  1. This refractor in the 80-100X territory for visual daytime , how is? Thanks Tico.
  2. I have used with good tracking results some spotting scopoes (some with ED lens) and I have been able to see good details and liveries with 60X and a good manfrotto tripod with a 501 head, the maximum in these spotting scopes, all with zoom eyepieces, but I lack some magnification, I do not speak 125 or 150X, it would be a lot of power and it would be difficult to follow, but the 80 0 90X would be very good, it would be the mag. almost "perfect", a good balance between presentation of details, good tracking ...
  3. Thanks all comments!! Two questions: - Can all three filters be used together on the wedge? I mean, ND3-Conntinum-Polarizer? the three at the same time will not subtract too much light from the image? - Is a solar wedge good for visualizing solar granulation? And one last, do you know any web address where you can see images in white light through a solar wedge? Thank you very much. Tico.
  4. Hello, I am looking for information on some telescope that I can use to observe airplanes when they fly at high altitude ... Well, I will tell you my little story, I will try to be brief, it is essential to be able to use a zoom eyepiece because first you have to locate the plane with low magnification, then go up little by little without losing the visual field, if it gets lost it goes down to lower magnification and start again, I have done it with a short refractor telescope, (with a long refractor it is impossible, it is very low, close to the ground) and an image erector, but these refractors usually have a low focal length and then with the typical zoom From 8-24mm it reaches a maximum of 50 or 60X, clearly insufficient to see it close, its characteristics and livery ..., I have not tried the image erector + barlow, so I do not know what such a result this setup would give. . On the other hand, I have used the odd spotting scope, very good in the sense that they are very manageable and fast in search and monitoring (they are short in size) but they only reach 60X, which is little to observe them at altitude. On the other hand, I have thought that perhaps a small 90 or 100mm Maksutov, having larger focal lengths, 1250 or 1300mm, could achieve higher magnifications, but the problem may be that the smallest magnification is a bit high, around 50X, ummm , and I don't know if the visual field would be too narrow ... I understand that AC would be zero .. I would be delighted to hear your opinions about it or if you have used a good telescope in this regard. Best regards Tico.
  5. I´ve two possible refractors one ED80 and the other is one 127mm.. Thanks. Tico.
  6. Hello, Currently I am looking for some information on solar wedges, I have heard that they are quite safe and that they are very similar to each other, I have seen that there are Lunt, Baader and Lacerta, Altair ... as main brands, maybe there are others. I have read that Lacerta has a special characteristic, the angle in 56.6 degrees that the prism presents, will you notice a difference in the solar image in relation to those that present the prism at 90º? I would also like to ask you, apart from the ND3 filter, which filters are worth putting in the sun wedge? I have read that if a polarizer, that if a solar continuum, that if another of lower density neutral density ... in short, a whole mess for me that I have never had a solar wedge ..., I want it for visual observation! Ah ... I forgot, is it true that 1.25 "wedges are only valid for refractor telescopes up to 4"? and the 2 "ones for refractors up to 175mm? Thanks in advance for your valuable advice. Cheers, Tico.
  7. Hello Currently I have a C8 with which I observe the Moon, the planets and some very bright Messier, this is what I can observe from my little corner of observation, which is from where I usually observe, the planets and the Moon are the most apparent objects, Lately I am thinking if it is worth changing the C8 for some refractor that would give me better lunar and planetary images, the truth is that with the Moon I have no complaints, the image is very good, I observe with binoviewers, but with the planets I do not have So lucky, I have a hard time getting an enlarged and stable image..that is why I would like to ask you if it is really worth changing the C8 for an 80ED or an ED100 refractor..for visual planetary and Moon. Very kind for your comments. Tico.
  8. Hello I would like to know what diameter a refractor must have to be able to observe the solar granulation well, with a solar wedge? I have observed with a 3 "and 4" refractor and full aperture filter, and an 8 "SCT and I have never never been able to observe this granulation ... Thanks.Tico.
  9. Thanks for your reply. And what such result has it given compared to the previous refractor? better resolution and images of solar granulation? Best regards.
  10. johninderby, How well has the Hershel prism given you? Have you been able to get a sharp image with medium magnification? Can you observe solar granulation? I ask it because I have a refractor like this and I am thinking of doing solar observation with it. Thanks and best regards, Tico.
  11. Hello, I´m looking for a barlow lens or a Powermate for high magnification with my ED80 F/7.5, which is best for this purpose? Or maybe one short focal eyepiece of 3-4mm best? Thank you. Tico.
  12. Hello, I'm looking for advice on which refractor model can give better results in planetary observation, I'm looking for one between 3 "and 4" in diameter ... I don't know if an achromatic with a long focal length is better or if one with ED or APO lenses. .. I would be delighted to hear your opinions and advice. PS: I have ever observed by some Newton or SC and the images are very unstable, very shaky, they lack as contrast ... Thank you very much. Tico.
  13. Yes, is the Bresser 102/460 with ¿ED? lens ? Is one fantaastic wide field for low magnifications, 4.7º in the field can be great ... Thanks for all comments!! Tico
  14. Hello, I was looking for some advice on a good wide angle eyepiece, about 30mm, although I am not very clear if it is better to 82º or 72º ... I would like it to give about 5º of field .., one day I looked at a 31mm Nagler and I did not like it very much. feeling of having to move my head to see the end of the field, that is, at a glance I could not see the entire field ... My telescope is a 4 "/ 460 FL refractor. Thanks. Tico.
