  1. Hey. I just got a bargain on the 12" dob goto since the previous owner was open about the scope having some tracking and goto or electronics issue Now I figured out what's wrong. The alt axis works fine, and as expected, but the azimuth motors axis over react to every impulse So regardless of what slew speed I set, it will always move the scope the same about in the az direction when I press a button This is, if course, full crisis for tracking. The scope just does fast 360s Anyhow. This miust be on the motor controller side right.? I can't see that this is a sy
  2. Hey. I just got a bargain on the older skywatcher 12 flextube dobsonian. The main reason for the price, was that the electronics are faulty. According to the previous owner, the scope acted erratic on tracking. Ha also misplaced the cable between hand controller and az motors. I have a few ways forward. Can I disengage the motors and use it in manual mode, ie. Get more fluid motion than now then the motors act on the movement? What cable would I need between az motors and hand i controller. Can I upgrade to the latest WiFi system? Can I hack or make somethi
  3. Now that I only do visual astronomy, I tend to get a lot more astronomy done. Before, I would not bother to set up the imaging gear if the sky was not clear for the night. Now I get a lot of "opportunistic" and very efficient "hole in the clouds" sessions. That is fantastic! Last Tuesday was such a day, and I had a clear view of the moon for a couple of hours before the clouds rolled in. The air was very calm and the view through the ES 82 degree 4,7 was breathtaking. The eyepiece and the Megrez 90 team up display the entire moon at 132x magnification. That view will, 100% - mone
  4. The sky would be clear and all stars showing if this was the Northern lights. It was very strong this night, I see it from time to time but not that clearly.
  5. You might have spotted the northern lights. I see it from Oslo/Norway tonight. Sometimes it is visible this far south, it was pretty strong an hour ago or so.
  6. This was totally new to me and very useful information! Thanks for taking the time to write it up. Terms floating around like "light bucket", can easily produce a mental model of aperture as an "opening" for light to "pour into". Larger aperture, more light. I have read up a bit on exit pupil. If I understand this correctly, the purpose of a larger scope is to get to higher magnification and at the same time produce an image the size of our average pupils, when the light hits the eye. Exit pupil size is determined by how fast the scope is, not the size, but larger telescopes can ha
  7. It's very interesting that you said that about M92. I double checked the location. I thought I might a have come across a bright compact galaxy. I can imagine that is how they look in a larger telesopes
  8. I sometimes set my telemator up on the front side of the house , facing south, to observe the moon and Jupiter. My megrez 90 is then at the balcony opposite side. After that I bother my family, turning out lights and running through the house, back and forth Dark adaption is impossible anyway. We oversee a small town from our house and the lights from it constantly disturbs my night vision.
  9. From my balcony, I only have good visibility North and East. That limits what I can see form home, but the seasons bring enough diversity to keep my interest. I can get a peek through my roof and the house next door and I found Cheretan in Leo with my 33mm. I tried to spot the Leo triplet to get an idea of how good the skies where. I could see absolutely nothing, and knew that Mag 9+ objects were out of reach. Hercules is in a good spot nowadays, So I decided to check off a few brighter messier objects of my 2016 list. I have spotted M13 earlier this year in my 60mm 1960's refractor, bu
  10. I am refurbishing a Weltblick 60/910mm Circle K (Kenko) refractor from the mid-late 60's. These were produced in Japan and sold by department stores under a wide range of local brand names at the time. The only way to identify the maker and time of production is to look for identification symbols and "passed" stickers. The kit was dirty but very complete, dust caps on finder, scope, eyepieces. I have fixed a slack problem on the RA Axis, and taken the EQ mount apart to its last part, polished, cleaned and re-greased. The mount is now butter smooth to operate. In the picture, you see
  11. Yes, I think it's worth it. The telescope and mount are in very good overall shape for its age, and the kit is nearly complete. It feels good to restore, and improve its function to something useable that fills a hole in my current setup (slow refractor). I have the Zeiss, but the wooden tripod and cast and solid EQ mount has it's charm. I can also very easily set it up as a solar scope, with a new filter, if I want. The gear is included in the kit. The Jason is in transit
  12. I and my Weltblick have had quite a journey since I got it. After first light I noticed a couple of problems with the optics. Star images were okay, and the moon looked good with little or no CA. The view of Jupiter brought out the problem. The planet showed a couple of yellow halos, the size of the planet . It was also difficult to get a good clear image because of glare and internal reflections. Looking more closely at the lens it had traces of vaporized fluids and dust between the air spaced elements. I got some help over "at another forum, with a lot of classic telescope
  13. Beware that this is a bit like upgrading your TV to a 50" from a 24" without switching from the antenna on the roof to HD cable. You will get a 50" image on your TV, but it will be magnified noise. If I am going to throw a lot of money at Eyepieces, it will be large FOV ones. I have a "cost efficient" William Optics SWAN 33mm / 70 degrees FOV. I thought It were pretty good until my first night at a decent sky. Looking at the double cluster only half of the FOV were pinpoint stars, the rest of the large FOV looked like c*p. I wanted to cry and bury the EP in the snow then and there. I use
  14. Also... After viewing Jupiter almost every session for the last two months; as a novice, the eyepiece doesn't make a difference. The seeing will always be the limiting factor. I doubt that the the views will be dramatically better in super expensive EPS, even on the rare, very good slseeing nights. At least compared to 'okey' EPS. My limited experience so far is that is impossible to throw money at Jupiter. Patience works my best views so far of the red planet is with a Polarex 60mm vintage refractor and the stock (Polarex 7mm) EP.
  15. Just want to chime in on the praise for the Vixen SLV series. I only have the 20mm, but the eyepiece is very well built and a pleasure to use with the good eye relief and the rotate-to-extends eye cups. They are made with a high friction, rubber-like material, so you won't drop them by accident. I also have NLVs for higher magnifications. Good performers, but no the same "feel good" build quality about them.
