Re: Creating a basic set of eyepieces for your new telescope
True, we like to nerd about EPs (and other equipment to), but we are talking about technology and how you would explain technology without getting technical? Oversimplifying it not good either. The worse advice you can look for is I used thatMike Q wrote: ↑Thu Jul 13, 2023 9:02 am I see this all the time.

Re: Creating a basic set of eyepieces for your new telescope
Mike, the Sky Searchers is not your typical Outreach audience. We run the full gamut of experience levels here. So, to limit oneself by not talking about all aspects of the exit pupil does not serve the broader readership who regularly frequents these forums. A large percentage of our readership wants to know this information. Those who don't want to know this information can stop reading whenever they choose. Why would you limit knowledge for fear of glazing over someone's eyes, sounds a bit myopic.Mike Q wrote: ↑Thu Jul 13, 2023 10:37 pm When I get questions at outreach I explain it in very simple language based on my experience. Then i let them look and decide for themselves. The KISS theory is in full effect. I take it just far enough to see the light bulb come on and thats it. I can explain the scope and its tech without sounding techy. I keep it simple stupid lol

Re: Creating a basic set of eyepieces for your new telescope
This article was made for the first time user and shows them how the telescope and eyepiece relate to each other in a basic manner and gets them a basic set that will work with their telescope. 5 minutes with a pencil and paper = saved €€ on a small budget.
For the well experienced observer or those that are not interested in the technical side, this article will likely not have much for them.
If you are a beginner it will prevent you from purchasing a 65 mm Russell Optics Konig for their 200 mm

Re: Creating a basic set of eyepieces for your new telescope
If you don't care about matching eyepieces to optical tubes then don't read it.
But don't stop or criticise those who do want to match appropriate eyepieces to optics. Understanding/matching exit pupil to entrance pupil is important to maximising light transmission. Matching the shape of the telescopes focal plane to that of the eyepiece is also important. That's why some eyepieces work beautifully in an f10
In 2020, I wrote this observing report that tested and explained the effect of poor matching of exit pupil to pupil dilation.
https://theskysearchers.com/viewtopic.p ... 54#p149861
My primary advice to new telescope buyers would be to set aside 1/3 to 1/2 the budget for 1 or 2 decent eyepieces well matched to the primary optic.
