Jupiter taken with DFK21

Jupiter January 2014

This was taken on Sunday 19th January 2014. I took it on my Altair Astro 8″ RC with a 2x Televue Barlow and an Imaging Source DFK21 (Colour Camera).

It took me a while to get the options in the ic Capture Imaging Source software correct, but then I stacked it in Registax 6.

I imaged for about 50 seconds at 60fps. But maybe only ended up using about 500 frames, the seeing was not great.

Upgrading the Observatory PC from Windows XP to Windows Vista

The support for Windows XP is finishing in April 2014. So really it was time to upgrade the observatory PC. I was previously using Windows XP Professional 32bit edition for quite a while in the observatory. I had no real issues with it, and I know a lot of people still use Windows XP on their Laptops or Desktop PC’s for running their observatories.

I had a spare copy of Windows Vista Business 64bit lying around, so I decided to use that, instead of paying £50 or more for a copy of Windows 7. Come to think of it, it would have been a lot more as I would ideally have wanted the Business edition of Windows 7 which can be quite pricey (as I like to remotely control the observatory PC from in the house by using Remote Desktop Connection and that’s only available if your Windows PC is the Business or Professional editions).

My main worry when upgrading was drivers, and especially 64bit drivers! I went for a clean install of Vista and after it was complete I was amazed to see that the internet was already connected (so the ethernet driver had been installed for me) and the sound was working (so sound driver installed OK), and it had installed the driver for my USB Hub PCI Card. As I use about 8-10 USB ports on my observatory PC.

A great surprise and my biggest worry was my old NVidia graphics card which runs 2 monitors, but once Vista started to do it’s hundreds of extra updates – which took it to  service pack 2, the graphics card was recognised and the driver came from Microsoft and everything worked.

So that was the basic drivers, now came the main astronomy software, namely:

ASCOM 6 Sp3EQMOD
FocusMax
QHY5 software
Atik drivers
Maxim DL
Lakeside Focuser drivers
Starlight Xpress filter wheel drivers
Imaging Source ICapture and Drivers

Before the install I had backed up my FocusMax settings, Maxim Configurations and my EQMOD settings (as my EQ6 mount was still parked).

I had no problems installing any of the software on Vista 64bit, and once the main software was installed I overwrote the default settings files with my own backed up ones.

The only problem I ran into was with the classic USB to Serial adaptor software drivers, as I have 3 of these. 1 for EQMOD, and 2 for the Lakeside Focusers. There are so many different USB to Serial adaptors. I bought mine from eBay. I kept the original CD driver disks, but there are usually newer drivers if you know where to look and make sure you get the correct driver – as there seem to be hundreds of different ones.

Then it was a matter of checking which adaptor was set to which COM port and then telling EQMOD and the Lakside ASCOM software which COM ports these were. I then fired up Maxim and checked all the connections worked to the cameras (QHY5 and Atik 314L+), filter wheel and EQMOD.

Early days yet, as there is no real test like actually opening the observatory roof up and doing some observing or imaging to really test the software and Vista 64bit.

I am glad I left the PC in the observatory whilst doing the upgrade, as it meant I did not need to unplug any of the many cables in the back of the PC. Plus as it was a Professional version of Windows I could go into the house and use Remote Desktop Connection to remotely install and test the software without sitting in the observatory.

Now I shall stick to Windows Vista until they drop support for that, which hopefully will be a while yet. Then I suppose I shall be installing Windows 7 Business 64bit.

BTW my PC specifications are: Core 2 Duo 2.4GHz CPU, 3GB RAM and 500GB SATA Hard Drive.

 

The Complete Guide to the Herschel Objects Book Review

The Complete Guide to the Herschel Objects

Complete Herschel Objects BookThe beginning of the Herschel Objects book gives a brief introduction to the Herschel catalogue and then talks about William Herschel the telescope maker and the various telescopes that he made.
The book is broken down into each of the constellations. Within each constellation chapter are the details in turn on each of the deep sky objects in the Herschel catalogue.

Not all objects are given an image, (sometimes you get a sketch) but you may expect this – seeing that there are sometimes lots and lots of objects in a constellation. Each object is provided with a classification code, a Herschel number, the location, its physical dimensions, the magnitude and a description of the object.

The Complete Guide to the Herschel Objects is a complete guide and it’s a great reference book. It would have been nice to see colour images instead of black and white. It would also have been nice to see full colour images for every Herschel object on its own page, but due to the sheer number of objects that is just not possible. This is a shame as one of my favourite books is the Messier Complete Atlas that Cambridge University Press publish and that is full colour and really well laid out.

The Complete Guide to the Herschel Objects is available at Waterstones
