Hi folks! I could you some insight, thoughts, suggestions, guidance.
I have an ES 127 ED FCD100 and so far, I'm really enjoying it and am in the process of building up my knowledge/tech to do DSLR AP. I know that with a refractor I need at least a field flattener to deal with any of the wonkiness of stars around the edges of the image. However, I'm curious if I should also invest in a flattener/focal reducer combo? I've read a lot a but what a focal reducer does, which makes sense, but I haven't really read much about the value that it brings. I'd love to hear from folks experiences that use a flattener/reducer. What does it do for you that a you couldn't do otherwise? Does it help improve image quality at all? Does it make it easier to cut out some exposure time?
ES has a big sale going on, till the end of the month and I have thought about getting this one, but maybe just the flattener is all that I really need? I was looking at it because it's on sale and also because ES is going up on their prices across the board starting 10/1 and the new cost will be $450 USD. Is this one worth it? Are there other models/brads that would also work with my 127 ED? I reallllly don't want to spend more than $350 as my set budget if possible.
Any guidance or help is always great. Thanks in advance!
