Navigating Tariffs: Due to the current volatile tariff environment and associated logistics challenges, O'Telescope is unable to fulfill shipments to the United States. Orders submitted with a U.S. shipping address will be refunded, with the payment gateway transaction fee deducted. This restriction does not affect BackyardEOS or BackyardNIKON, which remain available as digital downloads.
Inventory closeout sale, everything must go. Up to 35% off. Some conditions apply.
We are closing our inventory side of the business and focusing solely on software - going back to our roots so to speak. No store coupons required, all prices have been marked down. First come, first served, until quantities last. We are no longer placing orders with manufacturers. Absolutely no rain checks. We reserve the right to cancel and refund orders at our sole discretion. We do our best to maintain our inventory accurate, but mistakes do happen, if you purchase an item that is no longer in stock, you will be refunded. The sale does not apply to some higher-end items such as 10Micron. Prices subject to change without notice. ALL SALES ARE FINAL.
Occasionally, we find a box under a box under a box in the back of the warehouse with hidden treasures, and when we do, we add these items on the site, so even though you may not find what you're looking for today, it could automagically appear next week.

Optolong 1.25'' LRGB Filter [OPTO-LRGB-125]
$295.87 CAD$369.84 CAD2 in stock On saleBack Order / Waiting ListOptolong Filters: The LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colors. The LRGB filter set divides the spectrum into its components red, green, blue and luminance. OIII emission overlaps on blue and green filters with maximum transmission to allow high efficiency and natural color imaging. Gap between green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves color balance and separation.

Optolong UV-IR Cut 1.25'' Filter [OPTO-UV-IR-125]
$55.58 CAD$69.47 CADOn saleOptolong: UV-IR cut filter is designed for ultraviolet and infrared wavelength blocking to improve sharpness of the image as most of the optics are designed for the visible spectrum, because it’s very difficult to create a lens with the same focal point for the visible and IR spectrum.It is used on a digital camera and the video, which do not have an IR protection filter toward an image sensor or were remodeled. This is important because unfiltered CCD and CMOS sensors are extremely susceptible to UV and IR rays just outside the visible spectrum that can have a very negative impact on image quality.
