I was wondering what people's experiences are with using the wider angle eyepieces with a fairly fast Newtonian and what they'd recommend? Currently looking to upgrade to a couple of very wide angle eyepieces to help with viewing DSOs and to make manually following objects like the smaller planets with our 10" dob a bit smoother compared to the current 7mm plossl we're using. As I understand it, the more budget 82 degree eyepieces will struggle vs a higher quality, lower FOV eyepiece due to the faster scope, but I was curious as to what the "minimum" (for lack of a better word) I should be looking at for an 82/100 degree eyepiece should be? I'm in the UK so any eyepieces available in the UK/Europe should be fine. Some of the series I was looking at would be SW Myriad, the ES 82/100 degree series, Meade series 5000 UWA and there also seems to be a series of 100-degree eyepieces that get sold under a few different brands, one of which is the TS XWA series. Looking at both a ~20-28mm and ~5-9mm EP to pair with a 2x barlow for a good range of magnification, and will probably be purchasing a coma corrector at some point. Are there any of these I should be looking at avoiding in particular? A small amount of aberration at the edges isn't really a huge issue as I'm not expecting perfectly sharp images across the whole field, just wanted to avoid the worst offenders on fast scopes so I know what to avoid and what to keep an eye out for second hand as well.
Hi All, About to buy my first real scope and mount. I'm wondering if I can put upon you good folks to ask for your recommendations for the items in the title that will match up with and compliment the equipment I'm about to buy. Top of my list at this moment is the SW EQ6 Pro with either the Explorer 250PDS or 200PDS (depending on the all the other items that need to get to at least make it usable fairly usable to start with and how that affect the overall budget). If I have to (for cost at this time), I will drop to a SW HEQ5 Pro with the 200PDS. Fortunately, my girlfriend/partner loves the night sky but I know she will want to see 'results' in the EP straight away and will want to mainly look at our Solar system and the Moon (not that I don't) but she hates the cold and has limited patience for waiting to see anything deeper than those for now. Myself, apart from the above of course, would like to go deeper but also include astrophotography once I have got myself up to a decent level of familiarity with the kit. I have a humble Pentax K20D DSLR and my very old Pentax Spotmatic F (Wet film) camera (It's been with me for a long time and still gets used once in a while). I would very much appreciate your collective wisdom regarding the title items and fitting my DSLR (primarily) to either of the two OTA's above. What is the minimum I need to get, make/models that will get me going and that will complement each other and the system without having to take out a second mortgage just yet ;-) and get me off to a fairly good start. I'm sure you have all had these questions before and I apologise if your first thought is "not again" :-) ... It's just that I have been lurking in the background of the site for a few weeks now reading up as much as I can and trying to pull a list together but my brain seems to have turned to fog now and after reading something earlier to day of EP's and Barlow's and that the optics in them (for want of a better word) should be in 'harmony with each other and the system, I've completely lost where I thought I was going and then also the subjects and threads that I had been using to 'guide' me elsewhere on SGL. Many thanks in anticipation. Kind regards, Chris.
Hello Gazers! I need some help ones again. Lets say I have a scope with a 150 diameter and a 1800 mm focal length.(f/12) I'll supplied with an 28mm eyepiece. I would like to know which lengths I should get? I'm in the market for PST pieces. These are the lengths they offer: 2x barlow 12mm 15mm 18mm 25mm 8mm 5mm 3,2mm All have a field of view of 60 degrees. In which order should I buy them? Clear skies:.)
