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.

Clear night at Woodland Observatory – 8/10/2018

The sky was clear but a lot of heat rising from the ground. 3 X 300 seconds for R G B with RC Astrograph Processed with Observation manager 9.12e using Astroart 7 script interface.

 

 

Latest Spectra of bright star Phad in Plough

This is an easy one as it is an A0 spectral type.

Type Ao with SA200 grating

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)

Last night M51 -Bit windy so not quite round stars.

Not bad image considering the gusty wind. Just 3 X 300sec per colour

New Version of Observation Manager for AA6 – Now controls PHD2 also!

OK, I now have the controlPHD.exe and the AA6 script to control PHD2 from Observation manager scripts. Tested and now working on getting the new site up and running. Woodland Observatory – Selsey . Build the top of the observatory first 11ft square brick built.

Hope to get operational again in a month!!

 

M33 next to 30% moon.

Managed to get M33 as it was a clear but very bright night.

Monochrome Horsehead in Orion – Round Stars (Yes!!!)

Finally fixed the problem of round stars on long exposures. 6 X 600sec 8inch RC Astrograph and SXVR-H18 at -20degC
