  1. There is a blog I write that is about using small telescopes like the one your using. I talk about what objects to look at and what you can expect to see. My last post and the next is about recording keeping and that may not interest you right now but look at the other posts. A good target for a small telescope is M81 & M82 in Ursa Major. Start with your 25mm eyepiece, you should be able to see both galaxies in the same field-of-view. Like the others said, don't expect too much. Both galaxies appear like gray smudges of light. But when you think about what you are really looking at, its quite amazing. Good luck and Clear Skies!
  2. Mid September, October and through November is an awesome time to view some some well know deep sky showpieces. Start with the double star Albireo in Cygnus. During September it is well placed overhead for mid-northern latitude observers. Very close by in the constellation Vulpecula is the planetary nebula M27, better known as the "Dumbbell Nebula", and don't forget M57, the "Ring Nebula" in Lyra. In October the constellation Andromeda is becoming well placed for viewing M31, the "Great Andromeda Nebula", the closest spiral galaxy to the Milky Way, and also the farthest object in the night sky visible to the naked eye. While your looking at M31 you may notice a couple additional objects in the field of view. Those will be two additional galaxies M32 and M110. Don't forget that the cresent and First Quarter Moon is fascinating to look at too, but use a Moon filter for better contrast. As we get into November the constellation Perseus is becoming well placed and a great target here is the Double Cluster (NGC 884 & NGC 869). A low power, wide field view is best for this object. Under a dark sky away from the light pollution of cities and towns the Double Cluster is visible to the unaided eye. Another cluster of interest here is M34. Although not as appealing as the Double Cluster it still warrants a close look. M34 is about 1,400 light-years distant and conatins about 100 stars. All of the objects I mentioned are well sutied for an eight telescope. If you don't have a sky atlas I strongly recommend getting one to help you locate these and many, many more fascinating deep sky objects. Clear Skies!
  3. I have that same book that a couple others mentioned here, great book. Someone said, ditch the finder and get a Telrad. I say use both. At some point in your quest for DSO's you're going to have to learn to star-hop to your target. Stellarium, as Ronl said is good for planning a nights observing but so is Messier45.com. Good luck and never give up!
  4. Ever need a detailed Moon atlas? Check out The Full Moon Atlas.
  5. Got a small telescope? Learn what you can see with it at 90 Millimeter Observatory.
  6. Forget the apps for now and buy a sky atlas. Take it out with you and your telescope and a red flashlight and get to know the night sky a little. Take your time and find the constellation Hercules and look for the four stars that form the "keystone". M13 is between the stars eta and zeta. You can use eta as a starting point to guide you to M13. We call this star-hopping and it's something you will need to learn to do with your telescope. Star-hopping is a little difficult at first but, the more you do it the better you will get. Remember to always use your lowert power eyepiece first. In your case it's the 32mm LX you mentioned. Also, make sure your Telrad and/or finder scope are pointing at the same thing. Such as, when you first setup for the night, point your telescope at the star Polaris and center it, next center Polaris in your Telrad and/or finder scope. That way, when you point your Telrad at the star eta Hercules, your main telescope is also pointing at eta Hercules. Here is a link to a star chart showing the constellation Hercules and the location of M13: http://www.constellation-guide.com/wp-content/uploads/2013/01/Hercules-constellation-map.gif Good luck and don't give up. Your on your way to a fascinating hobby. When you have time, check out http://90millimeter.org/ to learn more about using your telescope and what you can see with it.
  7. For me, there is nothing I enjoy more than to have someone who has never seen the Moon or Saturn or Jupiter look through my telescope and exclaim, "WOW! Look at that!" Public outreach is by far the most rewarding aspect of backyard astronomy and it's what I'm most passionate about.

  9. As far as the power pack goes you may want to look into Celestrons deep cycle power packs. Not too exspensive and 17 Ahs. As Keiran mentioned the HEQ5 should do fine but I like to have a little more mount then telescope so I use something like the HEQ6. It think it's a little steadier.
  10. Welcome to SGL. I'm new here myself and so far I meant some very nice people.
  11. Thanks everyone, it's great to be here. One of you asked if 90mm was the apeture of my telescope. Yes, one of them. I have two 60mm, one 90mm, one 120mm and one 152mm telescopes. All refractors. Way too many eyepieces, 10 x 50 and 27 x 70 binos. For photography I use a Pentax *ist DS2, a Meade #902 EEP and I just received a Celestron NexImage 5 which is the reason the clouds haven't cleared for the past month.
  12. ...you spend a few hours on fourms like this talking about astronomy.
  13. I understand how frustrating it can be. Where I live in the US we have 67% cloud cover for the year so observing time is very limited. Add the fact that I work a full time job and observing time becomes a premium. So how have I kept going for almost 40 years? I don't miss any opportunity even if its just for an hour. If the sky is clear, I get out there to observe. Even if I have to be at work the next day, I'll get out for a bit with my 10 x 50 binos or a small telescope. I save using a larger scope for weekend nights. Sometimes I go out just for a little naked eye observing. I live just a few miles from the city of Phildelphia so there's lots of light pollution to deal with but, I'm not going to let that or work or other commitments stop me from enjoying astronomy. Keep at it and look for those opportunities to gaze skyward.
  14. I am a long time 90mm refractor owner and in fact it is often my telescope of choice for moon, solar (with proper filter) double stars and brighter deep sky objects. I have observed the entire Messier catalog and many NGC and IC objects under dark skies and under light polluted skies a 90mm refractor is well suited for the brighter planets.
