Sharpstar SCA260 f/5 Aspherical Cassegrain Astrograph V2

Description

SCA260 V2Final versionis in stock and will be shipped within 3 working days of ordering

IMPORTANT NOTE: Sharpstar SCA260 has since released a slightly modified version (which can be treated as Ultimate Edition 2, even though they're still calling it version 2) in which the rotator has been moved to between the telescope tube and the focuser, so the focuser can be rotated as well.

From November 12, 2022, the SCA260 we sell is Ultimate Edition 2

Ultimate Edition 2: Now includes a pair of handles at the rear of the tube for easier handling, an upgraded focuser/rotator, and a free 1.25" collimating eyepiece.

Our store has taken pictures of the SCA260 Ultimate Edition 2 and will update them soon

Important notes - please read before purchase:

1.Most of these units have several fine sleeves/thin scratches on the tube surface if viewed at the correct angles. The manufacturer informs us that this is a characteristic of the finish and not a defect. See the product photos above for some sample images.

2. The focuser on this scope works perfectly but is a bit noisy. Again, Sharpstar assures that this is not a problem and we have found the focusers to be consistent across our stock.

3. Even though these scopes arrived very well packed from official delivery, several boxes came with the cuts in the inner/outer box flaps as pictured above. However, these do not compromise the safety of the scope in any way.

Product Description

This SCA260 is the latest V2 Astrograph from Sharpstar with a large aperture, fast focal ratio and well corrected wide field.

Designed for use with camera sensors up to full frame.

The optimized SCA260 is designed with an aspherical mirror which requires more sophisticated research and development. The process of producing, manufacturing and testing is more complicated compared with that of an ordinary reflective mirror, and the Pyrex-like material used is more stable than those traditionally used. The telescope is wrapped with durable carbon fiber material, which is lightweight, durable, and beautiful.

Both the primary and secondary mirrors of SCA260 wear enhanced aluminum coatings, which ensure they can achieve a high reflectivity of more than 95%. We further simplify the optical axis mechanical structure.

A 3" large corrector, featuring a three-element lens structure, is laid in the optical path, enabling the whole optical system to better achieve full-frame imaging and control the vignette.

The delicately pierced handle bar is completely made from CNC-manufactured aluminum, which can be used as a base for the attachment of other accessories, optimizing the supporting mechanical construction and decreasing its weight.

Based on the original, Sharpstar upgraded the travel length of the 3.35" dedicated focuser to 50mm for greater practicability. Also, Sharpstar upgraded the load of the focuser to allow you to add the accessories as you like, ensuring no slippage and smooth operation when shooting with accessories.

Sharpstar also added a 360° rotator at the rear back of the focusing device, now there's no reason to worry about the EAF data line getting entangled in the process. Three section M68X0.1 thread, M54 × 0.75 thread and M48. In the 0.75 thread adapter ring, a built-in 2-inch filter thread is added to meet different needs, facilitate connection to most imaging terminals on the market and perfect focusing.

1.3 What if I want to specify a shipping method for a free shipping item?
If you want to specify a particular shipping method (e.g., UPS or DHL) for a free shipping item, please contact us before placing your order. You will need to pay additional shipping fees, and we will ship via your preferred method.

1.4 What if I buy multiple items, some with free shipping and some that require shipping fees?
You can place your order as usual. You only need to pay shipping fees for the non-free shipping items.
If you want to specify a shipping method or have other special requests, please contact us.

1.5 How long does it take to ship my order?
After receiving your order, we need some time to process it.
Orders received before 5:00 PM China time will be shipped within 3 days.
Orders received after 5:00 PM China time will be shipped within 4 days.
Orders placed during Chinese public holidays may be delayed by 1–2 days (due to courier holidays).

1.6 When will I receive my package?
Delivery time varies depending on the shipping method used:

• 4PX, Postal Services, EMS, etc.: about 15–25 days
• UPS: about 7–15 days
• FedEx: about 7–10 days
• DHL: about 5–9 days

These are estimated times. Actual delivery is subject to the carrier's schedule.

If your package tracking has not been updated for a long time, please contact us.
If you haven't received your package after a long period, please contact us.
If there are any other irregularities, please contact us.

Please note:
After we ship your package, it may take 2–3 days for tracking information to become available.
Based on our experience, packages shipped to South America and Central Asia typically take longer.
Shipping around public holidays may result in delays due to carrier workload.

If delays occur, we kindly ask for your patience and understanding. We share the same desire as our customers—we hope every package is delivered quickly and safely.

If you want a faster and more secure delivery, we strongly recommend choosing UPS, FedEx, or DHL.

1.7 What does it mean when tracking shows "Label Created" but the order hasn't shipped yet?
When we provide a tracking number, your package has already left our warehouse.
However, the tracking status may show "Label Created" or "Awaiting Package" because the package is still en route to the courier's sorting facility.
Due to China's vast geography, transit between cities can span over 1,000 km, so it takes time.
It may also be undergoing export customs clearance. Your package should be delivered soon.

If your tracking status doesn’t update for a long time, please contact us.

1.8 What if my package needs special delivery instructions or other requests?
If your shipment requires an invoice to be attached, special packaging, delayed dispatch, or other requests, please contact us.
We will do our best to accommodate your needs and provide the best service possible.

1.9 About receiving the package
Whether you sign for the package personally or through a representative, it is considered as acceptance of the package, the quantity, and the included items.
To protect your rights, we strongly recommend recording a video while opening the package and verifying it against the order and packing list.

1.10 I don’t live in China. Can I have my order shipped to a Chinese address?
Yes, you can. Just place your order and provide a Chinese recipient address.
For orders shipped within China, we do not charge any shipping fees. If your item shows a shipping fee, please contact us to have the fee waived.

You are responsible for all applicable taxes and fees that may be imposed by your country or region, including but not limited to import duties, value-added tax (VAT), customs handling fees, and other similar charges.

These import duties, VAT, and customs fees are not included in our product prices or shipping charges.
We have no control over, and cannot predict, these charges or how they will be collected—whether they will be charged at the time of delivery or through other means.

Customs policies vary greatly by country. Some countries (such as Brazil, India, etc.) strictly enforce high duties and additional taxes.

It is your responsibility to check with your local customs office before purchase to determine what additional costs may apply.

Customs fees are usually charged by your local courier or postal service, often at the time of delivery or pick-up. The shipping carrier (especially UPS) may also charge brokerage or clearance fees for handling customs on your behalf. These are not unpaid shipping charges and must be fully covered by you.

If the package is returned, held, or destroyed due to the buyer’s refusal or failure to pay customs duties, any resulting costs will be borne entirely by the buyer. These costs will be deducted from your refund.

1.1 What is your return policy?

In the above cases, we accept returns within 30 days of receiving the item, provided that the product is in brand new and unused condition.

• Buyers must apply for a return and send the product back to us within 30 days of receipt.
• You are responsible for all return shipping costs.

If the returned item is damaged, missing parts, or shows excessive wear, we reserve the right to reject the return and no refund will be issued.
