Regarding this point, my understanding is, I could use: 25mm @ 60º = 1.3º True FoV - 48x magnification 32mm @ 50º = 1.3º True FoV - 37x magnification 40mm @ 42º = 1.4º True FoV - 30x magnification Since the true FoV is the same (roughly) for all of them and is the greatest allowable for the 1.25" focuser, what are the better objects to view with each option? Assuming the optic quality, eye relief, etc. all were equal?
Hello, I'm just getting starting in the hobby and would like some advice. I've done a fair amount of research already here and other sites, but it's a bit of information overload. I just received an Orion XT6 (1200mm f/8) as a gift(!) with the standard 25MM eyepiece. I live in NE USA (~43N latitude) and from behind my house have a pretty good clean view S to WSW about 15/20 degrees and higher. This is where I intend on doing most of my viewing, but I can go out in the front, and see a lot of the north as well. I live in a suburban neighborhood with no streetlamps, but most houses around have modest porch/backdeck lights on at night. My intention is to see "cool things" At first, the moon, planets, (sun?) and then go from there. I have kids age 8 and under, and I'd love to engage them on this and once I know what I'm doing, any neighbor-kids as well (mostly ages 11 and under). First night out, we found Jupiter and through the 25MM (48x magnification), I saw a small round object, slightly reddish in color if you really stared at it, with a beige-ish band around the middle, then the 4 objects which looked like stars, but were all in a row, so must have been the moons of Jupiter. It was also nearly a full moon, which was fascinating, but also a little blinding without any filters, so I will be getting a filter. Second night out, we pointed north, and viewed some stars, but without any visible planets or moon, we mostly wandered about. Tried to find Uranus and Neptune but either was not able to, or we did, but they did not look any different then stars with the equipment we had. Anyway, I'm looking for some advice/direction for what to look for in the sky, and what eyepieces to upgrade to (to a set of 4-5 eventually). I figure it would be better to buy one higher quality eyepiece at a time, than a complete set of cheaper ones. My target price-range is ~$50-90 USD range per eyepiece, but I'd likely only buy one per 6-12 months, so I'd a variety set, but like to get a lot out of the first piece in particular. I have no problem with buying something used (if I can find it used). I was thinking of purchasing in the following order over the next few years: ~6.5-7MM (171-185x mag) - From what I understand, this is the going to be the highest magnification that is versatile enough for most seeing conditions. >82 FoV would be better, but 60-62 deg FoV would probably be ok if the optics are noticibly better than the wider FoV in my price range (for example Meade Series 5000 1.25" HD-60 deg FoV 6.5MM better than Celstron Luminos 7MM 82 deg FoV?) ~11MM (109x mag) - With a 82 deg FoV, full view of the moon/sun taking up most of the view. ~32MM (38x mag) - for wider surveys across the sky Barlow 2x - Double the 11MM for 218x for more magnification on planets during optimal seeing conditions, and double the 32mm for 76x mag. Summarizing my questions: Are my assumptions correct about magnification limits /seeing conditions my scope and environment? What general limitations are considerations for eyepiece for my scope? What are some specific suggestions for brand/model of new 1.25" eyepiece(s) for my scope in my price range? Used is OK, if I can find it used. Should I aim for a ~7MM or the 11MM first? Or something else altogether? Solar filter suggestion? What are some good targets for the specific scope/25MM eyepiece I have right now, from my current location over the rest of October/November of this year? Thanks in advance!
