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.  
Screw Together Filter Holders 06/06/2102  Here is a new way to keep your filters handy.  These "Screw Together" containers each hold one filter. The top of one screws into the bottom of another so they can be kept together.  A nice compact way to store your 1.25" or 2" filters. 

2" come as 4 pack with one lid

1.25"  comes as 6 pack with 2 lids
Spectroscopy of Filters.  Have 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.    Read this article  on what I have learned so far. 05/27/12

Check out the used/one of a kind sections! There are some new items there and a few more yet to come.

04/11/2012 Note:  We got a new shipment of keyring red LEDs in and got a really good price on them. Because of increased shipping costs, we were unable to lower the price of a single one ($4), but have dropped the price of 5 to $12 shipping included in the US.   You can get 5 for the price of 3.
Recent Catalog additions:
The Nomad catalog of stars to about magnitude 20 is now available for Skychart (Carte du Ciel).  Since the download procedure is so time consuming, I am providing a copying service for the final installable compressed catalog.  See Skychart (Carte du Ceil) Nomad Catalog Copy Service for more information

I put a Moonglow Technologies All sky camera up at my NM home.  Now I can see the whole sky all the time from anywhere.   I was so impressed I have become a representative for the product.  Take a look at this comparatively inexpensive product that works both day and night and see how it can help you see more by allowing you to see what is happening outside.  For more details see my page on my installation
4 Channel Temperature Data Loggers - see how fast your observatory and/or telescope reaches thermal equilibrium

Log 4 channels of 520 data points at any interval between 2 seconds and 3600 seconds (one hour).  Download the data to your spreadsheet for analysis. Available in a USB and serial port version.



Blinking red led attached to a 9 volt battery connector.  Great for safety use at public starparties.  $0.80 each and $1.00 shipping in the US no matter how many you purchase.  See the red led section for more info. (12/20/2011)

Use and  Astro-Mall and Astroclassifieds.com for buying and selling your used equipment.  They are great free sites!  Unlike Astromart, there is no $15 fee to sign up or to change your email address or other data. (and they still claim it is a free service.) Even if you post your stuff on Astromart, post on these too and  help them grow.  Competition is a good thing. There are more and more people finding these sites friendlier and cheaper to buy and sell on.  Besides, Herb has kicked so many people off that you will have a whole new audience.   I was booted because I politely questioned the high prices of Astromart ads and their latest increase.  His reply:  "You are history"   So consider my website a historic site!
Also check out http://www.astronomyratings.com/   and rate the equipment you have purchased so that everyone can benefit.
Golden State Star Party is coming! more info here!
Have a yearly Starparty?  I will be happy to put a link to it here.
