In episode 530 of The Actual Astronomy Podcast, hosts Chris and Shane reveal a major upcoming guest: David Nagler, president of TeleVue Optics, who will join them in June to discuss eyepiece selection and visual astronomy. The episode is framed around a listener-driven Q&A initiative, with a May 24th deadline for astronomy enthusiasts to submit questions about eyepieces, TeleVue gear, and observational techniques. Chris shares his nervous excitement about speaking with Nagler—whose name is synonymous with high-performance wide-field eyepieces—and highlights Nagler’s deep commitment to helping amateur astronomers make informed choices, avoiding 'paralysis by analysis.' The hosts also dive into personal gear updates, including Chris’s new Skywatcher power adapter, a second Antares 1.25-to-2-inch adapter, and a new Blossel occulting eyepiece from listener Alistair. Shane discusses his experience with Zeiss 8×30 SFL binoculars and a new pie finder firmware update with sky quality metering and a double star database. A highlight is Chris’s project to convert his old 12.3-inch Newtonian mirror into an ultralight scope, built by a listener hobbyist—part of a growing community of amateur telescope makers. The episode closes with a heartfelt thank-you to the listener who designed 3D-printed rings to improve telescope balance, underscoring the podcast’s spirit of collaboration and innovation.
Submit eyepiece questions to actualastronomy@gmail.com by May 24th for David Nagler of TeleVue Optics to answer on a June episode.
TeleVue eyepieces are renowned for 99.99% light transmission and a unique balance of wide field of view and optical clarity.
David Nagler prioritizes helping amateur astronomers choose the right eyepiece through personalized guidance, not just product promotion.
The pie finder now features a sky quality meter and a database of 300,000+ double stars via a recent open-source firmware update.
A listener-built ultralight 12.3-inch Newtonian telescope is being constructed from Chris’s old mirror, with a focus on portability and ease of setup.

Announcing David Nagler of TeleVue Optics
“He was very direct with me about the fact that if this didn't totally sync up with our podcast, he wasn't doing it.”
TeleVue’s Legacy and Eyepiece Innovation
The hosts reflect on TeleVue’s history of pioneering wide-field eyepieces, including the 80° Naglers, 100° Ethos, and the recent long-eye-relief models, emphasizing their unmatched light throughput and build quality.
Listener Q&A Initiative for David Nagler
“I have been thinking about a couple different TeleVue eyepieces. Maybe if there's time... I might just call him and be like, all right, these are the two I've been wavering on. Which one should I get?”
Personal Gear Updates and Observing Challenges
Shane shares his new Zeiss 8×30 SFL binoculars and discusses poor observing conditions due to extreme cold and freezing rain, while Chris reflects on his lack of recent observing.
Power Adapter and Accessory Upgrades
Chris reviews his new Skywatcher power adapter, praising its robust build, single-piece cable, and proper red LED lighting, which solved recurring disconnection issues with generic adapters.
“He was very direct with me about the fact that if this didn't totally sync up with our podcast, he wasn't doing it.”
“It's just kind of weird. Like it sure would be nice to have that in like a wide field eyepiece. Like, yeah, it's fine in the plossal. We'll see how useful it is. But it would be nice to do that in like a 70 or an 80 degree eyepiece.”
“I'm really excited to see this project completed and look through an ultralight 12”
