  1. Hello, Hello, I am considering buying a small refractor ED or APO lens for wide field observations (not to use it as a big magnification telescope), for those nights that there is not much time and that with the Maksutov I have to wait for it to cool, rather to take a quick look at the Moon, or some clusters of stars,and regions with nebulae as for example in the summer Milky Way..but also to use it as a spotting scope for terrestrial use and birdwatching .. (logically with good weather), I know that there are some very expensive (for my budget) as the Televue or the Takahashi ... these are out of my pocket, I have seen that there is the refractor TS Photoline FPL-53 60mm / F6 , and also the refractor TS ED70 / 420 (INED ED70) that I think has FPL-51.; I would like to know your opinion about these two small refractors, or if you know some other interesting modesl .. In your opinion in these sizes is best 60mm or 70mm? I believe that an 80mm is already too big for what I want it .. The better lens FPL-53 worth , or the FPL-51 is plenty of satisfaction for visual image? Thank you very much Paul Paul
  2. Hello again Thank you for your answers, all of them very interesting, and educational, before the MAK 150 I had your little brother MAK 127, for the ambition of having greater aperture, I changed it for this MAK 150, crass error, since this is heavier , more time of cooling, more expensive, and everything in exchange for little, since both gave me the same magnification, I have never been able to pass the 180X-200X without losing a lot of image quality ... now they have offered me second hand to Orion MAK 180/2700 and the seller has told me that this is great for planets and Moon, but I am a little fed up with this type of telescope ... also why I want more weight, volume and aperture but I can exceed the 200X as much ..? Paul
  3. Thank you for all your opinions and advice, I really do not have the experience to differentiate seeing or thermal problems, the Mak is always in a garage on the outside, it is not usually hot or very hot inside, sometimes I have had two hours outside before observing, and if, around me I have a lot of houses and streets without trees, a lot of concrete and cement ... I know that maybe it is not the best place to observe with high mag. I have never been able to exceed 180X or 200X, I personally with this magnification I see few planetary details ... the Moon is another story, with 150X there are nights that I see things precious, the DSO I do not even mention it ... regards Paul
  4. Hello, I currently have a Maksutov Cassegrain model SW 150/1800, I have a good chance of acquiring second hand one of these two refractors, a SW ED100 F9, and a Celestron Omni XLT 120 F8.3 acromatic and I would like to know your opinion if it really deserves the worth changing the Mak 150 for any of them, obviously the Celestron Omni is much cheaper than the SW ED100. At the lunar level-planets that would be compared with the Mak 150? In solar observation (white light)? For the deep sky I do not ask you since from my usual place of observation DSO almost impossible to realize, too much light pollution .. Mak 150 for Frac 100ED or Achro, 120 ? it really costs me a lot to reach 200X on different nights, sometimes I have even been outside the MAK for up to 2 hours, I am talking about this summer, on the other hand I am a person who does not have much time to observe, maximum, let's say one hour ... maybe the refractors are better in this sense, that is, their cooling time is less? I, by my way of observing, prefer a telescope that can sacrifice to the backyard, have dinner and start observing. I live in a place where in winter the temperature drops during the evening and the night enough degrees ... Some time ago I had an 8 "dobson and a 10" SCT and never, I could never have a sharp image, and still, she was always trembling ..., and the telescopes left enough hours outside, I think I prefer a more stable and sharp that a shaky and somewhat blurry image ..., I do not know if this would be provided by any of these refractors .. Thanks in advance Paul
  5. Hello, I have some important questions for me in relation to white light solar observing..: - Using a Hershell prism to observe the sun in white light, is it better to use it in a refractor with ED or APO lens or is it the same if an achromatic refractor is used? Better with long focal length F8 or F10 or with an F6 also worth it? For example, in visual is a 4 "F / 9 or a 5" F6 better? - From what aperture can we begin to have a detailed image with good resolution of details? - And one last question, if you allow me, for visual observation to part of the filter ND3 and Top Pol, it is necessary to use a uv / IR filter in the eyepueces? Regarding the Baader Continuum filter, does it really improve the contrast in visual, if so, from what aperture? thank you very much in advance for your advice regards Paul
  6. Hello, Anyone use the SS60-DS Daystar dedicated telescope? Thank you Paul
  7. Ted, Yesterday I tried them and they are pretty good .. thanks Paul
  8. Hello, Last night, and from a rural environment with light pollution and using Canon 12X36 IS binoculars I could not see this dark nebula, the night was calm and with good transparency, I moved about two miles away from where I observed, something far from the light pollution (although still close to it) and I could appreciate in a very subtle way the structure, image of the nebula, then I continued walking in the night, leaving me another 2 or 3 miles from the sources of light, the Milky Way began to be spectacular, I pointed to Tarazed and - OHH !! What a beautiful nebula .. moral: do not change your binoculars, change your sky (if you can ..) best regards Paul
  9. which planetary filter is best for Mars?? Thank you. Paul
  10. The north of Lanzarote, Haría or Yé for example is a good place for astronomical observations!! Good Luck! Paul
  11. Hello. I have a SkyWatcher Maksutov Pro 150/1800 telescope that have an adapter visual back to 2", a heavy 2 "diagonal, giving too much weight to the telescope when I use it with binoviewers for planetary and lunar observations, I would like to know if there is any adapter that can be attached to the exit visual of the maksutov to be able to use a diagonal 1.25 " ,or if there is one 1,25" diagonal for to put directly to visual back( I think that there is some 2" diagonal for visual back)since these are much less heavy than those of 2" .. Is there a star diagonal of 1.25 "with a SC thread? This Mak have SC thread, is the same size as the C8 models? Now I have : Large and heavy adapter that is screwed to visual back + 2" diagonal star + binoviewer + 2 eyepieces., all for planetary and lunar observation, very heavy..(for my actual mount) Which , I think added to weight of the Mak 150 is in the limit for my actual mount..I would prefer to use a lighter "train", for example: visual back 1,25"+ 1,25" star diagonal+ BV+2 EP., but I wonder if this be as robust as the "2-inch system".. There is a diagonal of 1,25" that can be put directly to visual back ? Thank you for your comment.. Paul
  12. Hello, I just acquired a SW Mak 150 and I'm looking for some finderscope that works well, is a red dot zero mag. or a 9X50 finder better? Thank you very much Paul
  13. Hello, Can you recommend me some good eyepieces for a Maksutov 150 / 1800mm focal length ? it´ve 2" focuser... Thank you very much. Paul
  14. I enjoy your fantastic images!! Paul
  15. Hello, For visual observations the best between this two telescopes? Thanks Paul
  16. Thank you very much for all opinions!! Paul
  17. Hello, Currently I have a good 5 I use it "Mak-Cass Sky Watcher model ...., I use it mostly for lunar and planetary observation, some observation of double stars, some time ago consult here, in this forum, if really it was worth changing to a 6 "Mak, there was no consensus really, it was not very clear ..., now I ask again for advice on whether it is worth changing to an 8", in this case an SCT ... I will notice difference in the images (I only observe in visual) of the planets and the moon? Currently I observe with binoviewer, it would be possible to use this accessory with model 8 "SCT as with 5" Maksutov ..? Thank you Paul
  18. I specifically asked Omegon and he confirmed it to me, the lenses have a thread for 2 "filters ...
  19. Hello, A few weeks ago I bought some very original binoculars, Omegon 2.1X42, I imagine that they will be clones to the Vixen ..., until yesterday night I could not release them, the night was quite good, although where I live in summer there is enough heat, and there is not much transparency, but I have to comment that the images were pretty good, very curious, I had to bring my eyes close enough to the eyepieces to be able to cover more visual field, and I thought maybe some nebular or UHC filters could be good to observe nebulas, my Omegon have threads for 2 "filters ..... Anyone who has these binoculars has tried a nebular filter? Thank you Paul
  20. What fascinaing Iron Man Hero!! Regards, Paul
  21. Thank you very much for your opinion and advice.. It seems a binocular to keep in mindhis observations, if they really have a good contrast in the image.. I am hesitating between these Vixen and the Vixen SG 2.1X42 model.., could someone compare them ? Regards, Paul
  22. Olly, it´s the old Trinovid model ? BN or BA ? I like one that let me observe wide angle Milky Way and bright and dark nebulae, with a good image contrasted .. Paul
  23. Hello I am lookind for a good pair of binoculars for Milky Way observations, I like bright and dark nebulae, star clusters..and I like know your experiences with some models for this ..for this purpouse which can be the best bino ? Thanks for your information.. Regards, Paul
