spacegalaxy Posted February 23 Share Posted February 23 (edited) I saw many videos of making eyepieces, and most were of making ramsden eyepieces, but then I saw this: And it literally blew my mind! Also this guy made another video which caught my attention: So, are these projects feasible? Are there any other eyepieces that I can make at home?

spacegalaxy Posted February 23 Author Share Posted February 23 Lens for plossl (Will these work?, He suggested them in the comments): https://www.amazon.in/Anand-traders-achromat-telescope-eyepiece/dp/B09716GG96 Also, I could not find a negative achromatic lens for cheap, so can anyone help me find one?

You could try: irpoyser.co.uk and see if he has one to suit. As he doesn't list everything he has got on his website you will need to email him.

Astrobits Posted February 24 Share Posted February 24 Go to 'home' on that page and you can then click on 'lenses' to see the options for ( mostly) positive lenses. At the bottom he mentions that he has more ( there might be some negative lenses amongst his stock) , just contact him with your requirements.

davidc135 Posted March 3 Share Posted March 3 (edited) spacegalaxy, Nice idea. You might find a 2nd hand Barlow cheaply and use its negative achromat. In removing the business end of a Celestron x2 Barlow and screwing it into the nose of a 7.5mm Plossl it amplified by x1.3.

Also, a bit of confusion, which Celestron Barlow do you mean? The cheap one or the Omni Barlow or some other one? Other than that, there are no doubts and once again thanks you!

davidc135 Posted March 4 Share Posted March 4 Well, they'd all work, I suppose the more pricey the better. I have a basic Celestron Barlow which does a good job but it may be that more expensive versions would prove their worth on faster scopes- mine tend to be slow. All Barlows contain negative achromats- or apochromats. David Link to comment Share on other sites More sharing options...
