  1. The triplet refractor will have better resolution than an Achromatic Doublet because all three colors, RGB, focus at a single point. You will be able to see more and finer details. I had a ES AR152 Achro and then got a 130mm APO. The color is much better and no fringing around bright objects. I can see more and finer detail also. I saw 3-4 light colored bands on Saturn that I could never see before!
  2. I have both the ES and Delos 14mm eyepieces. IMO they are just about a tie!! I like the 72° view of the Delos but performance wise they are very very close. The Delos may have a VERY SLIGHT edge in resolution. YMMV
  3. I went out the day after my observing session to the local astronomy shop and bought the 14mm Delos. Just like potato chips, you can't have just 1,2,3,4!!!!!!! So now I have 5 Delos and I thought I was all done with buying any more eyepieces, rightttttttt !
  4. Finally got a second light on my TS 130 F/7 APO last night. I've been waiting for 4 weeks for a decent night! We had very clear skies 2 nights ago but I had to work late and couldn't get out to observe. So yesterday was one of my days off and the skies were clear again. Setup the scope on my iEQ45 Pro mount about 9:45pm PDT. Saturn and Mars were both up about 30° to 40° above the horizon; so I did all my observing on these two planets. Seeing was very good for this area!! I also got to test my 4 new Delos eyepieces, 3.5mm, 6mm, 10mm, 17.3mm. The scope preformed excellently and the seeing was good enough to use the 3.5mm eyepiece, 260X. Mars was a decent size in the 3.5mm eyepiece. I could see Syrtis Major and Tyrrhenum on the planet. They were faint at times but when seeing settled down they showed very well. There was no false color/smearing color that I could see around the planet! I also spent about 1 hour observing Saturn. It's always a joy for me to observe Saturn!! The rings showed very well and the Cassini division was very prominent and easy to see. I could see a dark gray band about 2/3rds of the way up the planet. I could also see a couple of more faint color bands on Saturn. Saturn was more stable and seeing was better when I observed it. I also used the 3.5mm Delos on Saturn to great effect. Here again there was no false color anywhere on the planet. The detail and resolution of the scope was excellent. While the planets didn't snap into focus as quickly as in my ES102APO, it was still very easy to get them in focus. Everything worked without a hitch!!! Ok, on to the eyepieces!. I used all four of the Delos eyepieces (3.5mm-6mm-10mm-17.3mm) and the ES 4.7, 6.7mm, and 24mm (68°). I also used a Starguider 5mm eyepiece. The Delos were excellent in the TS 130mm scope. They gave me great views and I was able to see the dark details on Mars and the dark band and a couple of faint colored bands on Saturn. I compared the ES 4.7mm to the 3.5mm Delos and also to my 5mm Starguider eyepiece. The 3.5mm picked up the dark and faint bands on Saturn that the ES 4.7mm didn't see. The surprise of the night was the Starguider 5mm eyepiece. The Delos and the ES 4.7 were basically a tie on Mars and Saturn, with the exception of the 4.7 not seeing the dark band on Saturn. They were within 5% to 10% of each other in performance. The Starguider was nearly as good as both of the others. I was within 15% or less in performance of the other two eyepieces!! The Starguider did see the dark detail on Mars and just barely saw the dark belt on Saturn. The Paradigm/Starguider eyepieces are very underrated eyepieces! The TS 130mm was well worth the money and performance is excellent for the price. While it's not in the same class as Tak, Tec, or AP it performs extremely well IMO. I'm very happy with it!!
  5. I have two SCTs and two refractors. I would say get a 8" SCT for high power planetary and DSO use. The 8" SCT is the sweet spot for size, easy transport/setup, and big enough to see smaller faint fuzzies. Then get a 90mm - 102mm refractor from F/5 to F/7 for wide FOV use. That would pretty well cover the sky.
  6. I bought a C9.25 3 years ago. It was way out of collimation when I got it. I re-collimated it and have spent the last 1.5 years waiting for our skies to give me one clear evening (needed the moon in they sky to check my Moonlite focuser) to see if I did it correctly. We had several clear nights but I wound up being sick on those nights and was unable to get out and observe with it. Anyway got out a week ago for a about 11/4 hr and tried it out on the moon. It was fantastic and the collimation is excellent. I have wanted a C9.25 for over 20 years and could never afford one. Bought this one used and ended my quest. I had looked thru 5 C9.25 over the years and there views were always excellent. Mine seems to be holding up that tradition!! I put it on a iQE45 Pro mount and it handles it very well. The mount tracks great and is easy to use. The C9.25 is an excellent scope and light weight enough for most people to handle easily. If you get one I'm sure you won't be disappointed.
  7. Well I finally got 75 minutes with NO clouds to observe with my C9.25 scope and three of the Delos eyepieces and a few of my ES eyepieces. I had the Delos 6mm, 10mm, and 17.3mm eyepieces and the 11mm, 14mm, 16mm, 18mm, 20mm, and 24mm ES eyepieces out. The Moon was out and high in the sky so that was the target of choice. First off I love the "portal view" that people have commented on with the Delos eyepieces. The adjustable eyeguards are great and make using them very enjoyable. I didn't have time to get everything down to ambient temp but after the first 50 minutes the scope cooled down enough to give me some fairly steady views of the moon. The 6mm Delos was too much for the seeing so couldn't do much of a test with it. But the 10mm and 17.3mm did a great job with excellent contrast, sharpness, and resolution. My ES eyepieces held up just fine in comparison with the Delos. My opinion is that the Delos may have been very slightly sharper than the ES. But I'll need to try this again when I can get out and let everything cool down properly to make a final judgement call!! The 17.3mm Delos needed quite a bit more in focus that the other two. They also have a warmer tint, coffee colored is what some people say, than the ES. The ES have a colder tint, very stark very slight blueish/white tint. I bought the Delos mainly for my TS 130mm F/7 and ES 102mm F/7 refractors so I really want to do the next test in those scopes. Both of my SCTs are F/10 so nearly any decent eyepiece will look good thru them. But the Delos with be in my eyepiece case for a long while to come!!!
  8. I had a GSO 2" 2X barlow and it was surprisingly good for the price. I wound up giving it to my adult grandson with a C102GT refractor and a bunch of eyepieces and stuff. I bought the ES 2X focal extenders both the 1.25" and 2" models. The 1.25" fits my LS8 much better!! I really like their focal extenders a lot. Optically it was a better than the GSO but not tremendously better. They give me great views with no optical aberrations. Well worth the money to me.
  9. Another thing to consider is the faster the scope the better the eyepieces will need to be for visual use! That will put you in the upper price bracket for eyepieces. Lower cost and mid price range eyepieces work much better in slower scopes. At F/5 most medium priced eyepieces should work fairly well. At F/3.9 you'll be looking at top tier eyepieces and a Paracorr.
  10. Congrats on the new scope, looks great!! Looks like it will serve you well for a long time to come!!!!
  11. Use a piece of window/door screen and place it on top of the exit hole. It won't stop the hot air from exiting the scope but will stop the bugs from getting in.
  12. I use Lymax Cat Coolers for my LS8 and C9.25 SCTs. They cut the cool down times in half or less. Search on the internet for "telescope cat coolers" and you'll find a lot of articles on how to build your own using inexpensive PVC pipe and a computer 12v fan. I made one about 20 years ago and it worked just fine. When I got back into astronomy about 4 years ago I got lazy and bought the ready made Lymax, not cheap but they do the job very well.
  13. My new Delos 10mm got here today. Looks perfect to my eyes. No bits, dust, paint chips, etc. inside the eyepiece. Now if the weather would just give me one night of very good seeing I could see what the difference is between them and my ES eyepieces.
  14. Well, I now have 3 Delos eyepieces!! I ordered the 10mm Delos last night from Agena Astro and they shipped it this morning! I should have it Monday or Tuesday. I have NO self control when it comes to good eyepieces!!!!!!!!!! I need a 20 step program for my addiction to good eyepieces!!!!!!!!!!! Oh well, it's only money right!! I mean you can't take it with you. I told my adult kids I'm spending their inheritance.
  15. The focuser reduction drive is actually 10-1 not 11-1. My old eyes lie to me at times!!!
