About Siebert Optics

Hi, my name is Harry Siebert, and  I have been an amateur astronomer for many years.   Like many, I cannot afford to spend a fortune on telescope accessories.  So through much study, research and experimentation, I have designed affordable telescope accessories for myself and others.  Siebert Optics strives to give the best quality at the most affordable prices for any astronomer, whether a newbie or advanced in the hobby.  Please feel free to ask any questions you may have either via email or phone at the above number.  Siebert Optics is a small company so feel free to ask for me specifically.

The pictures below were taken by myself with an inexpensive digital camera, my 10mm eyepiece and my f/7.3 Dobsonian.  Not bad for a beginner astrophotographer.
