Obtaining  a spectrum of a filter

Trouble with the site?  If you have any trouble using this site or placing an order, please let us know.  Email: duchekcs@duchekconsult.com

Note: we respond to all orders with a confirming email and and estimate of when it will be shipped (today or tomorrow usually).  That email will be sent within hours, definitely less than a day.  Occasionally paypal will not notify us of an order and we do not know about it.  If you do not get a confirming email for your order within 24  hours, feel free to contact us as it means we do not know about it.  

Spectroscopy of FiltersHave you ever wondered how you could check the light transmission on the filters you use?  Companies often include a spectrum with a filter.  They often do not.  Are you curious to see what a filter's spectrum looks like before you buy?  DCS is making that service available.   

Unfortunately, the Allsky cameras that we advertised here are no longer available.  10/17/15
