IFW 3" Intelligent Filter Wheel

$1,350.00

To meet the needs of the ever increasing CCD size used in astro-imaging, Optec has designed a larger cousin to the IFW 2-inch. The new IFW 3" (full 3-inch clear aperture) supports a large variety of filter sizes with the ease of selection that is the hallmark of the IFW 2-inch. Three different types of interchangeable filter wheels are available: 58mm square with 5 positions, 50mm square with 6 positions and 50mm round with 9 positions. The 58mm square filters are a new standard available only from Optec. All filters are mounted using convenient delrin plastic tabs and spacers.

When used with the 3-inch couplings to the telescope and instrument package, either 58mm or 50mm square filter wheels can be used. These adapters and couplings are the same as what is used with the TCF-S3 and the Pyxis 3-inch instruments. Removing and installing a different wheel is as easy as with the IFW 2-inch. A side door is opened and the wheel removed after releasing the center axis hub. After the HOME serial function or HOME button is pressed, the wheel ID is identified and the new stack of filter names are available to the control program or display on the control box. For the 50mm and 58mm square filters, three filter wheels with unique ID are possible. There are two wheels available for the 9-position 50mm round filters

The 50mm round filter wheels are intended for 2-inch adapters and couplers for both the telescope and instrument package. These adapters are the same as what is used with the IFW 2-inch and TCF-S products. The 50mm round filter wheel is not intended for use with the 3-inch adapters.

Note: The IFW 3" is a massive unit that measures 10-inches on a side and is 2.5-inches thick including both the telescope and camera side adapters. At 7 pounds, a large telescope with capable telescope mount is required. A variety of telescope mounts are available to fit, and a very complete line of 3-inch drawtube adapters are available.

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

A great program, even for beginners!

I have to admit, I was hesitant to invest in an “all in one” astrophotography program. Being a beginner, I thought the learning curve would be way too steep, but after talking with several friends I decided to give it a try. The first thing I noticed was the logical layout of the main screen. It was very intuitive and easy to navigate. Everything you could need for astrophotography is in this program! Setup of my equipment was quick and easy with no glitches or errors. Everything runs smoothly from capture to the final process. You will surely have questions and this brings me to the next point. Prism’s customer service is second to none! With on line tutorials, a Facebook group and email you will have instant access to knowledgeable users worldwide. My first question was answered directly by the US distributor within a matter of minuets! Take the next step and invest in your future in astrophotography! You’ll never look back!
