M104 – The sombrero Galaxy

M104 – Astro-Physics 127.mm f/8, 0,78x reducer, Nikon D750a, 40x180s, ISO100, PixInsight, BlurXterminator, NoiseXterminator, ArcSinh Stretch, 2x drizzle

Since about 30 years ago, when an astronomy club colleague showed me M104 the sombrero galaxy in a 20×60 binocular it was one of my favourite deep sky objects.
A night after the great Aurora Display of 2024 I joined a friend who was imaging the Leo triplet, and had a go at M104 using the Starfire 127mm on the G-11 mount. We had a fun evening, saw some faint meteors, watched the milky way slowly rising.

M101 – the Pinwheel Galaxy

Messier 101, the Pinwheel galaxy, 50x180s, Nikon D750a, Astro-Physics 127mm f/8, 0,75x reducer, Losmandy G-11, PixInsight, NoiseXterminator, BlurXterminator, ArcSinH stretch

M101 is a slightly disturbed spiral galaxy we see face on, it is located in the constellation Ursa Major, the big bear. This is the first image I have taken since I updated the G-11 mount with the rectascension extension, which also allows separating the RA and DEC units for portability. I also switched out the original tripod for a Meade Field tripod, which is lighter and packs smaller.

Rosette Nebula

I chose the Rosette nebula again as my target of choice when I wanted to test if I can improve on the image quality when using the 0,7x reducer.

The Rosette nebula is a large and relatively bright emission nebula in the constellation Monoceros. Various parts of the nebula have separate NGC numbers and the embedded star cluster itself is NGC2244

This wider view was taken with the Takahashi FS-60CB and shows the surrounding area of the sky.

Later I discovered that the reducer only provides a 10% reduction in focal length, while introducing quite a bit of vignetting.
