M51 2X300sec per colour

Just a quick image as I was trying to set up my new SA200.
Without much success!!

Horsehead Nebular – Last night 150 sec X 3 per colour

AAVSO Award!

Time flies when you are busy!!

Quick Monochrome image of the Triangulum Pinwheel -PGC 5818 in V filter.

 

Very short exposure to look for Supernova on 19 Nov 2017!Nearly 3 million Light Years away (NGC 0589)

Very core of our nearest Galaxy – Andromeda at 2.5 Million Light years.

Bit too big for my field of view (26′ by 21′). But nice pic of the inner dust lanes also 19 Nov 2017!

Right overhead at this time of year, so anyone with a mount and a camera with telephoto and FOV of about 2.5degrees, now is the time to image this spectacular sight.

 

Part of the Veil Nebula – Moon 75%!

Veil nebula is a cloud of dust and ionised gas (Sulphur Oxygen and Hydrogen) in the constellation of Cygnus.  It contains a radio source and is about 1470 light years away.

New software AA6 and Observation Manager script has improved accuracy.

The original data (images) have been re-scanned using new script.

UX UMA variable star.  14/8/2017

Interesting that a medium sized telescope can find objects orbiting stars 880LY away!

Yes, this is the result of a star measurement session. A time series of V filtered measurements of RW Tri at 880LY.
From this information you can estimate sizes of objects and rotational period.

It is 2017 and to start the New Year– Orion Nebular!

I just love this nebular.  Star forming area of dust and gas. This is a better image than before Xmas.
Two sets of exposures to get the core and the dust areas.

Techy bit:  3 x 100sec per RGB and 4 X 130sec L  merged with 3X 60sec per RGB and 4 X 60sec Luminance. Taken with 8inch RC astrograph with a Trius H694 camera running ar -12C. Filter system is StarlightXpress Mount is AzEq6 pro.

Cacoon Nebula 8 Sept 2016

Ok I have taken quite a good image of this tricky nebula.
Take a look on the web and look at some of the images.
4 X 400sec per RGB.  No darks. (had to manually take out a couple of hot ones)

M51- Good seeing and good target

My image of M51 in colour came out really well:
