Starting Price: $0.00
Price as Configured: $0.00

Brand: Telescopi Italiani / SKU: TI-35-5.0

The Italian Telescopes TI35 f/5.0 is a 350mm aperture astrograph built for imagers who want 1750mm of focal length, an exceptional 87mm diffraction-limited corrected field, and a design light enough to travel. Its Modified Harmer Wynne optical system with three-element ED corrector delivers true diffraction-limited performance from 400nm to 1.2 microns — covering broadband, narrowband, and near-infrared imaging in a single instrument. Deep Space Products is the U.S. dealer for Italian Telescopes and can help you pair the TI35 f/5.0 with the right mount and imaging train for your setup. Contact us to discuss your configuration.

Ordering and pricing

The Telescopi Italiani TI35 f/3.5 is a built-to-order instrument available exclusively in the United States through Deep Space Products. Please contact our team for current U.S. pricing, option pricing (quartz mirrors, field rotator, dust cover, dovetail system), lead time estimates, and shipping logistics. All orders are coordinated directly through DSP.

Payments are due as follows:

50% due at the time of the order
30% due once the optics are complete (photos and interferometric test report will be provided)
Balance due one week prior to shipping

The order may be canceled before shipping, but 50% of the total amount paid to date will not be returned. The remaining 50% will be returned within two months.

Any delay in payments will result in a coorepsonding postponement of the telescope's delivery date.

Control Software

Telescopi Italiani telescopes include proprietary Wi-Fi telescope control software. The integrated secondary focuser and optional automated dust cover and field rotator are ASCOM Alpaca compatible and work with standard observatory automation platforms including N.I.N.A., Sequence Generator Pro, and ACP.

Optional factory accessories

Fused Silica (Quartz) mirrors: Near-zero CTE upgrade for both primary and secondary — recommended for remote installations with significant temperature variation
TI110 Field Rotator: ASCOM Alpaca compatible — for precise framing control or alt-az mount de-rotation
Automated Dust Cover: ASCOM Alpaca compatible — essential for unattended remote operation
TI-112 Dovetail System: Quick-release dovetail for fast, repeatable OTA balancing

Also available: TI35 f/3.5

For maximum data throughput on large emission nebulae and narrowband targets, the Telescopi Italiani TI35 f/3.5 (1,230mm focal length) delivers the same 350mm aperture at a super-fast focal ratio — collecting data roughly twice as fast per sub-frame with a wider field of view that frames expansive deep-sky objects in fewer panels. Both models are available exclusively in the U.S. from Deep Space Products.
