  1. I have recently received an online purchase of Canon 12x36 IS iii binocular. Being my first IS bino, this is indeed a very useful feature. However I wasn't lucky enough to receive a copy without collimation problems, that some older posts on here seems to have mentioned. It is not an absolute disaster, to have completely two images formed, but it is enough misaligned to cause that unpleasant feeling that makes you not want to look too much time through them and feeling eye strain and discomfort after a while. Is there a way to try to fix the problem for this model (other than returning)? I wonder if other users had this issue recently. Thanks
  2. I own a pair of these; I also own a pair of Nikon Aculon 7x50s. I picked up the Celestrons after owning the Nikons because I host community events and wanted an extra pair to hand to other people's kids. I also wanted to know what to recommend for beginners. The build quality is good (nothing rattles, and collimation is tight across the range), and the image sharpness is fairly crisp at the center of the FOV. However, they suffer from significant vignetting, and the image quality suffers considerably along the edges (with only the center 1/3 circle being crispy, and the outer edge being downright blurry). In comparison, the Aculons are slightly brighter (if at all), but the image is sharp and consistent across the entire field. (Nikon claims they use aspherical lenses to achieve edge sharpness, so that's what the extra $70 buys you vice the BaK4 prisms IMO.) The Aculons are more forgiving on where I place my eyeballs (whereas I have to fiddle with the Celestrons to optimize the placement of the exit pupils). The Aculons are longer and a bit heavier (900g vice 765g for the Celestrons). The Nikon case is padded. And the Aculons come with dust plugs (vice caps) that don't fall off the objectives. I spend most of my time using my Nikon Action Lookout II 10x50s, so I'm not all that vested in which of the 7x50s is better. If I only had $30 to spend, the Celestrons are the only choice. But if I only had $100 to spend, what I bought would depend on how I planned to use them. If I were buying for a Cub Scout troop, I'd buy 3 pairs of Celestrons. If I were buying for myself, I'd get the Aculons.
  3. Reading this article, I realized he is such a great man. May he find rest in the blossom of our Lord Jesus Christ
  4. Beautiful susnset.. If you had waited couple more minute you would have get a beautiful Golden Hour....
  5. Bosun could be right Afterall. I'd advise you do a factory reset also..
  6. Sorry I did not specify the equipment that i am using. I have a Celestron AVX mount and an 8”SCT with wifi module and the StarSense camera. I am trying to perform this alignment because when I GoTo an xxx star it is not centered on the eyepiece. For visual observation I have no problems but I am preparing for short exposure Astro photography with a Nikon D5300. But I am not there yet.
  7. Polar alignment: to Polar align my telescope mount I had to raise the mount around two feet to surpass an inevitable obstruction in order to see Polaris, but then to be able to do visual observations I have to, on occasions, use an small steps ladder. I was wondering if after Polar Alignment I could lower the mount (maintaining equitative distance between the triangle touching the ground) without losing polar alignment. I am not a trigonometric expert so I was planing on using a yard stick to do the measurements. I have used PS Align Pro app and it is good but not perfectly good when compared to visual alignment using the polar alignment scope. Thank you in advance for your advice.
