The abbe index is the number used to quantify the "partial dispersion" of a specific glass. FPL glass features a partial dispersion that is so close to pure fluorite, which has the highest partial dispersion of any material at around 95 V, that it has been referred to as synthetic fluorite. FPL53 is top notch glass material that allows William Optics designers to achieve the best color correction.

It is also the most expensive glass on the current market. When you purchase a telescope from William Optics, you can be assured that your instrument was tested on their Interferometer.

Furthermore, each telescope is individually star tested by William Optics professionals to guarantee the ultimate in optical quality. Customers should communicate directly with the manufacturer regarding details of their warranty, as warranties have a tendency to change without notice. Lets Keep In Touch!

At High Point all in stock orders ship within 24 hours, pending internal credit card approval.I am often asked which telescope is best suited for the iOptron SkyGuider Pro camera mount. The SkyGuider is an entry-level astrophotography mount, which means that a lot of beginners start out with this piece of equipment.

Although this compact single-axis EQ mount is small and lightweight 3. The pound payload capacity is often the biggest factor considered when choosing a telescope for the SkyGuider Pro. This is a high performance imaging APO that uses high-end optical materials FPL in its objective lens to produce high contrast images with excellent color correction. The wide field of view mmcompact size, and optical performance of this little doublet make it the perfect companion to the SkyGuider Pro.

The SkyGuider is an incredible portable little astrophotography mount. Its compact size makes it a fantastic choice when traveling to darker skies. The SkyGuider Pro includes an internal, rechargeable 3. To charge this star tracker, you simply plug in the mini USB charging cable that you find with modern smartphones and electronic devices.

Once fully charged, this tracker will last for a full night of astrophotography in the field. The included ST-4 compatible guiding port is an attractive bonus of this mount, and a big differentiating factor between its younger sibling, the Sky Tracker Pro. This feature presents an opportunity for improved tracking, but also adds a layer of complexity, additional weight, and loss of portability. Without the use of an autoguiding system, you are completely free to roam around with this setup wherever the dark skies take you.

The SkyGuider was designed for portability and freedom, and I believe you will enjoy it most when keeping the payload and camera gear to a minimum. To retain the ultra-portable functionality of the SkyGuider Pro for deep sky astrophotography, it is wise to use a portable and lightweight telescope that falls well below the listed payload capacity of the SkyGuider Pro.

Weighing in at only 3. Although I have only personally used the SkyGuider Pro with the Z61 telescope and a number of camera lenses, I have researched a number of popular scenarios to help you make an informed decision.

The listed payload capacity of the iOptron SkyGuider Pro is 11 lbs 5 kg. Compare the overall weight of these popular telescope options with a DSLR camera attached:.

All of the telescopes in the chart above fall under the listed payload capacity of the mount, but will require accurate balance for the best results.

The extra reach focal length provided by a slightly larger refractor such as the Zenithstar 73 is tempting, but this option will demand that your imaging payload is precisely balanced. In the past I have used this combo to photograph deep-sky objects such as the Andromeda Galaxy, and the Heart Nebula.

William Optics Zenithstar 61 Review

The adorable Z61 only weighs 3. When calculating the payload capacity of your load, you need to remember to factor in the weight of your camera gear. So, a small refractor that weighs about 5 lbs or less falls well below the pound limit of SkyGuider Pro when the counterweight is used. A field flattener such as the Flat61 for the Zenithstar 61 is recommended when imaging with your refractor.

Luckily, this component adds very little extra weight. An autoguiding system, however, may put you over the limit. The Z61 is a high-quality doublet apochromatic refractor. A clip-in filter such as the Optolong L Pro is a smart choice for those looking to capture natural looking star colors while reducing the efforts of artificial lighting.

With a sound polar alignment, your images will be nice sharp using the Z61 for a 2-minute exposure. At this focal length, it is not essential to use autoguiding as long as your polar alignment and balance are precise. The focal length of the Zenithstar 61 is mm, which creates a useful field of view for many deep sky astrophotography objects. Also, this magnification is very forgiving in terms of tracking accuracy. Polar alignment and balance are the keys to a successful shot. When the mount does not need to work very hard to match the apparent rotation of the sky, your images will be razor sharp.

Use a remote shutter release cable or delay timer on your DSLR to avoid any camera shake caused by pressing the camera shutter.Zenithstar 61 is a greatly versatile and portable refractor telescope for beginners and veterans alike.

Designed for both astrophotography and wildlife photography, high power visual observing through the Zenithstar 61 Mark II is also hugely satisfying. The image is crisp, sharp and colour aberration free thanks to the use of top quality glass — FPL53, closely matching the legendary fluorite material. The 43mm image circle when Flat61 is used covers full frame size sensor nicely.

This APO is currently on loan from the manufacturer, but after a few imaging sessions — I think this may have to become a permanent member of my astrophotography equipment.

Aside from being a great portable option, The Z61 would make also great primary imaging refractor for anyone just starting out. The Z61 was mounted to an iOptron SkyGuider Pro Mount, and the camera was controlled using a remote shutter release cable. Choosing your first telescope to use for DSLR astrophotography can be a difficult process. A larger telescope may capture more light, but it will also be harder to manage, and much more demanding on your autoguiding and Polar alignment.

The Z61 is so compact and lightweight, I often set it up in the backyard for a spur of the moment imaging session using the iOptron SkyGuider Pro. The photo above was taken from my light-polluted backyard of the Heart Nebula. Please watch my video review of this capable little astrophotography telescope.

The color-matched dovetail plate included with my order has a beautiful gold finish.

You can tell the team at William Optics takes great pride in their products. The impressive optical quality of this apochromatic telescope is due to the FPL glass used. FPL is as close as you can get to pure fluorite, which means that your astrophotography images will display excellent color correction, with colorful, sharp stars.

This glass is used in the objective lens and is known as Synthetic Flourite. Once you get accustomed to astrophotography images of this quality, it is hard to switch from an ED refractor to other telescope designs.
