February 15. I was able to image some craters like them in high resolution. The focal length used is 10920 mm (barlow 4), red filter 610, camera QHY5-III 178M.
Clear skies.

NGC 3718 - twisted galaxy in Ursa Major:

Used my 10inch Newtonian reflector and DSLR to capture that lovely galaxy which interacted in the past with its neighbour NGC 3729 to get that specific shape. Also of interest the far distant galaxy group south of NGC 3718 called Hickson 56.

Hi my name is Josef and I'm an 18 year old photographer from Cornwall.
I thought you might like this shot that I took at about 4am this morning!
