  1. I finally got around to reading the August issue of Sky and Telescope magazine. Just happens to be an article on our topic, spectroscopy. If you can get a copy of this article, it will be another resource to learn and get in to it.
  2. A short while ago I was interested in spectroscopy. I read a couple of books but never went any further. I did come across a book by Ken M. Harrison called "Astronomical Spectroscopy for Amateurs". Bought it from Amazon.com. I thought it was a very good read. He has a other books on the subject as well. Ken Harrison also has Yahoo user group on spectroscopy that seems to be very active. Perhaps a good resource if you join the group.

  3. The central star in the "The Blinking Nebula", NGC 6826 in Cygnus is easy to see. Very easy when you alternate looking directly at it and using averted vision.
  4. If you are using the ring technique, you need to know the FOV of your finder scope. Then with what ever atlas you are using, make the ring the diameter that will match the FOV of the finder scope. The ring will now only be unique to that particular atlas. I made my ring with my atlas, "Pocket Sky Atlas". I cannot use this ring with "Cambridge" or any other atlas.
  5. For folks that are trying to learn how to star hop, I am that glad you brought this topic up about making rings to match the FOV of the finders scope. For me, star hopping did not click in my head until I made such a ring. During the day I can practice the star hops with my star chart of the objects I plan to see that night. Sure enough the star field inside the ring on my star chart is pretty close to the star field at the finders scope. Just keep in mind the type of finder that you have, a straight through finder or a right angle, correct image (RACI) finder. If you have a straight thro
  6. The washers is a great idea for my Orion Astroview mount. I see myself doing this particularly for solar viewing in the daytime. At night I can set the tripod in my spot and then get a good polar alignment. Then set the washers under the feet.
  7. As far as polar alignment, if I'm in a hurry I just set my mount to north using the compass on my phone. You have to ensure that the compass is set for TRUE north. That is also what I do when I'm setting up to look at the sun because obviously you cannot see Polaris in the daytime.
  8. My Orion Astroview 6 EQ is an EQ-3 mount and it shakes a bit while focusing. I solve the shakes by installing a motorized focuser. Contact Celestron and see if they have one compatible to your focuser.
  9. My Orion Astroview 6 is a similar scope to your Skywatcher. I bought a case from amazon.com that is awesome for it. It is the Plano Model 1819 case and it even has wheels. It is no Pelican but it gets the job done. I can get the OTA, tripod, mount, counterweights and more all inside. https://www.amazon.com/Plano-Molding-1819-XXL-Storage/dp/B000UPGMXY/ref=sr_1_4?ie=UTF8&qid=1490239661&sr=8-4&keywords=plano+1819 Here is a picture of it with my gear inside. Keep the original packaging for protection.
  10. That mount looks familiar. Anyhow just one correction, the knob you circled is actually called the "Latitude adjustment knob". There one in the back, like the one you circled and one in the front. In addition, in the front of the mount under the front "Latitude adjustment knob", there are 2 round knobs called the "Azimuth Adjustment Knobs". After I set the scope on the ground I point the leg with the label "N" towards the star Polaris, eyeballed the best I can. Then I adjust these knobs until Polaris is centered in the eyepiece. To adjust the knobs you loosen one and the tighten the othe
  11. There is nothing like an EQ mount that tracks. Here is an article on using the setting circles. I've had some success using the setting circles and some failures. More success however. Here is a link to the article on how to use the setting circles. It sure helped me. You really need to get a very good polar alignment in order to have a chance for the setting circles to work. To improve accuracy of the setting circles go to and use the coordinates of a bright star near the object you are trying to find. For example, due to my light pollution I had trouble star hopping to M11. Therefor
  12. The 150p might similar to my Astroview 6 from Orion. I'm able to get prime focus two ways. One way is with my DSLR with t-ring and t-adapter placed into my Barlow. Second, my eyepiece holder on my focused can unscrewed and removed. Threads are exposed where a camera with only the t-ring can be attached to the focused. Your focuser may be the same as these scopes may be made by the same folks, Synta.
  13. I can get prime focus with my DSLR with my Orion Astroview 6, a 6 inch f/5 two ways. One, with my 2x Barlow. I attach a t-ring with t-adapter to the camera and place then put it into the Barlow. The second way is that I found out, the instructions didn't say, that my eyepiece holder can be removed exposing threads. Now my camera with the t-ring, no t-adapter, can be attached to the focuser for prime focus. Perhaps your focuser is similar where you can remove the eyepiece holder if it has one. If not you may have to replace your focuser with a low profile one. There are several vendors l
  14. First of all, what mount do you have? I polar align my mount in the following steps. 1) Set tripod/mount on the ground with the label on the the leg labeled with an "N" facing true north or Polaris if you can see it from your observation site. 2) Level the mount. Use the bubble level on the tripod if you have one or use a regular level. 3) Set the latitude scale to the latitude of your location of your observing site. On the side of the mount there is a scale that can be adjusted with loosening and tightening the latitude adjustment knob until the marker points to your latitud
  15. I got into this hobby about 6 years ago and bought my first scope, 6 inch reflector on an EQ mount. I learn how to use an EQ mount and got good at star hopping. However, I live just outside of Chicago and the light pollution is bad. Some nights I can barely make out the keystone in Hercules. I could star hop to the easy stuff like the Messier globs,open clusters and bright nebulae. It came to a point where I could not star hop to some of harder stuff because there no stars to star hop to. Then I started to learn and use the setting circles with mixed results. I did find some stuff with the
