For light imaging systems.  Design is coaxial and square with the focuser eyepiece tube.  Target price <  $250.   Attaches to most focusers with eyepiece lock ring flange.  nFRAME controller (sold separately) uses same electronics as our usb-nSTEP with a "framing" firmware load.  Uses same stepper as our usb-nSTEP which means stepper can be swapped between focusing and framing with a simple change of the gear.   Interested?  Please drop me a e-line at rigelsys@cox.net

 

Here's a link to a short quicktime video of the nFRAME in motion.

Will you be able to control focus and rotator motors with one controller? I seem to recall that at one point you added two focuser capabilities to the controller.

 

looks very cool!

We have a controller in the works that will be able to control both a focuser and the rotator :-), or alternatively two focusers, or two rotators (think about that one).  Will also have handbox with pushbuttons and wifi.  Once we have a measure of interest.

The heart of the mechanics is the gear attached to a 2 "T-adapter" with 42mm thread for direct attachment to a DSLR T-ring or direct to a 42mm T2 compatible filterwheel or imager.  The T-Adapter provides coaxiality within the eyepiece draw tube and keeps the camera square-on with the focuser.  Pretty simple solution.  Beyond that the screws on the back tighten the teflon ring for tension on the gear for drag as as well as supporting the camera weight.  To attach to the focuser, assumes focuser has set-screw flange (most do) and thumbscrews capture the flange on the outside, with the T-adapter on the inside, provide very rugged attachment.  So in terms of components, its simple, durable and cost effective.  We use the same stepper as on the nSTEP focuser kits so that's interchangable.

Both of my Focusers are Moonlites so I hope that I’m covered. Lol

Any option for the scope side connection to be M48? Many flatteners and coma correctors for imaging present this connection towards the filter wheel/camera.

M42 female to m48 male adapters are readily available, such as this one.

Thanks for your reply.

 

M42 is OK, so long as both sides of the rotator use M42. My field flattened presents M48 male which I can reduce to M42 male.

Cool! How about the other side? How is it connected to the Baader focuser?

I’d be interested depending on price, weight capacity (must handle asiI1600+EFW8+OAG) and features.

4 thumb screws catch the lip of the flange on the outside, T-adapter tube captures the inside.  Firm attachment.

Modified hardware, moved cable socket on stepper to reduce length,  attached to a 2" Celestron visual back I found that has a flange,  prototyped the nFRAME electronics -- box uses one usb port, incorporates both nSTEP focus control and nFRAME rotation control.  Now have rotator under software control :-)

production version completed. Machined out of Delrin (slick surface and easy to machine). This one shows fittings to accommodate a 2" tele compressor, also will have one that supports 2" m48 attachments. Software is moving along, already ASCOM compatible, working with SGP.  Some more polishing to be done on the functions.  Should be out for testing in a few weeks!

SW is ready for testing (I have two volunteers to send out test sets to :-)  Here's what it looks like, running in parallel with an nSTEP app.  Displays position in degrees, 5 stored goto positions available,  can goto an entered position,  use in/out buttons to move 1 deg,  use Cin/Cout buttons to move until unpressed.  Rotary deg position dial display. ASCOM complaint, checked out with SGP.

Would this be able to be used as a derogatory for alt-az setups?

Haven't worked the software for that yet ... its a thought.

Our field tester has it running under SGP getting great results as described in his lectures at the IAS show in UK earlier this month.

How much backfocus will this take up? For a CCD/FW/OAG setup I am already tight. Putting this after the Field Flattener will probably not work.

In production :-)  See attached photos.  Introductory price for the usb-nFRAME + Frame rotation hardware and stepper is $599.95.  Note the usb-nFRAME will run both the framing stepper AND a focus stepper (either ours, or any robofocus/moonlite compatible unipolar stepper).  So you can have both focusing and framing in one package.  

 

Special offer, if you have a usb-nSTEP basic (PC only), you can send it in and we'll apply the full purchase price against the usb-nFRAME ($599.95 - $147.95 = $452)  as we'll pull the circuitry out of your usb-nSTEP basic and incorporate it into your  usb-nFRAME.

 

The nFRAME hardware comes native with an SCT (Celestron or Meade) compatible nosepiece for direct mounting to an SCT.  We also include a 2" to SCT male adapter that threads into the nosepiece for use with standard 2" focusers.

 

On the backside the nFRAME accepts the M54 thread common for many field flatteners. But to expand the universe we include an M54 to M48 male adapter for field flatteners that can be unscrewed from their nosepieces,  and/or direct connect to your camera stack.

 

The nFRAME adds about 53mm length to your imaging stack. 

 

For more info, drop me an e-mail at rigelsys@cox.net

 

thank you for your support!
