When it comes to expanding your SeeStar's imaging capabilities, adding a filter is your best bet, and Apertura has created a solid, premium, and simple solution with this Aluminum 2" Filter Holder! Better yet, this precision CNC-machined accessory won't break the bank, providing you with a quality upgrade for your ZWO SeeStar S50 Smart Telescope. Don't pay a premium price for 3D printed parts when this premium construction is available at a great value!
While the existing Duo Band filter built into the SeeStar offers a good way to boost contrast on nebulae, it can be a bit too aggressive for broadband images. With the Apertura Aluminum 2" Filter Holder for SeeStar Telescopes you no longer have to make do with the the built in filter; you can choose the filter profile that is right for you! CNC machined out of 6061 aluminum, finished in a durable bead-blasted oxide and with M48 threading, this holder securely and smoothly accepts virtually every 2" astronomy filter on the market today. Connecting the Apertura aluminum filter holder to your SeeStar S50 is a breeze as well: simply thread your filter of choice into the Apertura Aluminum 2" Filter Holder, insert it in front of the SeeStar's front objective just like you would with the stock solar filter, and your smart telescope is ready to go. Incorporating this filter holder into your Seestar setup does not change the control or function of your Seestar, so you can proceed as you normally would and enjoy your enhanced view into the night sky!
A Powerful, Premium, and Solid Upgrade!
The SeeStar S50 is already an advanced and powerful package, but the Apertura Aluminum 2" Filter Holder takes things even further with solid 2" filter mounting, durable and stylish construction, and simple integration with your smart telescope!
Push the Sky's Limits
The duo-band filter built into the ZWO SeeStar S50 smart telescope features a 20nm Ha band and a 30nm OIII band. While this does a good job at giving deep sky images a boost, it can be less than optimal for some targets, forcing you to choose between either a less suitable filtering profile or no filtering at all! With the Apertura Aluminum 2" Filter Holder you don't have to settle any longer. Choose the 2" imaging filter that's best for your seeing conditions and goals. Please Note: While this holder can accommodate most 2" filters on the market today, please keep in mind that the maximum exposure time for the SeeStar S50 is currently 10 seconds. Accordingly, while it may be possible to use more aggressive filters than the integrated duo-band filter, maintaining functionality with these is not guaranteed.
Premium, Durable, and Stylish
This filter holder has been precision machined out of solid aluminum, so you can rest assured this will be an upgrade that will last. With precisely cut M48 filter threads, this holder provides a simple, secure, and durable mounting solution for your imaging filter. The stylized design and black oxide finish also help the Apertura Aluminum 2" Filter Holder match the sleek style of the SeeStar S50 smart telescope. Designed to use the same gentle yet secure press-fit installation as the stock solar filter, adding this premium upgrade to your SeeStar is simple. Just install your 2" filter of choice into the holder, press into the front of the SeeStar, and it's ready to use!
