NGC 1672 is a barred spiral galaxy located in the constellation Dorado. It was originally thought to be a member of the Dorado Group, however, this membership was later rejected.
NGC 1672 has a large bar which is estimated to measure around 20 kpc. It has very strong radio emissions emanating from its nucleus, bar, and the inner portion of the spiral arm region. The nucleus is Seyfert type 2 and is engulfed by a starburst region. The strongest polarized emissions come from the northeastern region which is upstream from its dust lanes. Magnetic field lines are at large angles with respect to the bar and turn smoothly to the center.

It was taken with a 36.8 cm F9 Ritchey Chretien telescope using a SBIG STXL16200 CCD camera. The exposure is a LHaRGB image with about 9 hours total imaging time.

Here is an image of Andromeda Clouds in HaRGB, with 23 hours of total exposure.
Captured during 6 nights of New Moon from Pioz, Guadalajara, Spain.

It is the biggest project I have done since I started doing astrophotography and it is an honor for me to be one of the few astrophotographers who have photographed these strange clouds in color.

Thor’s Helmet (NGC 2539, Sh2-298, Gum 4) is an emission nebula in Canis Major. The powerful Wolf-Rayet star WR7 near the centre of the nebula is causing the gases to glow. That star is thought to be in a brief pre-supernova stage, and could explode in the cosmically-not-too-distant future. This object is thought to be similar to the Bubble Nebula, but the energy from WR7 has blown the gas in Thor’s Helmet into more complex shapes.  Thor’s Helmet also contains much more oxygen structures than the Bubble Nebula. Oxygen gives the teal-coloured structure; hydrogen provides the reds. This nebula contains hundreds of solar masses of ionized gases (the gases that are glowing), along with hundreds of thousands of solar masses of unionized material. The age of the nebula is uncertain, with estimates ranging from 78,500 to 236,000.

This data used to create this image was acquired from Yass, New South Wales, Australia by my friend, expert astrophotographer Martin Pugh. Thank you Martin!

In this capture you can find the emission nebula (M42), a combination of emission and reflection nebula (IC434) and the reflection nebula (M78). Other objects can be found in addition to the three main actors in the photograph. Down under the capture details I named all objects in the field I am familiar with.

This picture shows emission nebula (M42), a combination of emission and reflection nebula (ic434) and a pure reflection nebula (M 78).
