NGC 2024 Flame Nebula RGB

By |2019-12-05T16:10:37+00:005 December 2019|Categories: Nebula, News, NGC Winter|

Wasn’t expecting it to be clear so this is a bonus. Only managed 5 of each colour though so quite noisy and Alnitak overpowers eveything.

IC410 Tadpoles in Hydrogen Alpha

The two tadpoles are about 10 light years long and places of star formation.

Fish head nebula (IC1795)

This is a bit of a weird looking one! Stars to the left aren’t good shapes – probably combination of optical alignment, focus and collimation. Stars are over-processed too – should have been so much better.

Could only fit part in the FOV

Part of the North America nebula – the Central America part – seems to be known as the Cygnus Wall. Can only fit a small part of this object in my FOV.

Wizard Nebula HOO NGC 7380

After doing HOYS-CAPS data on a very murky, moonlit night, decided to try narrowband on this.

Cave Nebula Sh2-155 / Caldwell 9

By |2019-09-21T16:29:23+00:009 September 2019|Categories: Caldwell, Narrowband, Nebula, News, NGC Summer|

Sh2-155 is a diffuse nebula in the constellation Cepheus, within a larger nebula complex containing emission, reflection, and dark nebulosity. It is widely known as the Cave Nebula. Sh2 designation because it’s part of the Sharpless Catalog (1959) of 312 HII regions. About 2400 light years from Earth and a stellar nursery.

Narrowband filters really do cut through the murky, light polluted skies of Edinburgh so well. Obviously false colour, has to be for narrowband, but can’t decide which is the best so two different tone mappings: SII Ha OIII -> RGB and Ha OIII SII

Iris Nebula NGC 7023 / Caldwell 4

By |2019-08-29T12:59:19+00:0029 August 2019|Categories: Caldwell, Nebula, News, NGC Summer|

Been meaning to do this one for ages. Not easy because the background gas and dust can be easily lost in the light pollution and noise.

“The Iris Nebula, also known as NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +6.8 star, SAO 19158.”

Cocoon nebula IC5146 / Caldwell 19 RGB

By |2019-08-29T12:55:55+00:0028 August 2019|Categories: Caldwell, Nebula, News, NGC Summer|

“IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a reflection/emission nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula.”
