Explore Scientific ED102 102mm f/7 FCD100 Triplet Refractor TelescopePremium 4 inch triplet APO refractors from established brands typically start at $2,500 and climb quickly past $3,000. The Explore Scientific ED102 FCD100 puts genuine HOYA FCD100 triplet APO optics into a 4 inch aluminum tube at the lowest price point in its class, delivering the kind of star point precision and chromatic correction that serious visual observers and astrophotographers expect from glass at twice the price. Key Features HOYA FCD100

Premium 4-inch triplet APO refractors from established brands typically start at $2,500 and climb quickly past $3,000. The Explore Scientific ED102 FCD100 puts genuine HOYA FCD100 triplet APO optics into a 4-inch aluminum tube at the lowest price point in its class, delivering the kind of star-point precision and chromatic correction that serious visual observers and astrophotographers expect from glass at twice the price.


Key Features
  • HOYA FCD100 Extra-Low Dispersion Glass – FPL-53 equivalent optics virtually eliminate false color, delivering sharp, true-to-life views of planets, double stars, and deep-sky targets in both visual and imaging use
  • Air-Spaced Triplet Optical Design – Three-element configuration achieves 1.14 arcsecond resolution and diffraction-limited performance with high contrast across the field
  • Durable Aluminum Optical Tube – Classic white-finish aluminum construction provides a rigid, reliable platform that holds collimation well across varying environmental conditions
  • 2.5" Hexagonal Dual-Speed Focuser – Rock-solid rack-and-pinion design with 10:1 fine focus ratio supports up to 10 lbs of imaging gear with zero flex or image shift
  • EMD Enhanced Multi-Layer Coatings – Proprietary broadband coatings maximize light transmission and contrast for faint deep-sky targets
  • Versatile f/7 Focal Ratio – Long enough for high-magnification lunar and planetary detail, yet pairs well with a field flattener for sharp, flat-field deep-sky imaging
  • Retractable Dew Shield – Blocks stray light and slows dew formation during extended sessions
  • 99% Reflective 2" Diagonal Included – Premium dielectric diagonal maximizes light throughput right out of the box

Ideal For
  • Astrophotographers on mid-range mounts who want sharp, well-corrected APO optics that perform on a HEQ5, Celestron AVX, or similar payload without breaking the budget
  • Visual observers stepping up from doublets looking for clean, color-free views of planetary detail, tight double stars, and crisp star clusters
  • Dual-purpose setups — lightweight enough to piggyback on a larger telescope as a dedicated guide scope, separating guiding and imaging for superior long-exposure performance
  • Budget-conscious buyers who want genuine FCD100/FPL-53 triplet APO quality at the lowest price point available — this scope undercuts competing 4-inch triplets by $1,300 to $1,900

Accessories & Compatibility

Looking for the lightweight option? The ED102 FCD100 Carbon Fiber version shares the same optics and focuser in a carbon fiber tube that's 1.4 pounds lighter with superior thermal stability — ideal for portable setups and travel.

Note: A finder scope and carrying case are not included. The pre-installed 2N1 finder scope base accepts most standard finder scopes and guiding systems.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters. That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception. SPOILER: The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured. I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.

Good start to a series
Format: Kindle
I delayed reading the series for reasons I don’t remember. But my TBR list is huge so I thought I’d take a shot of this and I was pleasantly surprised. I didn’t think the blurb about it was anything special. But it was a very good book. It took some interesting twists and turns. I am so glad the second book is already out. Because I would not have waited patiently. Very slow burn but good storyline. 🔥🔥/5

A good read
Format: Kindle
Multiple points of view. 3 Alpha men and an Omega male. She is a Beta in training for a new program placing betas in Alpha/Omega packs. Mila is only doing the program for the money to take care of her dad. She wasn't expecting to fall for a pack but when she sees this packs Omega she is done for. There is just something about him. His Alphas are good looking as well. Too bad she is hiding a secret and their government is acting shady. I liked it and can't wait to see where their story goes.

Slightly repetitive but I did love some things
Format: Kindle
I love this type of story. And omegaverse is one of my all time favorite genres. But there are a few things that pulled me out of my enjoyment while I was reading. It was repetitive at times as well as struggled with telling not showing. So we didn’t always feel like we were experiencing things with the main character. There were also some plot holes but they may still be answered in part 2. Now this isn’t to be said I didn’t enjoy parts of the story. I loved the almost instant love between Mila and Oliver. And how he started changing around her.
