  1. Time is up! I have to leave, Ill try to find some good DSO,s
  2. Hello! I would like to get a few suggestions of DSO to look at inside mainly Leo, Leo minor and Lynx, around that specific spot of the sky. I see there are many galaxies M96, M95, M65, M66 (leo) those are already on my list . But if you have a suggestion of a NCG number with a good surface brightness.. could be interesting also. If you have a nebula suggestion elsewhere too. After maybe 7 or 8 days, this is AT LAST the weather forecast for tonight, I am prying it's not a lie. (((: it looks really good for me. Thanks
  3. I am no specialist in dobsonians but what about the the Skywatcher 16 inches dob F4.4? It has Synscan and it's collapsible, takes less space, maybe easier to move around and faster to set up then other brands, good looking. I understand it may not be the highest quality of optics compare to artisanal but everything about It seems to be intelligent. Also, it's not too high, a small step could do the trick. http://ca.skywatcher.com/product/product/bk-dob-16-synscan-gps/ https://www.youtube.com/watch?v=MlR0IPSoDdE
  4. I can't help you with the telescopes but your website is really interesting!
  5. @Alan64 Okk the opening is 38mm, I did not know that. Normally to get the TFOV I do: TFOV = AFOV of eyepiece / magnification given by eyepiece Telescope C8: 200mm x 2032mm / F10.16 with for example a 50mm EP and 82d AFOV 2032/50 = 40.64x then 82d/40.64 = 2.01 TFOV but with a full 51mm view of the secondary mirror (like on a Newtonian) How can I know how much TFOV is lost because the hole in the primary of the cassegrain is only 38mm? just to get an rough idea.
  6. Is there a color filter that could help revealing the white ovals? I know neodymium helps a lot with the festoons but I never saw any ovals yet. Would be nice to catch one soon ((:
  7. When I am new at some place, I think it's better not to propose too many things (changes), unless you are a fine leader with high power of influence. Building an observatory is expensive, it's a lots of efforts to deploy for the volunteers, money and time. I would stay out of that path and look inside my own telescope (No ambition) UPDATE:
  8. @Alan64 Is it possible to use something like 50mm EP with a C8 to get low power for nebulae? a 50mm eyepiece would give 40.6x and 5mm exit pupil. I guess most of the EPs would be in 2" size.. but something tells me there is something else missing. For the first time (my first thoughts on the subject of cassegrains) I understand why some people say they are really good for planetary observation, 25mm will give 81x!!
  9. I agree totally with that!
  10. @torchlight With 130mm telescope I had many jaw dropping experiences! It's a matter of observation and taking the time to carefully look at the objects, then, you can see subtle and really interesting things! Now I use a 200mm and I don't regret the upgrade, it is worth the extra money. 8 inches is a good balance for portability (weight) and aperture to be able to see many many objects, it can last a lifetime.
  11. I would take a 6 inches reflector of good quality, they are inexpensive but effective. Collimation is not a big deal, after some practice it's easy to execute. You clean the mirror once in a few years and that also is not really hard if you follow the procedure. For me, the 6" is the best bang for the buck.
  12. Congratulation for your first nice sketch! I think the Beehive was a great choice to start with also. I recognise the cluster when I compare your sketch to my memory image, which is great.
  13. Great I am glad you like this sketch of Jupiter, it reminds me of my last trip to the field. My field spot is available now! it was my first time there in 2017. It's in the middle of a field with absolutely no lights close to me, wow I just can't believe how lucky I am to have an access there. I love that place so much it's full of memories of my first observations with my 130mm newtonian. I understand why you all have passion for astronomy, it's another calm and infinite world, a pure contact with the sky, some kind of good obligation. @Charic I like to watch Jupiter and other planets with low power sometimes, but not really to catch more details on these planets, I am thinking more of the whole picture, the planet with the stars around. It's different then a specific detail exam of the planet, to extract all the small details to sketch for instance. I am starting more and more to appreciate observation at low power, the big picture. Also, I spent maybe 35 minutes at the orthoscopic to sketch,then after, I took the 32mm with 70 degrees AFOV and it was breathtaking, WWAAAAAOOW incredible!!! Just after that, around 23:00 Montreal time, the moon came out but with a deep red color with light long dusty clouds around it, the tip of the trees plus the heat of the ground were visible. That was a heck of a moonrise! a wonder to look at and perhaps, the highest moment of my observation. You should start sketching Charic it's really rewarding to be able to save the views. It's hard to sketch a star cluster because you have to look at the EP and at the sheet maybe 100 times, that's focus / defocus many many times. The red light is not enough to draw faint stars on the paper but it's just enough to cause the loss of dark adaptation and it's messing the averted vision technique required to capture the core of the cluster or the nebula. DSOs are hard for the eyes. The use of graphite honestly is dictated by the humidity and the resistance of the paper to it. I just can't get more contrast then that with that kind of paper mixed with humidity. Pushing harder on the pencil will mark.. I wish to improve my contrast but the solution might be to change the paper. The color inversion technique is great too, for DSO drawings, thank to computers (: Gimp can do it for free Thanks @laudropb @Stu @mikeDnight@jabeoo1 for your support! you play a role in my motivation!
  14. Yet again, another sketch of Jupiter, the position of this planet is not bad these days, in maybe 4 observation in a row, a clean resolution was possible using my new OR-HD 7mm. (I am so happy with it ) This sketch was done using the 200mm reflector, 7mm HD-OR 143x and neodymium filter. The atmospheric condition were bad for the stars, a lot of scintillation but Jupiter seems to be unaffected. I would evaluate that on 60 seconds, I had around 10 seconds of crystal clear resolution, maybe more. The visual quality of Jupiter at 143x is unbeatable with anything else I’ve got in my case. And.. The GRS was visible with a striking definition and it's awesome red color. ( "roux" in french to be more precise) beautiful caramel color. The planet also looked really great at low power using my 2" providing 31x, the whole picture with the stars and the moons was beautiful and of course with razor sharp resolution. A: The GRS, B: Calisto, C: Europa, D: Ganymede, E: Io
