  1. 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.

    Windows 10...

    I agree why replace something if it's still working. I still use Windows XP for some software unrelated to astronomy.
  3. 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.
  4. 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.

    First sketch - M45

    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.
  6. ES24/68 I like that one very very much.
  7. 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.

    The chair is a wonder Sunshine, I am never going back to standing observation. it's simply too difficult for the feet...

    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.
  10. 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.

    Seeing floaters worse with higher mag.

    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.
  12. 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)
  13. 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.
  14. 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.
  15. 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.
