I took off from work at about 2 pm to give me enough time to reach Hassaan's place. It was my first trip there so I didnt want to be late. Going from...
If I am not mistaken, Holland is where telescope was born. ... From: Johan To: Discovery-Dob-Users@yahoogroups.com Sent: Sunday, March 01, 2009 2:50 AM ...
On Friday afternoon Mr. Umair Asim sent me an sms saying that there would be an observation session at his home that evening and if I would like, I could come...
Hello Bruce, I have used the Discovery DSC package on both my 15" and 20" PDHQ's and have never had an issue on either scope. Are they among the best...
Hello Johan, Thanks for the information, I will be picking up my scope today (Sunday) Got a great deal on a Discovery 15" f/4.2 PDHQ split tube on Cloudynights...
New member intro, longish… My 10yr old daughter pulled me back to the stars. History: Growing up I wanted a telescope. Large family, tight budget, and no one...
Forgot to mention, I was putting off buying a scope because I wanted to get a 17.5 truss from discovery. So I guess this 10" will be our "trainer" before we...
You might find the short 5-8mm eyepieces won't be as useful as something a bit longer (9 to 12mm) because of seeing conditions found on most nights. On my 8"...
Welcome back to the fold, Richard. Nice find on that 10-inch; always good to hear a neglected instrument has fallen into caring hands. This is actually a...
I'll head over to talking telescopes, but first... why was it said that Discovery Telescopes are not what they used to be? I had always heard good things and...

We enjoy observing in cold weather here. You just have to dress for it. I know in some places it is just too cold. We observe all winter long. Soon the spring...
... You are right. The cold can be dealt with. To be truthful, the last two winters I have not been as focused on astronomy and haven't been as motivated. The...
Chris - Thanks for the input - I'm trying the Astro Systems holder. Another question for the group: What do I need to adjust when my collimation under star...
... Ari, I have often noticed this myself. The off center secondary shadow in the unfocused star is more evident in one direction than the other. Focus either...
Hello, I picked up a used 15" Discovery truss dob a few years back, used it a few times a year and never like the collimation screws for the secondary. I...
