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.

M92 RGB

Because sky conditions were very poor I went back to globulars as nebulosity can easily disappear in LP and fog. APP got rid of the massive gradients and LP quite well I think.

IC410 Tadpoles in Hydrogen Alpha

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

Fish head nebula (IC1795)

By |2019-12-05T16:01:34+00:005 December 2019|Categories: Nebula, News, NGC Autumn|

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.

Cygnus Wall NGC 700 (Caldwell 20)

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.

Done this one quite few times now but this is the first time processing with Astro Pixel Processor. Good for gradients and light pollution but a little slow.

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
