Taken with the new larger scope in Spain with ASERO. Coma corrector spacing still not right so some star elongation, partially sorted in PS

Collinder 26 – the heart of the Heart Nebula

2022-10-11T14:40:27+00:0027 September 2022|Nebula, News, NGC Autumn, Open Cluster|

Ha view of this interesting star forming region at the heart of the Heart Nebula. Various designations for the open cluster including Melotte 15 and IC 1805. The emissions from the Heart Nebula are driven by radiation from the young stars in this cluster.

M42 CCD Rc

Was setup for an exoplanet transit but cloud got in the way, so took 4 frames M42 with the R-Cousins filter and CCD camera again. Not bad!

NGC 7142 and NGC 7129

2021-12-24T16:41:36+00:0017 December 2021|Nebula, News, NGC Summer, Open Cluster|

Strong Moonlight interfering but an unexpected clear night so all good. Nice sharp open cluster and 7129 is a HOYS object I image a lot.

Below is a less processed image showing the Moon gradients. By processing them out you definitely lose details.

Pillars of creation

2021-12-08T19:11:22+00:008 December 2021|Nebula, News|

Not the famous ones in the Eagle Nebula, but still areas where stars are being created. These cold molecular pillars, generically known as elephant trunks, are areas of cold, dense gas, often associated with star formation. Research suggests they rotate, over periods of a few million years, as a semi-rigid structure, causing them to twist and change shape over time.

I thought I’d gather some closeups of them together from my recent images. The Pelican and Elephant Trunk nebulae are areas that I study along with the Hunting Outbursting Young Stars (HOYS) Project.

NGC 7822 narrowband

2021-12-08T09:22:50+00:006 December 2021|Nebula, News, NGC Autumn|

Homebrew false colour palette to help bring out the different regions. Interesting “pillars of creation” shown in the inset. Not the famous ones in the Eagle Nebula, but this object, along with the Elephant trunk nebula, also have similar features. A young star forming region in Cepheus, contains Sh2-171 and cluster Berkley 59.
It contains one of the hottest known local stars (marked) BD+66°1673, a O5V eclipsing binary. This star illuminates much of this nebula and forms the “pillars”. It is 45,000K and 100,000 time more luminous than the Sun.

Looking for more obscure objects again. This is a young star forming region, contains masers too. Very close to the Bubble Nebula but just across the constellation boundary in Cepheus. In the Perseus arm of the Milky Way.

2021-12-08T09:23:22+00:0016 November 2021|Dark nebula, Nebula, News, NGC Autumn, Open Cluster|

An obscure one in Perseus. The larger is open cluster inside an emission nebula NGC 1624, also known as emission nebula Sh2-212, the smaller Sh2-211. Now known as the Tribble Nebulae after “Star Trek: The Trouble with Tribbles”. The dark patch top right is the dark nebula Barnard 20.
