About Astrojohn

I am a science geek! Interests Astronomy, Skiing, Philosophy, basically any form of technology including writing automation software for my observatory. I will also share this with others using the same EQMOD/Astroart tool set.

M51 2X300sec per colour

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

AAVSO Award!

Time flies when you are busy!!

Minimal Observation Manager Freeware added to download.

Version 9.12c is in downloads now.   Minimal configuration with only essential files in folder.

Still needs to be configured for your system.

 

All the best

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 […]

Even more accurate binary data using AA6 SP3 and new camera.

UX UMA new data using new camera and new software AA6 SP3.

The zero point is Mag 14 the time is 2017-08-27T 23:16:19.5′ / LT for start of image exposure 80sec.  The orange is the check star.  The measurement is done against 3 reference stars from AAVSO.

V Filter (Green) and the setup was Camera […]

Captured an eclipse of a binary star system 13 years ago!

Yes, we are looking back in time for every star we observe. This one is designated UX Uma, in the ‘Plough’. The binary star system is 13.06 Light Years away. So last night I watched as a smaller dwarf star passed in front of a larger star but they are very close together. So my […]

Astroart6.0 SP2 is available! With scripted auto photometry for variable stars.

Yes, with a simple script you can image the variable stars, using a list of variables and reference/check stars you can produce your BAA or AAVSO reports direct.  Either at the time of imaging or as two separate processes.  It is really great and many thanks to the guy’s at MSB (Astroart software team) http://msb-astroart.com […]

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.

RW Tri Time Series.

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. […]

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)

RGB Image of Cacoon Nebula
