How Fitting for Halloween……My latest image – NGC6960 – Witch’s Broom in Hubble Palette Narrowband

Commonly referred to as the Witch’s Broom or the Western Veil of the larger Veil Nebula, this lies approximately 1470 Light years away.

15x600S in 7nm HA
15x600S in 7nm SII
15x600S in 7nm OIII
25 Darks
25 Flats

The HA was also used as a Luminance Layer

My first image with the Skywatcher Quattro 8-CF F4

NGC7023 – Iris Nebula
The Iris Nebula, also NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158.[1] It shines at magnitude +6.8. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across

This is the very first time I have imaged this object, and it is the first object ot be imaged with my new Skywatcher Quattro 8-CF F4 telescope, I am extremely happy with the results

The image consists of the following:
Luminance: 19x300S
Red: 13x300S
Green: 13x300S
Blue: 13x300S

All frames have 25 darks and 25 flats applied also

My Observatory MkII

After deciding to move my equipment from the farm to home, to make my imaging tasks a bit easier, I decided I was going to design and build a roll-off roof oberservatory this time, this will allow me to possibly automate the roof later on, so for this I first had to dig down by 3ft in order to build the base for my Pier, inside this 3ft was also re-inforced bar going out to different angles to the surrounding earth and also straight down into the ground below the 3ft hole, it was then poured with concrete and the template for the steel pier bolts placed resulting in the following:

1434124682

The base was an 8ft x 8ft base, but my observatory design was to be an 8ft x 6ft because I did not plan on being present in the observatory during imaging so I did not need that much space around the equipment, as you can see my garden slopes down quite a bit too.  The bricks around the outer edge were purely to allow me to pour concrete down the edges to get a smooth finish on the outside prior to be filling the whole base with concrete.

A few days later, the concrete arrived and was poured into the base resulting in the following image showing the concrete “Curing”

After the concrete had cured, I used a thin film of leveling compound on the observatory base just to give it a much cmoother floor and allow me to paint it with a nice clean dark grey concrete floor paint, and once dried I started constructing my observatory which resulted in the final build below:

1438026075

As you can see from the above image and the image below, I still had my Astro-Tech AT8RC which I have parted with in favour for an F4 Quattro Reflector which is now my primary imaging scope

I am extremely happy with the observatory, I am working through a design to allow the automation of the roof as well.  In total the construction of this obervatory took me no less than a few days to complete, I hope this inspires you folks out there contemplating building your own to get out there and do it!
