  1. 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)
  2. 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.
  3. 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.
  4. 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.
  5. @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

    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.

    Solar Viewing

    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.
  8. 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.

    Some advice on Zoom Eyepiece

    I had a Celestron zoom previously and it used to be great learning tool for me, with the zoom I learned about the apparent field of view of eyepieces especially. The zoom was +-24mm 40 degrees AFOV to 8mm to 60 degrees AFOV. IMHO I think it's essential to have at least 60 degrees of apparent field of view at 24mm. I would prefer a combo, a zoom but with a good low power eyepiece.

    So Much Easier.....

    I have a box with 12 separations to store filters, I like to have access to all my filters at the same time, just like your eyepieces setup there. I was almost told it's an idiot plan to drop them all at once.. but I still prefer the convenience of opening only one box instead of many individual ones. I think your system with the eyepieces on a shelve will be fast and effective. But personally, I would add a +-70mm border around the shelve to prevent an unfortunate accident, all the eyepieces on the floor. I admit I would be tempted to install a retractable awning on the window too, just to hide the 30mm ES at least, what a beauty. You observatory looks very nice @cloudsweeper

    Anybody Use This For Dew?

    The 12v seems like a bad idea to me for various reasons: - Is the wire long enough to reach the telescope? I know I would need a couple of meters to do that but I doubt the wire of the 12v dryer is a couple meters long. This one bellow draws 13 amps @ 12 volts.. so the wire must be quite short. https://www.amazon.com/Compact-Portable-Car-Hair-Dryer/dp/B004H30IZS I would get the gear in the car and start the car instead. - 13 amps at 12v It's not good for the car battery. - My 12v outlet is 120w max.. and using a cheap chinese heating device very close to the limit of the circuit is a risk by itself, especially at a remote spot. I vote for a refund from Amazon and using heating straps instead. ========================== I built my own dew heater from the instructions bellow total cost was about 85CAD without a 7Ah 12v Lead battery (which is about 25CAD:) I have 1 strap for eyepiece, 1 for secondary mirror, 1 for primary and 1 for the finder. With imagination you can build any kinds of custom heating straps, it was a fun project perhaps not easy, but fun. http://www.deepskywatch.com/Articles/newtonian-dew-heater.html

    2018-08-22 - Moon: Mt-Harbinger, Krieger and Prinz

    Thanks Bradley, I find the moon to be a good place to practice. Next time, I want to try to put more contrast, more strength on the pencils to get darker shades.
  13. Hi! I am just back from a nice observation mainly of the moon but with a few other objects too. My observations led me to a collection of mountains and 2 craters, Mt-Harbinger, Krieger crater and Prinz crater, it's very close to the Schroter's valley. It took 30 seconds to select the sketching target, I liked these mountains and crater instantly. My sketch was done with my 200mm Newtonian, inverted image, and the eyepiece was a HD-OR 6mm 167x, the most I could get. I also used my new #15 Yellow-Amber filter which was of good help to dim down the light and well, helped my eye a lot with the task. Thanks for looking!

    Telescope for sketching

    If you like sketching, I don't think it's a good move to skip the tracking.. even if it's not required. 2 weeks of every month you have full high illuminated moon and it's not good for sketching DSOs, but you might have the planet and moon available which are very nice to sketch too. Usually I like to put the maximum power available on my telescope for these objects, between 111x and 212x. Trying to sketch at these powers is not very convenient, it's possible.. but not optimal. One instrument I find really attractive is the Skywatcher 8" Synscan Dob. It's à F5.9 so you should be able to use mid range quality eyepiece without too much aberration problems, it's not too big and it has good 8" aperture for DSOs, you can sit while sketching, you have tracking and it Goto has a bonus... http://ca.skywatcher.com/product/product/bk-dob-8-synscan-gps/ There is a 10" (F4.7) and a 12" (F4.9) version too but you should see them first, they are big, higher and heavy, much more expensive too. Just a suggestion.

    I'm in a difficult position!

    These 3 are toy telescopes! unless it's for a 6 years old (first scope), I would also save some money to get something better...
