Majestic Star Factory in Monoceros
The Rosette Nebula captured recently in Narrowband using a QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on the Takahashi 130 FSQ that we have the honor of testing for QHYCCD.

In this Hubble Palette version (SHO) the H-Alpha is mapped to green channel, SII is mapped to red channel and OIII is mapped to the blue channel.
Captured bin 2x2 over 3 nights in March 2021 for a total acquisition time of only 4.75 hours.

The dim constellation Monoceros, just east of Orion, hosts yet another majestic star factory. The Rosette Nebula, a vast wreath of gas and dust with a cluster of new stars near its center, is not associated with the Orion Molecular cloud but lies further along the Orion Arm of the Milky Way.
The Rosette has an apparent size similar to the Orion Nebula. But at a distance of 5,000 light years, it’s three times farther than the Orion Nebula, which means it’s intrinsically three times larger, spanning a diameter of about 115 light years.
