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 115mm FPL-53 Apochromatic Refractor.

This is an all new design from Explore Scientific and offers greater quality optics provided by Ohara. We use Ohara FPL-53 glass in these optics which is very similar in characteristics as Hoya FCD-100.

Combining it with optical glass of high refractive index allows us to achieve unprecedented advanced chromatic aberration correction. Ohara FPL-53 is considered the best glass ever produced by Ohara. 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 Ohara FPL-53 extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.

In addition, this amazing scope also includes a 3" Hexagonal focuser with very rigid design and strong support. Up to 10 lbs of gear can be loaded onto this focuser.

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

A great program, even for beginners!

I have to admit, I was hesitant to invest in an “all in one” astrophotography program. Being a beginner, I thought the learning curve would be way too steep, but after talking with several friends I decided to give it a try. The first thing I noticed was the logical layout of the main screen. It was very intuitive and easy to navigate. Everything you could need for astrophotography is in this program! Setup of my equipment was quick and easy with no glitches or errors. Everything runs smoothly from capture to the final process. You will surely have questions and this brings me to the next point. Prism’s customer service is second to none! With on line tutorials, a Facebook group and email you will have instant access to knowledgeable users worldwide. My first question was answered directly by the US distributor within a matter of minuets! Take the next step and invest in your future in astrophotography! You’ll never look back!
