AusS2000 Posted June 3, 2020 Share Posted June 3, 2020 (edited) When I purchased my Celestron Evolution 6 I purchased the CELESTRON Optics Accessories AstroMaster Telescope Accessory Kit with it. Comes with a 6mm Plossl eyepiece. I find the 6mm very hard to use. I find it very hard to hold my eye in the correct place over the very small lens (6mm duh!) and my forehead often hits the OTA. And I just can't get a camera to work with it at all. Using a projection tube and Canon EOS doesn't seem to work and an iPhone mount over it never seems to be angled right. Are these just the standard peculiarites of using such a small lens? Or are there better options available?

happy-kat Posted June 3, 2020 Share Posted June 3, 2020 If you find you are having to 'waggle' head then keep an eye on what the exit pupil size is. I personally find 1mm quite hard and prefer to stick nearer to 2mm or above. Link to comment Share on other sites More sharing options...
happy-kat Posted June 3, 2020 Share Posted June 3, 2020 Your exit pupil with a 6mm eyepiece is .6mm with that telescope I think Link to comment Share on other sites More sharing options...
michael.h.f.wilkinson Posted June 3, 2020 Share Posted June 3, 2020 It is not just the small exit pupil, it is the short eye relief. I use a 6mm Delos on my C8 when the seeing is really good, and that has a generous 20 mm eye relief, which makes finding the right spot much easier.

Alan White Posted June 3, 2020 Share Posted June 3, 2020 I think it is a mixture of inexperience and the tight eye relief, when I started I had similar eyepieces and struggled, bought differing designs and was ok until I found I was observing more than just looking..... then I learned to use short eye relief eyepieces and enjoy them very much indeed. Its a journey, no simple single one but an ongoing one, learning every time. Link to comment Share on other sites More sharing options...
bomberbaz Posted June 3, 2020 Share Posted June 3, 2020 I don't get one with plossl's either. Are you wearing glasses to view? It's near impossible to do so with a 6mm plossl and make it an enjoyable experience. Anyway, as mentioned about the lack of eye relief in them does nothing to help either with or without. A good option at not budget breaking is an eyepiece with decent eye relief, these X-Cel are worth considering. I have used these in a C8 before and found the views both easy to achieve and very good.

bingevader Posted June 3, 2020 Share Posted June 3, 2020 I have an 8mm plossl and that's plenty low enough for me! If you want a replacement for the 6mm that is a reasonable price, then I can highly recommend the WO SPL 6mm. 1 Link to comment Share on other sites More sharing options...
AusS2000 Posted June 4, 2020 Author Share Posted June 4, 2020 (edited) I have ordered a Orion 8885 5mm Edge On Planetary Eyepiece. Has 20mm eye relief. Edited June 4, 2020 by AusS2000 Link to comment Share on other sites More sharing options...
