    Procyon region

    I have another star scene from last night, the Procyon region.. ,that is, Canis minor and about 1.55 deg of sky. (There is an error, the FOV is not 60 deg but 68 deg) Beautiful place..
  2. Thanks Ruud, my motivation is good these days, to sketch. I found another one small one to sketch tonight if I ever get the motivation to get up. My friend would be into that obviously, naming objects and releasing certificates lol, Me, I like the NGC names, absolutely no vision, no ambition.
  3. Pretty powerful sketch you have there Mariosi, it's very impressive, you caught the cloud texture very well, amazing. 24mm Explore Scientific F.O.V. 68° This is currently my favorite eyepiece too.
  4. Thanks for you comments (; yes it's a nice sector
  5. Hello! here is a small scene but of a lovely little cluster my friend found and he insisted on renaming it with his own name, hence, the Alex cluster. For me this was my first serious trip in Canis Major and we saw some very unique stuff there starting from Sirius and down. This sketch is not much but the cluster itself is a nice one with a bright white star in the middle surrounded by many faint stars. After a couple of minutes, I could count about 27 stars in my 8" Newtonian and a bit more then that with my friends 10", more then 35 stars including the averted vision ones. He was using more power then me too, so power and aperture had a notable influence on that one, especially power I think. my sketch with 8" Newtonian and 18mm eyepiece TOFV about 1 degree. and the little map Great little observation. thanks for watching.
  6. Your moon sketches are beautiful and I agree with you about the therapeutic effects of sketching and the pleasure you get when you get absorbed into it. I might do it tonight.. Inspiring Thanks for sharing the 2 great sketches
  7. Hello! this is the image I wanted to show about the various FOV of eyepieces. (Colors can't be seen at the eyepiece of course) From right to left: ES30mm 82d, ES34mm 68d, ES24mm 82d and ES24mm 68d.
  8. I agree why replace something if it's still working. I still use Windows XP for some software unrelated to astronomy. ?
  9. I did a comparative exercise between 4 different ES eyepieces (using 245mm x 1270mm telescope) on the great nebula in Orion, Stellarium can be helpful to test that. From right to left: 30mm 82d, 34mm 68d, 24mm 82d and 24mm 68d. Link deleted If this can be of any help.
  10. I think that's a wise choice for the first low power, a ES24mm 82d. I use a F5 too and a coma corrector not required for me.
  11. I like your sketch too JackCooke, very good choice of target for your first one. I can't see the nebulosity around the stars myself but I always notice a blanket of something covering the view when I look at M45, the background is foggy. It's a misery. It's a great target.. thanks for sharing your sketch and motivation here.
  12. ES24/68 I like that one very very much.
  13. I think a 10" is big and cumbersome, the 8" is big too but not has annoying has the 10" (Especially my 8" which is only 1000mm long against a thick and long 10" dobson based). I tried the 10" against my 8" and the 10" is beating it on nebulae and other DSOs. But, because of the weight and size, the 8" still wins for me. So, between a 6" or a 8" for me the choice is purely a matter of size and weight, comfort. If this can help.
  14. The chair is a wonder Sunshine, I am never going back to standing observation. ? it's simply too difficult for the feet...
  15. Hello SGL, I am very happy with my latest observation, which I am just back from. I now have a lovely adjustable chair to do my observations and this was my second time with it. I can't explain how better it is to sit while observing.. it's truly the paradise now (; So I started my observation with Mars, spent perhaps 30 minutes on the planet trying to capture some nice features. Transparency was not very good, 2 out of 5 but I had some good views of the planet anyway. I used 3 eyepieces on it 9mm, 111x, 7mm 143x and 6mm 167x. The best deal tonight was the 7mm with the Celestron Mars filter which if find absolutly excellent to reveal the darker features, it has a magenta color. Bellow, my sketch done with my 200mm Newt, the 7mm and the Mars filter. Frankly this was an interesting planetary observation. I am trying to figure out now what these Albedos could be exactly, this bellow is the Nasa simulator, probably a correct side view. Similar to my observation. https://space.jpl.nasa.gov/cgi-bin/wspace?tbody=499&vbody=399&month=11&day=4&year=2018&hour=11&minute=30&fovmul=1&rfov=0.05&bfov=100&showac=1https://www.startpage.com Thanks for watching.?
  16. I try to be reasonable with the apparent field of view of my eyepieces, remaining in the 60 to 68 degrees range, decent quality. Just by doing that, I saved serious money. I have my explore scientifics for low power with the F5 newt. well corrected, they do a fine job while being less then half the price of Televue. For medium power, the Xcel LXs and Starguiders are also doing a fine job side by side with the ES. Finally, a couple of orthoscopics for high power planetary viewing. Nothing too expensive in my case, only thing missing is good weather.
  17. Same thing here, I think it's normal for everyone at some level. 4mm with a Barlow I am not surprised the views were terrible. I start seeing small floaters on the moon with an exit pupil smaller them 1mm, at 0.94mm precisely but it's not that bad.
  18. It's a matter of spending top dollars to reach the last % of performance. I can spend a couple more years with the Xcel LX 18 and 9 has well has the Starguider 12mm for sure. (Delites and Panoptic will wait until there is a golden opportunity only) ?
  19. Forget Televue, hehehe no problems I had in mind the Panoptic line or the Delites, these are the only lines I would be interested to own eventually honestly. Probably both would beat the Xcel LX.
  20. When looking through the finder keep both eyes open and use the eye not looking through the finder to look at the star you are lining up on. It seems a bit strange doing this at first but makes alignment much easier once you get used to it. Good luck =========== This is it, efficient technique.
  21. My Xcel LX 18mm resists the test of time so far, I think it's a keeper. Probably until I try a Televue someday, against Explore Scientific the 18mm is still standing.
  22. @stokeben You can check out this very good collimation guide bellow. It will focus more on using a collimation cap or cheshire sight tube, both tools are effective tools. With absolutely no money, a simple 1$ cap could save the day to collimate a Newtonian. ? You can build one yourself too. http://www.astro-baby.com/astrobaby/help/collimation-guide-newtonian-reflector/ Here is a cap from the land of the free. https://agenaastro.com/rigel-systems-aline-telescope-alignment-eyepiece.html

    Mars 31/8/18

    These sketches are very close to what I have in my memory from my latest observations. very nice. Good idea to write the diameter of the disc has well has the phase.. I will do that too.
  24. This is my DIY filter, I took the instructions from Baader to build my own version, they tell you how to build the filter support inside the papers. My filter is close to 200mm aperture and I can put some interesting powers on the sun, I used 212x in the past to look at the dark spot and it was super interesting but also very hazardous. The filter is quite effective but I stopped using it a while ago after a discussion we had here about the pinholes in the Astrosolar sheets. For me, It's not really possible to know if these sheets are safe or not for prolonged use. And a real solar telescope is expensive.. so. I am scared.
  25. It has a 9x50 finder scope, I would try it at least before replacing it, unless you have some neck and/or back problems. For star hopping I find it a good tool, straight-fhrough finder scope nice quality too. Many people don't like them but it has some power in it, you can see some faint stars with it while star hopping. You can use both eye to star hop, one looking through the finder and the other eye looking at the sky. That's very effective finder in fact but not always comfortable. I like mine very much.
