Secondary Mirror Focusing System

Optec's FastFocus Secondary Mirror Focusing System with FocusLynx Controller has proven itself to be a singularly unique solution to the limited back-focus of the Celestron EdgeHD telecopes.  With the FastFocus system in place, any Fastar compatible Celestron OTA can function like many professional telescopes where only the secondary mirror moves to adjust the focus. The primary mirror and entire imaging train can be locked in place avoiding flexure and tilt at the image plane.

Charles Olivier provided much of the "hands-on" testing for our first generation FastFocus system.  His review and results are available for download here

The M27 image at left was taken with a Celestron C1100 EdgeHD using the Fast-Focus C11 Secondary Mirror Focusing System.  Using FocusMax as his auto-focus software, the Fast-Focus system performs flawlessly even with incredibly small step size of just 140nm.  Second generation FastFocus SMFS focuser have a slightly larger 200nm step size.  Image courtesy Charles Olivier.

FastFocus is easily installed taking advantage of the removable secondary mirror of the Celestron Fastar.  Installation and collimation is as simple as the popular Hyperstar f/2 imaging system.   Retrofit kits for older Celestron OTA's are available to make them Fastar and FastFocus compatible.  Contact Optec Sales for details.

Optec's FastFocus SMFS system with FocusLynx was awarded aSky & Telescope Magazine Hot Product for 2012. The official award reads,

"We got our first peak at Optec’s FastFOCUS system for Celestron Edge HD Schmidt-Cassegrain telescopes at the Northeast Astronomy Forum last April.  Because the new telescopes are designed with a fixed optical back focus that leaves little room for a traditional precision focuser at the back of the telescope, Optec developed the FastFOCUS, which moves the secondary mirror by computer control using the company’s FocusLynx controller."

Optec's original press release from NEAF 2011 introduced the SMFS system.

Multiple Ways to Connect

The FocusLynx Control Hub acts as the central controller to link the FastFocus to any control PC.   The hub includes communication ports for Serial and USB (using Optec's USB/Serial cable) and wired Ethernet Network protocols as standard.  An optional WiFi board and antenna can be added and installed at any time.  Focuser 1 and an optional Focuser 2 port are available at the top of the FocusLynx hub with 12VDC Power, Network, optional Hand Control, and Serial connection ports available at the bottom.  An optional aluminum mounting plate makes it easy to mount the FocusLynx Hub to any telescope pier or mount. 

Using the ASCOM Local Server model, Optec's FocusLynx Commander software allows multiple clients to connect simultaneously to the FocusLynx hub.  Additionally, embedded webservers in the wired Ethernet and WiFi connections enable FocusLynx to generate a control interface accessible through any web browser or smartphone. Free Android and iPhone applications search the local network and load the interactive webpages.  Because these pages are generated by the hub itself, once you are connected, there is no further configuration required: just connect to your focusers and enjoy remote wireless focus control with the optional 802.11 WiFi add-on. 

Multiple Client Connections

Any ASCOM client, Mac users of TheSky X or Equinox, or any web browser can be used to control the FastFocus focuser attached to the FocusLynx hub.

With the optional FocusLynx WiFi module installed, the FastFocus can be controlled through any iPhone or Android device. 

Multiple Options Available

Each FocusLynx package comes complete with everything needed to connect.  An optional Hand Control, WiFi add-on board, second stepper controller, mounting plate, precision external temperature probe, and motor-specific cables round out a complete integrated package. 

Contact Optec Sales or any of our Dealers for a system specifically configured for your telescope OTA and observatory.  FastFocus systems for the C-11 and C-14 (including the EdgeHD OTA) are available from stock.

FocusLynx Commander Software

Visit the FocusLynx Software Downloads Page for the latest updates and ASCOM driver, FocusLynx Commander control software and additional resources.

ASCOM StandardsFocusLynx Commander creates an ASCOM Local Server or hub to allow multiple clients access for communication and control of the attached focusers.  By using the local server model, FocusLynx offers an easily configurable user experience for all Windows ASCOM programs.

Exceptional Mount

A couple of years ago, I wanted to replace my old VMA200 mount with something more modern.
While visiting the Paris Astronomy show (RCE 2012) I noticed the Nova120. At that time, it was a brand new offering that I have not seen before, hence my hesitation to purchase
I wanted to purchase a E.U product to guarantee the quality and ease of access to support in my own language. I checked the forums and heard nothing but good things about the Nova120 so I decided to purchase it.

I have used enough astronomical instruments in the last 30 years to know what great quality is. The Nova120 coupled with the PRISM v10 and a CDK20 (508 mm) helped me pull off 900s unguided images with great ease. (Raw FITS File here). Payload of this setup is about 80 kg (160 lb).

The dizzying slew speeds, excellent accuracy and painless tracking makes this hobby easy and enjoyable again.
After using this setup for a year and a half, the only problem I had was rebalacing the gear after changing scopes. The superb electronics and software included make this tasks even more easier that just eyeballing the scope for movement due to unbalance.

You can very easily watch the motor consumption and know where the unbalance is....that easy. I have so much data that it is becoming difficult yo keep up.
I have absolutely zero regrets, this purchase has made everything easier: No summer/winter worm-gear adjustments, no guiding... just start imaging night after night after night.

Imaging Made Easy

Prism is my GoTo program for observatory control and imaging. Prism's many features make imaging taking a breeze.

I was concerned about giving Prism a try , especially as its quite expensive. So far Im very impressed and glad of my decision.
Im a beginner at all this so haven't tried other more recommended software, Prism appealed as it seems to do everything instead of using several programs 👍🏻

Great lightweight guide scope

This guide scope replaces a 400/80 that was waaay too heavy for what it did. The smaller 60mm scope does a great job guiding and I can RA balance with just one counter weight now - much better - and it looks like something Ferrari designed

Still learning Prism using Wireless links...

I have much of your software working at this time... I have it parked on my main computer, and a notebook... My main computer is a OverClock computer with 32 Gigs of RAM Clocking presently at 4400MHz with software parked on SSD drives... The rotation dome by NexDome is still not working... Most problems like this have to do with ASCOM Drivers... There is not very much detail information on how to use this software... I have to feel my way to a total operational staus... Second issue... The rain in the San Francisco Bay Area this year has limited my access to my larger telescope (12 inch SCT)... This rain has been so significant, I was force to weatherize my observatory... My goal here is,,, I am trying to remotely control my observatory totally. I have used Netgear Powerline 2000 to handle camera images and discover controlling rules to do that... High speed is vital for images with cameras over 3 Megs... I have both 12 Mega sensors and 24 Mega sensors... I am also using Netgear Nighthawk router and its mating extender to increase control signals to my observatory that is about 100 feet on the side of hill... I am also using Virtual Here software on a Raspberry Pi inside the observatory to solve the USB interface requirements... I started out using Model B and B+ on level 3 raspberry Pi's... I have moved to Level 4 Raspberry Pi to gain access to USB 3.0 technology... Big difference! I hope by early spring to have everything working... Bob Ritter MicTechS
