  1. My barlow is the Celestron 93436 Luminous 2-Inch 2.5x. It's definitely not high end, but seems to be of good quality and has really given me some impressive views with the 12mm ES. I have no complaints with it. It's definitely a tall and heavy stack, but my focuser seems to handle it quite well. I haven't noticed any difference in terms of eye positioning, but I'm still kind of getting used to proper eye positioning in general (still a rookie!)
  2. Got it. Thanks. The 4.5mm option specifically brings up what I'm trying to understand conceptually... My 12mm paired with my 2.5x barlow gets me to 250x. A 4.5mm on its own gets me to 266x. Other than the small magnification increase, Is there any advantage to using a standalone eyepiece without a barlow? Does the barlow impact image quality in any way?
  3. I'd go up to $150ish... Seems like some of the midrange stuff I'm seeing (along with the StarGuider suggested above) are well below $100.
  4. Thanks. Any suggestions? I have a 30mm SuperView with a 68 degree FOV that came with the scope. I hardly ever use it anymore.
  5. Nope, but I'm open to all suggestions. I was intending to stick with ES since I was so happy with my two other eyepieces. Should this be at the top of my list? Thanks
  6. Hello All - I have an Apertura AD8 8" dob (1200 mm focal length) and am using the 12mm Explore Scientific 92 series and the 8.5mm Explore Scientific 82 series eyepieces. I'm very happy with both eyepieces and am considering a high magnification 3 or 4.5mm eyepiece in the 52 series from ES. My question is, should I even consider a 3 or 4.5mm eyepiece? My 8.5mm paired with my 2.5x barlow will get me solid magnification, but is there a situation where a 3 or 4.5mm on their own would do a much better job? I know I can't barlow them because my theoretical max magnification is 400x. Should I round out my collection, or is it not necessary? Thanks again!
  7. Thanks for the replies, guys. I figured an eyepiece in the 8mm range would give me a good high-magnification (non barlowed) option while also giving me the chance to barlow it under awesome conditions.
  8. Hello All - I have an Apertura AD8 8" dob (1200 mm focal length) which I'm now using a 12mm Explore Scientific 92 series eyepiece with. I'm very happy with the eyepiece and it even barlows well with my 2.5x Celestron barlow. I was looking into buying a smaller focal length eyepiece to have a couple options for my observation. I've read that magnification limits are 50x aperture, so I've been researching with the assumption that I can magnify up to 400x. My question is... If I want to use my barlow with my new eyepiece, am I still limited by this 400x number? I assume I am, so I'm looking at the 8mm range for a new eyepiece. So, the second part of my post... If anyone has recommendations for 8mm, I'd really appreciate it. Right now, I've narrowed down to the Explore Scientific 8.5mm LEF 82 Series and the Pentax 8.5mm XF Series. I think I'm leaning towards the ES piece since I'm so happy with my current one, and I saw a couple reviews saying that the Pentax isn't that great. I also came across the Baader/Orion 8mm, but saw that it's not a good eyepiece for faster scopes. Thanks again!
  9. Thanks for the collimation tip. I did it yesterday and it seems to look a lot better. My laser was pointing pretty far from center.
  10. Thanks for this... Definitely thought that my eye positioning could have been the biggest issue, so I'm practicing. It was better last night. Also collimated and that seemed to have helped a bit.
  11. Yep, that's it. It's mostly the elevation that doesn't seem fully rigid.
  12. Thanks, Steve. The scope is definitely moving, too. It won't fully lock. Maybe I just have to get used to this. The eyepieces are the included Apertura 1.5" 9mm Plossl and 2" 38mm 60 degree eyepieces.
