Description

Reveal celestial wonders like the desolate beauty of the lunar terrain, the serene structure of Saturn’s rings or the brightest deep sky treasures of the Messier catalog with Explore Scientific’s 80mm FCD100 Apochromatic Refractor.

This is essentially the same scope as the ES-ED0806–01 but offering greater quality optics. We use Hoya FCD100 optics which is very similar in characteristics as Ohara FPL-53. Relying on technological innovation, we have successfully launched the mass production of high-performance optical glass at the apex of the FCD family. Combining it with optical glass of high refractive index allows us to achieve unprecedented advanced chromatic aberration correction. Hoya FCD100 is considered the best glass ever produced by Hoya.

Having a true diffraction-limited optical design and sized to encourage spontaneous stargazing sessions, this high-quality telescope is a perfect grab-and-go instrument for exploring the skies.

Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA FCD100 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.

In addition, this amazing little scope also includes a 2.5" Hexagonal focuser with very rigid design and strong support. Up to 10 lbs of gear can be loaded onto this focuser.

Although it is a standout telescope on its own, the 80mm also is compact enough to mount on a larger telescope, which can add versatility to your astrophotography experience by separating the guiding and imaging duties. The telescope tube's outside diameter is 91 mm.

ED80 Classic White f/6 Air Spaced Triplet with Hoya FCD100 optics and Integrated Dew Shield; 480mm focal length; 2.5" HEX Focuser; Integrated Vixen-Style Dovetail, Explore Finder Scope Base installed on scope; 99% Reflective 2" Diagonal. Weighs 7.5lbs. (Case and Finder Scope NOT Included)

Exceptional Mount

A couple of years ago, I wanted to replace my old VMA200 mount with something more modern.
While visiting the Paris Astronomy show (RCE 2012) I noticed the Nova120. At that time, it was a brand new offering that I have not seen before, hence my hesitation to purchase
I wanted to purchase a E.U product to guarantee the quality and ease of access to support in my own language. I checked the forums and heard nothing but good things about the Nova120 so I decided to purchase it.

I have used enough astronomical instruments in the last 30 years to know what great quality is. The Nova120 coupled with the PRISM v10 and a CDK20 (508 mm) helped me pull off 900s unguided images with great ease. (Raw FITS File here). Payload of this setup is about 80 kg (160 lb).

The dizzying slew speeds, excellent accuracy and painless tracking makes this hobby easy and enjoyable again.
After using this setup for a year and a half, the only problem I had was rebalacing the gear after changing scopes. The superb electronics and software included make this tasks even more easier that just eyeballing the scope for movement due to unbalance.

You can very easily watch the motor consumption and know where the unbalance is....that easy. I have so much data that it is becoming difficult yo keep up.
I have absolutely zero regrets, this purchase has made everything easier: No summer/winter worm-gear adjustments, no guiding... just start imaging night after night after night.

Imaging Made Easy

Prism is my GoTo program for observatory control and imaging. Prism's many features make imaging taking a breeze.

I was concerned about giving Prism a try , especially as its quite expensive. So far Im very impressed and glad of my decision.
Im a beginner at all this so haven't tried other more recommended software, Prism appealed as it seems to do everything instead of using several programs 👍🏻

Great lightweight guide scope

This guide scope replaces a 400/80 that was waaay too heavy for what it did. The smaller 60mm scope does a great job guiding and I can RA balance with just one counter weight now - much better - and it looks like something Ferrari designed

Still learning Prism using Wireless links...

I have much of your software working at this time... I have it parked on my main computer, and a notebook... My main computer is a OverClock computer with 32 Gigs of RAM Clocking presently at 4400MHz with software parked on SSD drives... The rotation dome by NexDome is still not working... Most problems like this have to do with ASCOM Drivers... There is not very much detail information on how to use this software... I have to feel my way to a total operational staus... Second issue... The rain in the San Francisco Bay Area this year has limited my access to my larger telescope (12 inch SCT)... This rain has been so significant, I was force to weatherize my observatory... My goal here is,,, I am trying to remotely control my observatory totally. I have used Netgear Powerline 2000 to handle camera images and discover controlling rules to do that... High speed is vital for images with cameras over 3 Megs... I have both 12 Mega sensors and 24 Mega sensors... I am also using Netgear Nighthawk router and its mating extender to increase control signals to my observatory that is about 100 feet on the side of hill... I am also using Virtual Here software on a Raspberry Pi inside the observatory to solve the USB interface requirements... I started out using Model B and B+ on level 3 raspberry Pi's... I have moved to Level 4 Raspberry Pi to gain access to USB 3.0 technology... Big difference! I hope by early spring to have everything working... Bob Ritter MicTechS
