GSO 2" Dual Speed 10:1 Crayford Focuser for SCT Telescope w/ 1.25" Adapter

GSO 2" Dual Speed 10:1 Crayford Focuser for SCT Telescope w/ 1.25" Adapter



Many users find the primary mirror focusing mechanism of Schmidt-Cassegrain telescopes (SCT) cumbersome to use. There is some amount of image shift and precise focus cannot be found easily. This is inconvenient for visual use and a serious problem for astrophotography. GSO's (Guan Sheng Optical) latest Crayford focuser model is a gorgeous, all-black, rotatable focuser for Schmidt-Cassegrain telescopes that elegantly solves these problems.

CNC machined from aluminum and anodized black, this focuser will screw on to the rear cell of any SCT telescope sold by Meade and Celestron having a standard SCT thread. The standard SCT rear cell thread is an (approximately) 2-inch diameter male thread.

This dual-speed Crayford focuser is a joy to use and you will wonder how you ever lived without it once you install it! By design, SCT Crayford focusers eliminate the annoying backlash and image-shift that plagues many SCTs. You will experience very smooth and precisely controlled focuser motion.

The inner drawtube glides on 4 precision bearings and a roller shaft. The inner barrel is baffled and painted a flat black to minimize reflections for maximum contrast. This barrel is also black anodized and features a laser-etched mm (millimeter) scale.  It provides 1" of focus travel which is more than adequate for SCTs. You first use your SCTs focusing knob to achieve coarse focus and then switch to the Crayford focuser for finer focus and control. Depending on your range of eyepieces and accessories, you may never need to touch your SCT's main focuser again!

The 2" focuser barrel features a brass compression ring and can accept standard 2" refractor-type diagonals and other 2" accessories (Note that the use of this focuser converts your telescope's rear SCT thread to a 2" visual back. As a result you will not be able to use an SCT-type diagonal with this focuser; you will need a refractor-type diagonal instead). Also included is a 1.25"-2" adapter with brass compression rings and threads to accept standard 2" filters. This deluxe model features a 360-degree rotatable ring that allows you to orient the focuser (and hence your diagonal/eyepiece) to the most comfortable viewing position.

GSO's rated load capacity for their Crayford focusers is a little less than 6 lbs (2.7 kgs). The focuser also has two large thumbscrews. The thumbscrew on the telescope side can be used to lock the focuser, allowing the use of heavy accessories or cameras without fear or slippage or losing focus. The other thumbscrew on the eyepiece end can be used to adjust the tension of the focuser to achieve a focusing "feel" that you like.  At the easiest (lightest) setting, the focuser moves extremely smoothly. At tighter settings, you can still use heavier accessories without sacrificing much of the smooth focuser action.

Please note that some larger Meade and Celestron SCTs (11" and larger) have a larger 3.25" rear thread, so please make sure that you have an adapter that reduces that larger thread to the smaller 2" SCT thread. If you have a standard 1.25" SCT visual back, all you need to do is unscrew the visual back and screw on the SCT Crayford focuser in its place.  The focuser is shipped in a foam-fitted box.

Specifications:
• Minimum focuser height (with 1.25" adapter) = 4.29" (109mm)
• Maximum focuser height (with 1.25" adapter) = 5.28" (134mm)
• Minimum focuser height (without 1.25" adapter) = 3.90" (99mm)
• Maximum focuser height (without 1.25" adapter) = 4.88" (124mm)
• Tube travel = 0.99" (25mm)
• Focuser weight (with 1.25" adapter) = 1lb-10.5oz (751gm)
• Focus knob diameter = 1.57" (40mm)
• Microfocus knob diameter = 1.02" (26mm)
• Maximum outer barrel diameter = 3.3" (84mm)
-Thread: Standard SCT female thread
• Millimeter markings on focuser drawtube: Yes
• Rotatable: Yes
• Dust plug: One 1.25" dust plug included 

Please note: Most GSO Crayford focusers have or will soon develop two bearing marks/lines on the upper side of the drawtube. This is caused by wear on the barrel anodizing where is makes contact with the roller bearings. In some focusers, you have to look hard to find these marks. In others, it is very prominent, even for brand new items received from GSO. This does not indicate a defective or used product and is essentially just cosmetic.

Note: Occasionally, the product you receive might have a slightly different cosmetic appearance or labeling than what is shown. This can often change from batch to batch according to the whims of the manufacturer. However, you will always receive a brand new, original product as described above.

3. US SHIPPING

Delivery Time: Most orders ship within 1 business day of receiving payment. First Class shipments will take 3-5 days to arrive after we ship it. Priority Mail shipments will take 2-3 days. However, these delivery times are NOT guaranteed by the USPS. Delays of up to 2 weeks can occur in about 5% of the shipments.

Tracking/Delivery Confirmation: We will send you a Delivery Confirmation number in the shipment notification email after your order ships. This is not detailed tracking, but it provides some very basic tracking info en route. Sometimes, the USPS neglects to update this info for a few days but your shipment is not affected.

4. INTERNATIONAL ORDERING / SHIPPING

Shipping Cost: Click on the "Shipping and Payments" tab above and select your country to see your shipping choices and cost. If you need a shipping cost estimate for multiple items, please contact us.

Handling Fee: For all international orders, we charge an additional handling fee of 3% of the purchase price of the item(s). This will be added to your order total when you check out.

Delivery Time:

1) USPS First Class International: Delivery takes about 3-4 weeks after we ship your package. This can frequently take 4-6 weeks or more for several countries (8 weeks for Italy, Argentina, and South Africa; 8-12 weeks for Brazil). THERE IS NO TRACKING FOR FIRST CLASS SHIPMENTS. The information shown in your eBay account is just a customs form number - it is NOT a tracking number as incorrectly indicated by eBay. Once your package ships, we can do nothing but wait until your package arrives. Please do not become impatient and contact us in 2-3 weeks if your package has not arrived. If you don't receive the package in 6 weeks, contact us and we will work with you to resolve the issue. If you don't want to take the risk of this delay, then DO NOT USE First Class mail - use Priority or Express shipping instead.

(2) USPS Priority Mail International: Delivery takes 1 - 2 weeks after we ship your package. This can sometimes take 3-4 weeks to several countries. The USPS provides some basic tracking information for Priority shipping.

(3) USPS Express Mail International: Delivery usually takes 5-10 business days after we ship your package. You will receive a tracking number with which you can track your shipment from USPS.com. Note: If you use this option, you must send us your phone number when you check-out or else your shipment will be delayed. This is required for international postal forms.

Again, these delivery times are NOT guaranteed by the US Postal Service. The most common reason for delays is slow customs inspection and clearance in your country, and can be very long, even for Express mail packages. Upon shipping your order, delivery delays are beyond our control, so do not leave us negative feedback or file a Paypal claim if your package is delayed. Delays are quite common but losses are very rare, so your patience/cooperation will be greatly appreciated.

Customs and Duties: You are responsible for any duties and taxes that may be levied in your country. These are not included in the item price or shipping cost. We have no control over these charges and cannot predict what they may be or if they will be levied upon delivery. Customs policies vary widely from country to country (Some countries such as UK are strict about imposing hefty customs duties). It is your responsibility to check with your country's customs office to determine what these additional costs will be prior to bidding or buying. Customs fees are normally charged by the delivery company or your country's postal service, or collected when you pick the item up. These fees are NOT additional shipping charges.

5. RETURN/EXCHANGE POLICY

US Orders: We must receive any returns within 14 days from the time you receive it. A minimum restocking fee of 10% will be levied for all returns and exchanges. A larger amount will be deducted if there is evidence of use or wear, dirt, scratches, missing packaging/parts, etc. Shipping fees are non-refundable and you are responsible for all return shipping costs. Please contact us first before returning an item.

International Orders: No returns/exchanges accepted unless the item we shipped is defective. Please research the product and ask us any questions BEFORE you purchase to make sure you are buying the correct item for your needs.
