Hello, this is my first post here! I'm a beginner astronomer and my main interest is viewing DSOs (nebula, clusters, etc.) and plantets. Astrophotography is not my thing. My observation site is on a Green to Blue zone, usually with clear skies but regular seeing conditions due to high atmospheric turbulance and dust.
I recently purchased an Orion XT12 intelliscope Dobsonian. 12" aperture, F4.9. It came with 2 regular Plossl EPs: 10mm and 25mm, that gives me 150x and 60x magnification respectively. Those are good enough, however as with any stock EPs, I quickly grew past them.
I'm planning on improving my EPs to match my telescope and at the same time increase my range of magnifications, so I wanted some recommendations from the awesome community here.
I have one important consideration: budget. Since I live in Brazil, everything I buy is massively more costly, so expensive EPs (say, more than $200) are out of question. I'm planning on expending no more than $600 (which would translate to more than 3000 BRL, 6000 with taxes). So I need to optimize my EPs. Another important consideration is that I have a fast telescope (f4.9) and from what I've read, those types of telescope can be quite sensitive to EP aberrations. That said, since I'm limiting my budget, I think I won't buy a coma corrector, since those are usually very expensive (the good ones, at least). In short, I need good midrange EPs that fare well in a fast telescope.
After much researching, my idea now is to buy two ES 68° EPs: 24mm and 16mm, and a 2x FE/barlow from ES. I've read great things about those EPs and the FE, and it seems to me that they fare relatively well in fast telescopes, even without a coma corrector. I would also get a good range of maginification: 62x, 93x, 125x and 187x. I would also have 150x and 300x if I include my 10mm Plossl.
What do you think? Is this a good idea? I'm also open to other suggestions, of course!
