LDN1622 - the Bogeyman nebula

Picture
​Details.
M: Mesu 200
T: TMB 152/1200 
C: QSI690  3nm Chroma Ha filters

​5x1800s in each pane - Totalling 15 hours of total exposure time.


LDN 1622 is located near the galaxy plane in the constellation of Orion. It is close to Barnards loop, a huge cloud that surrounds the emission nebulas found in the Belt and Sword of Orion.

LDN 1622 is thought to be much closer to the more famous Orion Nebula, perhaps only 500 light years away.

This is a big 6 pane mosaic in order to get most of the nebula into the frame. 

This image uses A LOT less data than I would normally like, but it's something that I've wanted to image for ages so I hope to return to this next year when I can catch it earlier in the year!

The Pre-Main-sequence star in the Bogeyman nebula

Highlighted here is Parsamian 3 (HBC515, HD288313) - It is a pre-main-sequence star that has been studied extensively. The information can be found below in a pdf.
​
What is a Pre-main-sequence star?

Pre-main-sequence (PMS) stars are young stellar objects that have not yet begun to burn their hydrogen core, instead fuelled by gravitational contraction and deuterium fusion. For such stars to be visible they must have shed 'most' of their birthing cocoon material of dust and gases gathered earlier in their life as a protostar. Once this envelope has been blown away, then the star is optically visible. It begins to contract and its internal temperature rises until it begins it;s hydrogen burning........ This is the Pre-main-sequence.
