I wish we had North-American Summers

I'm sitting here, typing this, under lead coloured skies. It's cloudy, miserable and but warm.

On Monday June 25th. I was fortunate to be blessed with a very clear sky, and as I was on holiday. I decided to meet up with Paul Canon, for a night of imaging.

We travelled to our new location, Teggs Nose country park, which is only  three miles from where I live. But what a difference it makes. The skies are dark, with magnitude 5.1 stars visible to the unaided eye.

I wanted to test my little 2.5" William Optics Zenith Star 66SD, to see how good it is for CCD and DSLR imaging using my modded Canon 1000D. I will be using this telescope from  now on, because it is easy to handle but also. Doesn't require collimation as my Orion 254mm f4.8 does.


I decided to image NGC 7000 on that night. NGC 7000 or The North America Nebula. Is a huge hydrogen rich nebula, situated to the upper left of the bright star Deneb. It is huge, and only suitable for imaging with a DSLR or a CCD camera, with a big sensor.  And short focal length refractor or camera lens.

I used my little APO and Canon 1000D and took various exposures, to see how long I could go, before my skies were to bright.

The image here is the result of many short exposures with the longest, 300 seconds.

When you look at it. You can see why it's has earned the moniker of  the North America Nebula.

But I wish we could have their summers and their temperatures.
