| 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 |

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

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 |

| 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. |
