Telescope Focus Mask for Perfect Focus
Hello,the first rule for cheap telescopes that the magnifying must not be more 1,4D of telescopes. In your case it will equal 1,4*114=159.6Your telescope has 900mm of focus. So 900/160=5,6mm is maximum focus of eyepiece without barlow lens.
That is actually a great suggestion. Since I read your comment I was just trying to think when the last time I used my 4mm eyepiece and I cant remember. I usually only use my 20mm one and it works for everything and you don't have to have your eye basically touching the piece.To piggy back on that while talking about eyepieces, The barlow while it does increase the focal length of the telescope making your eyepiece double, triple, (I have seen 5X and likely more) in power (I really don't like that word mixed with telescope talk) I would never recommend using them more than 2X or most 3X with a eyepiece. These are often included with a telescope package because if they give you a 20mm, a 4mm and a 3X barlow its like they gave you a 20mm, 7mm, 4mm, 1.5mm eyepiece. But a barlow lens will often overpower the telescope and provide you with very dim and blurry images. Barlows are used often with astrophotography where dim and blurry images can be fixed in software.
I would consider also recommend: "use the low powers". Especially on inexpensive telescopes the high powers more or less suck, they seem to be put there so advertisements can promote them. Disadvantages of high powers include: low contrast, fuzzy images, small field of view, difficulty in finding objects, magnifies scope vibrations, and helps show image defects.
