FIASCO

FIbre Amateur Spectograph Casually Organized

Our second generation after PONCHADO

We've built three of these spectograph, the first one with a 512x512 front illuminated CCD camera as detector (in fact, the same camera as in PONCHADO). The second one with a 512x512 back illuminated CCD camera. These first two cameras were manufactured by Hale Research (UK) unfortunately out of the market nowdays. The third FIASCO was built with a 1024x1024 back illuminated CCD camera from Finger Lakes (USA).

 

	Picture of FIASCO. The configuration is the same as Ponchado but the reduction of stray light and mechanical stability are highly improved. As PONCHADO, it can be equipped with three different gratings: 600, 1200 and 1300 grooves/mm and blazed at 400, 600 and 500 nm respectively.
	Another picture of FIASCO without the top cover and with labels for its different components. In this configuration the photo-objective has been substituted with a simple doublet-lens like in the collimator.
