Thank you for all your answers. Gave me a sort of compendium.

Yes, but the contrast and background is important for me too.

I mean some eyepieces can cut weaker structures in DSO and the object becomes flat, homogeneous, and some eyepieces cut out weak objects completely and then in one eyepiece it is visible, in the other one not or in one directly, and in the other with averted vision. I have never had ethos or looked through them, unfortunately not my budget...

Thanks everyone...

Hello. Sorry for the title too long, but it was supposed to highlight the problem as well as possible I am thinking about eyepieces for dob f /4.5 - 4.8 that will best present the details of the DSO structure watched without cutting them out and for catching weak objects. So far I have had or watched through the following eyepieces, on different dob (about a dozen different dob from 5 to 20 inches, but not on every one I have tried every eyepiece): 1. I had ES 82 degrees 4.7; mm; 6.7mm; 8.8mm; 11mm; 14mm 2. I watched through ES 100 degrees 9mm; 14mm; 20mm, ES 30mm 82 degrees, ES 24mm 68 degrees 3. I had a LVW 8mm; 13mm; 22mm 4. I had a Nagler 9mm; 13mm 5. I watched through 7mm through Nagler; 20mm; 31mm 6. I had a Pentax XW 7mm 7. I had 23mm Luminos General impressions are: ES – flat, fuzzy stars, yellowish image, bright background, different sharpness in the center and on 20-30% of edges, clipping details and causing uniformity of viewed images, blurring details of structures and weaker faint stars in relation to the better eyepieces I used. I even prefer the 23mm Luminos than the 100 degrees 20mm ES. LVW - quite a dark image in small dob, but good point stars, a sterile image, I had them a long time ago so I remember it, but I compared them with ES 82 degrees and ES immediately rejected me with flat, fuzzy stars and yellowish image and a light background. Nagler - very good, point stars, a bit less sterile image than in the Pentax XW, Pentax XW 7mm I think it gave subtly clearer details of the structure in relation to the Nagler 7mm. Pentax XW - also excellent point stars, the most appealing to me was the way the image was presented, the cleanest and most sterile image and probably the best black background. I currently have a 12 inch f / 5 dob, but in the future I plan 14 f / 4.8 or maybe 16 f / 4.5. I am looking for two DSO eyepieces. 1. Eyepiece in the range of 8-10mm 2. Eyepiece in the range of 12-14mm The most important thing for me is that they don't cut off details in DSO objects and are as neutral as possible in the presentation of the image. I take into account: 1. Delos 10mm and 14mm 2. Pentax XW 10mm and maybe 14mm to check if FC will bother me and its scale 3. Delite 9mm and 13mm 4. Morpheus 9mm and 14mm 5. Something else... The combination of Pentax XW 10mm and Delos 14mm seems to me the best, but maybe Delite and Morpheus are equally good and do not cut the details, but cheaper and I could buy 3 pieces instead of 2 pieces. I have been reading for many days and it's hard to decide. Of course, it would be best to compare them all at the same time and conditions in person, but unfortunately this is impossible for me. What experience do you have in comparing the presentation of details of DSO object structures by the above eyepieces, and especially I care about comparisons on specific DSO objects ...
