Hap Griffin Astro-Cables
and
DSLR Astronomical Accessories

 

 

Astrophotography for the amateur has been revolutionized by the latest generation of Digital Single Lens Reflex (DSLR) Cameras by Canon and Nikon.  We supply several of the key components required to make long exposure astrophotography with these cameras possible.

    All photos taken with modified Canon 300D and 350D DSLR's

 
 
While the more recent models of Canon and Nikon cameras can be fully controlled from a USB cable with the proper software, the older models require a special long exposure cable connected to their "bulb" port to achieve exposures longer than 30 seconds.  For Canon cameras, I offer a wired cable that plugs into a serial port on your PC, and for those without serial ports (i.e. most modern laptops) a USB-to-serial adapter to allow the serial cables to be plugged into a USB port.  For Nikon cameras, I offer a wireless infra-red controller that plugs into a serial port on your PC.  It can also be used with the USB-to-serial adapter I carry for those who have only USB ports. 

The Canon models that require a long exposure cable are the 10D, 300D, 350D(XT), 400D(Xti), 20D and 30D.  All models more recent than these do not require a special cable for long exposures.

 
Software applications known to be compatible with my serial cables:
 

ImagesPlus (www.mlunsold.com), by Mike Unsold, provides an on-chip focusing routine, automated series' of long exposures and a complete suite of software astrophoto processing tools second to none.

Maxim DL (www.cyanogen.com) ...another Swiss Army Knife all-purpose tool for DSLR and CCD astrophotographers. 

DSLR Shutter (www.stark-labs.com) by Craig Stark is a free application for automating imaging sessions.

Nebulosity (www.stark-labs.com) by Craig Stark is a full featured capture and processing application.

Backyard EOS (www.backyardeos.com) a comprehensive capture and automation tool for DSLR astrophotography.

iAstroPhoto (http://www.stevepur.com/astrophotography/iAstroPhoto/index.html) - for MAC users.

Please note that these programs require that the USB cable supplied with the camera to also be connected for downloading images, setting capture mode, ISO settings, etc.  The long exposure cable does not provide "communications" with the camera and is ONLY used to directly control the shutter via the camera's "bulb" port to over-ride the 30 second exposure limitation imposed with the standard USB connection.  

My cables feature:

  • Very flexible two conductor cable with shield - will not cause stress on camera or telescope mount
  • Custom cable strain relief
  • Each cable individually hand-made to order and fully tested before shipment
  • Full year warranty against faulty parts or flaws in workmanship

Here's what my customers say:

  • JC - "Very impressive service."
  • SW - "Just wanted to let you know I got the cable yesterday - tried it out last night and everything works great.  Many thanks for the excellent work!"
  • PC - "Cable arrived today. Looks good & works perfectly. Thanks Hap."  
  • JP - "Thanks very much. I received it today. I'm absolutely delighted with the product. The quality is very high and it all works perfectly."
  • DC - "Everything arrived ok! Thanks for such a quick turnaround!"
  • TA - "Just to let you have an update, that the whole system works like a dream.  DSLR shutter + Hap Griffin's modified Canon remote cable (what a perfect piece of work)."

For owners of the Canon "Digital Rebel" (300D, 350XT, 400XTi, 450XSi)...

These cameras use a 2.5mm 3-conductor male plug for connection to the camera.

The serial cables can be used with our USB-to-serial adapter to enable USB control for laptops and PC's that have no serial port.

For owners Canon Pro DSLR's (D30, D60, 10D, 20D,20Da, 30D, 1DS, 1DS MII, 1D MII, etc)...

These cameras require a special proprietary Canon connector known as an "N3".  This connector is only available on devices manufactured by Canon such as the TC-80N3 Timer Remote Controller, the RS-80N3 Remote Switch, the RA-N3 Remote Switch Adapter, or the ET-1000N3 Extension Cord.  Along with the order for a cable, the customer must send me one of these devices to modify.  I will insert a male and female 3.5mm 3-conductor plug and jack into the device's cable so that when plugged together, the device can be used normally.  However, the camera end of the cable with the N3 connector can also be unplugged and used with a serial port cable that has been configured with a mating 3.5mm 3-conductor plug.  If you don't have a Canon N3 accessory to send, contact me directly and arrangements can be made for me to purchase the accessory and include it in your price.

The serial cables can be used with our USB-to-serial adapter to enable USB control.

IR Remote Controllers for owners of the Nikon D40, D50, D60, D70, D70s, D80, D90, D3000, D5000, and D7000...

ImagesPlus, Maxim DL, DSLR Shutter and Nebulosity support control and sequencing of long exposures with selected Nikon DSLR's via an Infra-Red Remote Control.  The NIRS series of controllers listed below are composed of a custom micro-controller driving an infrared LED in a small package that can be mounted on your telescope with Velcro (supplied) or otherwise in a position where it will illuminate the front of the camera when in use.  The controllers include an integral serial port cable and obtain their operating power from the port itself so battery replacement will never be required.  

Be sure that the software you intend to use is compatible with your camera AND this cable.

The serial cable can be used with our USB-to-serial adapter to enable USB control.
