There hasn’t been a huge amount of progress since the last report.  The only change to the array is that I’ve now added the second Sky 90 to the frame as I now use the lightweight Celestron 80mm refractor to guide the Hyperstar on the C11 as the Sky 90 was a bit too heavy and led to poor tracking.

However, this Christmas break I have decided to try and get some funding to put the rest of the observatory together for the mini-WASP array - so retailers are currently being pestered for their best prices.  I hope to be able to submit the grant proposal early in the New Year and will keep you informed of any developments.

It is just as well I don’t have the funds available to proceed with the mini-WASP concept as it has given me time to think about the whole system.  Since coming up with the idea of multiple imaging scopes to effectively cut down the total imaging time on an object, I have had real trouble trying to couple the colour imaging system with the narrowband imaging system.  Basically, no combination of scopes and cameras could cover what I wanted to achieve.

But sometimes a walk with the dog over the forest can achieve wonders, and it came to me that I should not try to combine both systems in one.  It would make far more sense to keep the Hyperstar III system as is for taking the colour data, although this will mean a 4-frame mosaic for each object, and use the mini-WASP array with its FSQ106 scopes and 35mm format mono cameras for just taking the narrowband data.  The colour and narrowband data can then be put together by Noel to create unique wide field images.  In addition the framework of the mini-WASP can be adapted to hold up to 10 scopes plus a finder scope, so this flexible system allows for a variety of FOVs to be taken.  Since the mini-WASP array will now only be used for narrowband imaging I have renamed it the Narrowband Imaging Platform or NIP.  Now all I need is a substantial Lottery win!

The mini-WASP framework was delivered to the New Forest Observatory by the CEO of NTE Poole, Eric Kennedy, on Wednesday 5th December 2007.

If you have just joined us then make sure you read all about the mini-Wasp Array Project from the beginning.

The accompanying photos show the all-Aluminium black-anodised mini-WASP framework with the Megrez 80 mm guidescope, and one of the two Sky 90 imaging scopes attached. 

The fourth aperture will be used to house a Takahashi FSQ106 with reducer/corrector, camera rotator and filter-wheel.  The imaging camera for the FSQ will be the Starlight Xpress monochrome H36.

The next component I need for this project is the one that will cause the longest delay - it’s the mount!

In my last post I was at the point of deciding which refractors and CCD cameras to use.  I think I’ve now solved that dilemma!

Having gone through many combinations and permutations I am thinking the best solution for me is as follows: (more…)

As I said in the project announcement, living in the UK we have a major problem to contend with trying to pursue our hobby - the weather!  There are very few good clear Moonless nights to take those perfect images.  I have also compounded the problem by moving from a very fast (Hyperstar) imaging system that worked at f#1.85, to a much slower refractor-based system working at only f#4.5, i.e. six times slower. 

The problem I am trying to solve is how to get as much image data as possible in the short time allocated to us during the year.  One way of increasing the data is to parallel up the imaging, that is, to have several identical optical imaging systems all imaging the same object at the same time.

The name for this project comes from the Wide Angle Search for Planets or SuperWASP project.   As you can guess it is used for hunting exo-planets.  

If you look at the SuperWASP site you will see an impressive imaging array comprising 8 Canon 200mm f#1.8 lenses with their associated Andor CCD cameras all sitting on a massive torus fork mount - certainly very nice gear!

I’m going to tackle this problem piece by piece and I will be posting details of my thoughts in the mini-WASP Array category.  You can also see a list of the posts below:
