  1. I owned the Powerseeker 127EQ and your image is the reason (one of many reasons actually?) that I upgraded. After the upgrade and with better eyepieces, the 127 still gave no better result! Your seeing conditions may not be the best, we have to wait long and often for fleeting moments of crystal clear steady images, but I'm more than happy with my present setup due to the larger aperture.
  2. I would have thought that any thermal disturbance above will affect every telescope! The important thing to remember ( here goes!) the primary task of the astronomical telescope is to gather and focus light, therefore the bigger the objective/mirror/aperture the more light you can gather, therefore it stands to reason that the bigger it is, the better it is, but no, there are limits, caused by the scope itself and the atmosphere your looking through, and if those atmospheric limits were removed, then the design of the scope itself would still have a limit as to what it can achieve. The telescopes ability to gather and resolve is all about aperture, and having more light to play with, you can/should be able to observe finer details when using an eyepiece, again one suitable to/for the task. Next, the focal length of the telescope is important, as it controls the power of the telescope, How! The focal length of the telescope divided by the eyepiece focal length determines the power of the scope. You could have say 5 telescopes with different focal lengths and apertures, but with careful consideration to the eyepiece in use, they could all produce the same power, but invariably, the views may look different in contrast and field of view, dependent of the design of the eyepiece, but all producing say 100x power. As to when to step down in aperture, thats a personal choice only you can observe. I use an 8" aperture (200mm) yet I can downsize the same scope to a 2" (50mm) aperture, and all I can detect is a slight dimming of the target, which in this case is when I observe the Moon due to its brightness. I have never tried to lower the aperture for/on any other target, as I want the most my scope can capture.
  3. Ive used an alternative to the ever-so sticky 3M pads when I mounted my Telrads! but belt and braces security, they were also tie wrapped, but tie-wrapping allows you to find a suitable position before sticky or bolt mounting. Don't forget try all the angles once temporary mounted. Its ok setting up your finder when the scope is at say 45° but will it be comfortable for you anywhere between horizon to zenith? I have an idea for a ring of holes 12.5 to 25mm diameter with the lower edge of each hole in a position that aligns with the surface of the mirror? as viewed with the scope upright? but if I actually go ahead with this idea, both end cheeks of my Sky-watcher can be removed, and if carefully marked and handled, I'm certain for one that no swarf or tool damage will occur inside the scope, and with careful re-application of the cheeks, the scope will, in all probability, still be collimated! if not, thats not an issue for me to correct. Like I said its just an idea for now. Do what you feel is best. but once cut or drilled, there's really no going back, although drill holes can be plugged with rubber grommets. Also consider the re-sale value after any modification?
  4. I've found no matter what the base level, there is an improvement in either direction but with conflictions? Go lower and the image can be sharper but smaller, yet go higher and the image does get larger but less detail.
  5. Just caught your email prior to going to work! I bought the EP second hand to trial against my other 6mm EPs As for condition, apart from the little mark visual above the green bi-directional arrow in the image, you might not find better unless brand new. There are less visual marks on the barrel where the barrel fits into the focuser, this should show more signs of wear! I think the build quality helps to protect the barrel. Part of my feedback for the 8mm recently sold (for more money) but of the same high quality " ......goods in excellent condition....." Age wise! I bought it from a member here at SGL September 2015. HTH. As t shipping, good communication. Goods in excellent conditionrGreat ebayer, fast shipping, good communication. Goods in excellent conditioneat ebayer, fast shipping, good communication.

  6. After quite a difficult day, nice to have a laugh with/at someone else? The closest I can get to Ca2SbMg4FeBe2Si4O20 is Horse manure! I'm sure its worse than that though
  7. I would imagine that unless one lives under pristine dark skies, then most folk will not truly appreciate the performance of their telescope, at their given site. For me the difference between my observatory and a dark site was absolutely stunning, as if I had somehow ended up with another, larger scope, bettering the performance of what I know is good already! and all this magic makes place with just a short drive ( when I have the time and make the effort) .
  8. I went from the Celestron 127EQ and the difference for me was big, both with the visual result and the ease of use and setup. I have also considered a larger scope, but looks like I'm staying with the 8" Skyliner. There are several reasons against me owning the larger scope (size, weight, expense, focal ratio, storage and transportation) but reason for was for the larger image provided, and if luck strikes, I still may upgrade, but for now, the 8" remains.
  9. ....and why choose a scope like the 8" ? The results speak for themselves when conditions allow, good choice of scope. I have also considered an upgrade, but I think I'm going to keep this one as long as it lasts, its that good! Get the 8" to a proper dark site, no man-made light pollution and be even more inspired, although with regards to the OP their not much good for astrophotography, unless the Dob has tracking.

  12. Looks like a tidy setup, and with adjusters too, Can you still move your scope manually or do you have to use the controls? I only get a twisted neck when looking straight up through the basic 9x50 finder, otherwise its comfortable for me as I only observe from a seated position. Not sure I could stand next to my scope, would be just too uncomfortable / un-steady!
  13. C L O U D S ! Aaaaaaaaaggggggggggggghhhhhhhhhhhhhh!
  14. I'm trying, 8x40, 10x50, 15x70 still no joy, probably not looking in the right area, and my sky is dark enough with my temporary street light shielding. Even the skyline is out but looking straight up, Im having to use the 32mm as a finder? Jupiter has just risen (for me ) above the roof line, so a few hours time it might be in just the right position! .......Just checked the web and I am looking in the right area for 41P, so back to check again!
  15. Welome to the SGL. I only observe visually (for now) but there are many folk here well into the astro-photographic side of the hobby. You'll be in good hands here, its just up to you how often and when you ask the question?
