  1. Sorry for the very very late response, I've not been on this forum the past 3 years. In the end I ended up getting a ZWO asi 1600mm-c with LRGB and Narrowband filters which I'm still rocking. Together with a takahashi FS-60CB (still need to work out some spacing issues because takahashi doesn't like off brand adapters) The Sony hasn't seen light since 2015 I think, has since been replaced with a Nikon D750 and 24-70 F2.8 Tamron. An adapter is underway to get the ZWO on the Nikon lens.
  2. I have set my focus on the Skywatcher Esprit 100 with field flattener, seeing some really nice reviews on it. The TS scopes have some bad ones and i am not willing to part on 2500 euro's on a scope I am not sure will do the job perfectly. Besides it would save me almost 300 pounds so part of that will go up to a filter set for the upcoming ASI1600MM or a feathertouch to slap on that Skywatcher! I am just not that keen on buying something online with the chance of not having a physical store to go back to in case of troubles. I could also pass enough money on a 120 Esprit but being F7 its quite slow. Have heard some people using a APM 0.75 reducer with it but not sure. The skywatcher will be my final choice im thinking, the imaging circle on that will be big enough since I dont see myself getting a full frame CCD in the near 10-20 years. If I do decide on full frame camera's ill grab myself an FSQ106 whenever that time might come. Thanks for the info!!! wish me luck in keeping all the money I earn saving for that beast. A young man sometimes has to party .
  3. The 100Q isn't a 6 element one, it's a petzval Quadruplet. They don't have any spacing problems, it's just focus and go!.(I fully read your woes and all about the spacing problems) I have indeed thought of the TS photoline setup with a riccardi-reducer. They look pretty neat but also, since I have such bad experience with separate reducers I feel a bit iffy about getting a separate one and having the same issues I have now. The CFF telescopes do indeed look very nice and I have had my eye on them but they do indeed stretch my budget to a new high. I can unfortunately not stretch it that far.
  4. Thanks for the input both, I have figured out it is in fact the flattener which is probably also the reason giving me the bad stars, there is no slop in the focusser as checked with a cheshire and a center mark on the front element. This won't be a huge problem for long, going to give myself a nice Christmas present in the form of a 100mm Quadruplet from Stellarvue. I will use the ES on top of the Stellarvue to guide it. Guess the ASI will have a nice and fancy triplet APO to look through
  5. Hello all, I've been looking at some upgrade for my small 80/480mm Explore scientific. I've been looking around for a 4" Quadruplet or 4" triplet. I know about the takahashi's but I'm really looking forward to an upgrade in both aperture and focal length. 600m range. So far I've found a couple of options: TSAPO100Q. Nice aperture, good looking piece of kit and the few reviews around are very positive. It has option to later move on to a full frame CCD or DSLR because of its 49mm imaging circle. TeleVue TV-85. Unfortunately almost same aperture. With reducer a quick scope with ofcoarse the TeleVue quality. A little too expensive. Skywatcher Esprit 100mm with flattener. Still has the same problem as now with my ES, a separate flattener. Williams optics Star71. I've heard only good things about it but unfortunately only 71mm aperture so lose the visual ability. Large 130mm Robtics (same as TS) with 3" reducer/flattener. Never heard anything about these scopes at all. Borg 90FL fluorite 6 element astrophotography set at F/4! Very quick but also a downside because of its F number? Also very short focal length which I'm slightly trying to increase. I'm still very confused about what to get, so far I'm setting my bets on the 100 Quad of TS because it ticks all the boxes however I hope someome can enlighten me on what would be the other best decision or give me some notes on why not to go with the Quad from TS. I'm open for suggestions but my budget will max out at 2000 pounds or 2600 euro's. Thanks in advance, Clear skies. Buikimaging
  6. Hello all, I kept having bad stars and after finally having a light in my brain switched on after, you read it right, 7 MONTHS! I decided to check any focusser tilt, using my ASI120mm and a self centering adapter this came out. As you can see.... I dont even know how to explain it, but its INCREDIBLY far off. this is an image where i tilted the focusser as far as I could and i could still not centre the image of the front lens to the crosshairs. I know the sensor of the ASI could not be squared itself but by this amount??? I also notice how its tilted to the upper right, the same spot where my stars are good using a DSLR. The lower left, upper left and lower right corners is where the stars have bad shapes with my DSLR too which makes me think the focusser is way out of alligment with the tube. I know of tilt adapters but I use a DSLR so that would interfere with the backfocus distance soooooo.... Anyone have any idea's? Clear Skies, Buikimaging PS: it's a Explore Scientific 80ED triplet. old version, not the hex-focuser.
  7. Yep in the settings you have to turn off AR mode. Then you can slide around on the chart. Dont use automatic or on if you want to stay on target.
  8. These are some test pictures of the asi 1600 mm cooled. I'm impressed so far. Photos from beta testers. https://astronomy-imaging-camera.com/gallery/ I'll wait until there are more test result images.
  9. Star Chart the best there is. https://play.google.com/store/apps/details?id=com.escapistgames.starchart&hl=nl
  10. I have already checked spacing from everything ranging from 55-61mm, nothing seem to be working, the focusser is squared to the center of the OTA, nothing wrong with the focusser and can hold the camera easily. Once I change the spacing the stars will basically turn into "crosses". Added images are the edges of my frame, its also not equally devided in each corner, one seems worse than the other.
  11. Hello all, I'm looking to upgrade my kit sooner rather than later as I hate the horrible shaped stars I'm getting with a cheapo field flattener. I hate the cropping i have to do and want to do nice and wide field views. I've looked at different flatteners however i cant seem to get my head around some things so advice wanted! The explore scientific 80/480 ED is a great scope, however i am leaning more and more towards astrophotography so the question would be: 1. Get a way better flattener: TeleVue TRF-2008 or dedicated 3" Explore Scientific 0.7X reducer/flattener. OR 2. Trade the Explore Scientific 80/480 in for a dedicated quadruplet like the Primalucelab Airy 65 or Williams Optics GTF81. Both will get in the same price range. There is nothing wrong with an upgraded reducer/flattener however im thinking the dedicated reducer in both those scopes will do much better than a seperate reducer/flattener on the Explore Scientific. I dont mind cropping out, say the outer rim to keep some of the bad stars away off an APC-S sensor but the one I currently use needs at least 50% in order to get at least some good stars. So feel free to comment, Upgrade or Replace? Clear Skies, Buikimaging
  12. That's exactly what I'm also doing amazing barlow by the way! Took this image that night through murky clouds with an ASI120MM, but back to the Delites, might be good to get some extra zoom in the future ofcoarse
  13. Thanks both, I am definetely thinking of getting more of the DeLite range, maybe a short focal length for the extra magnification on the moon or something similar. I will add some more of the review as I do some deep-sky work with both the ED and the newton, but I can't imagine it failing at that considering the amazing views it already gave.
  14. Hello all, As a starter I would like to let everybody know that i am not an extremely experienced observer thus my statements and opinions might not be correct and are subjective. The DeLite range are a relatively new line in the TeleVue brand and I am going to review it in combination with the TeleVue 2X barlow. The DeLite is a small brother of the Delos range and features the great 20mm eye relief of the Delos but has a smaller AFOV of only 62°. Telescopes used: Skywatcher 250PDS and Explore Scientific 80ED Triplet. DeLite The unboxing. As can be expected with any quality eyepiece, the DeLite came in a very sturdy box, much better than some of the "carboard/paper" boxes. It feels as this wouldn't get saggy or tear like the carboard boxes will. The eyepiece box contained some documentation and instructions on how to use the eyepiece. The eyepiece itself was nicely wrapped in 2 pieces of bubblewrap and a plastic cover around the eyepiece. Build Quality. The eyepiece feels of very good quality with a nice chrome barrel, the beautiful TeleVue DeLite markings. There was no damage what so ever on the eyepiece casing, not a single scratch. The eyepiece protections caps feel nice and sturdy and have TeleVue printed on both of them. Slight remark towards the plastic protection caps. They fit nice and tight, a little too tight for the bottom one which, when not pulled down straight, would cause the chrome barrel to unscrew. Not a huge issue but something to note. A nice design feature is the ability to change the height of the eyeguard housing and its ability to lock it, the action feels very smooth and once locked feels really sturdy and i wouldn't see it moving by accident. The lenses appear pristine with no markings visible, the coatings appear purple in reflections. The top eyepiece glass has a small indentation which is belongs to this eyepiece, I have no experience with any of the other DeLite range so i can not exactly tell if this is only on the 18.2mm. As I do not own any 1¼" filters I can not see how the filter threading on the eyepiece barrel is but it looks good. Optics. During the first test using the 80ED triplet I tried some dusk lunar observations with the sun still shining quite bright. First thing I noted was the very nice color reproduction. It did not feel like I was looking through a telescope at all and the moon seemed color free. In focus the detail on the moon was revealed very nicely. Even on this low magnification it was a great sight to see and a good half hour went by before I took my eye of the eyeguard. There was no color on the edge detected what so ever and it looked very fine and sharp. Taking a look at the field stop showed it was razor sharp with a hint of a blue rim around the outer most edge near the field stop itself. I found this minimal and it is barely noticeable. After sunset we used the eyepiece in the Skywatcher 250PDS. A rough alignment on Jupiter later revieled it and its moons in pristine quality. The details on Jupiter looked amazing, the red spot was easily spotted and some of the smaller storms were even visible at this magnification. It was a beauty to behold and again the eyepiece did not show any color and views were very nice even right up on the edge of the field stop. We moved on to the moon to show some more detail than the ES80 ED and we were not surprised to see some very nice detail. The lower craters were nicely defined and the Terminator looked very nice revealing the tiniest of craters. Hopping over to some stars, just before the clouds set in. The image was nice and clear, seeming to look much cleaner and brighter than the Maxvision 24mm 68°. Stars were looking like pinpricks over the entire field and the double star Mizar and Alcor looked fantastic. Shortly after we had to pack everything up due to high clouds. Conclusion. We are very impressed with the eyepiece, really good optics, really good build quality and appearance. I can highly recommend this eyepiece who wants TeleVue quality but does not have the money for the Naglers or Ethos or Delos eyepieces. I hope this was of some help to the people trying to decide if they should get these or not. They are of fantastic quality and in combination with the barlow gave me very impressive results of Jupiter, showing the color of the red spot easily and giving me detail I have no even seen in a Meade 12" ACF and Delos eyepieces at my local astronomy club! Feel free to leave any questions in the reactions! Clear skies, Buikimaging.
  15. Try Hubble Hi res in Google. The most stuning picture you could wish for. Or do you need a amateur made picture.
