M78
This is a two pane mosaic taken with the data below to cover M78 and part of Barnards loop and then the other side of the mosaic included LDN1622 (the Bogeyman nebula) that was also enhanced by the mosaic from the larger focal length TMB.
The data involved in this image then is quite significant and from two very different focal lengths...... I have plans for more of this next year!! Data from 2017 with the dual Taks M: Mesu 200 T: Takahashi FSQ85 0.73x C: QSI683 and Moravian G2-8300 with Baader RGB filters, 3nm Ha Astrodon filters and Hutech IDAS. 70x300s RGB 30x1800s Ha 45x1200s Luminance Data from 2018 with the dual Taks M: Skywatcher EQ8 T: Takahashi FSQ85 0.73x C: QSI683 and Moravian G2-8300 with Baader RGB filters, 3nm Ha Astrodon filters and Hutech IDAS. 11x1800s Ha 72x900s Luminance 75x300s RGB Data from 2018 specifically in LDN1622 with the TMB M: Mesu 200 T: TMB 152/1200 C: QSI690 3nm Chroma Ha filters This is a TOTAL exposure now of 104.45 hours of data |
M78 is is the blue reflection nebula upper left of the frame, Barnards loop is the red area running through the centre of the frame and LDN1622 is bottom right.
The nebula Messier 78 (also known as M78 or NGC 2068) is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780. M78 is the brightest diffuse reflection nebula of a group of nebulae that include NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth. Barnard's Loop (Sh2-276) is an emission nebula in the constellation of Orion.The loop takes the form of a large arc centered approximately on the Orion Nebula. The stars within the Orion Nebula are believed to be responsible for ionizing the loop. Recent estimates place it at a distance of between 518 light years and 1434 light years giving it dimensions of either about 100 or 300 light years across respectively. It is thought to have originated in a supernova explosion about 2 million years ago, which may have also created several known runaway stars 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. |
M78 and some of Barnards loop

This is another image taken with the dual rig.
Details M: Mesu 200 T: Takahashi FSQ85 0.73x C: QSI683 and Moravian G2-8300 with Baader RGB filters, 3nm Ha Astrodon filters and Hutech IDAS. 70x300s RGB 30x1800s Ha 45x1200s Luminance Total exposure time 47 hours 30 mins. This has been blended as a simple RGB combination, then with the Ha data added into the red channel. The luminance layer was created using the luminance data and some Ha data added. |
You can see here that M78 is located very close the the Great Orion nebula and you can see where it is in relation to the famous constellation that is so easily recognisable.
