First Light - 10" Zhumell Dob new
      #2401467 - 05/17/08 08:24 AM

After 23 days of waiting my telescope finally arrived this past Thursday. Of course the weather forecast said clouds and rain until early Saturday morning.

After much debate and checking Clear Sky Chart, actually it was a 2 second decision, I set the alarm clock for 3:30am before going to bed Friday night. I figured if I was too tired I would kill the clock and roll over. But I felt more like a kid on Christmas morning than I tired man. Which is odd because I'm not a morning person and waking up 3 hours earlier than normal is not for me.

I walked downstairs and took a quick peek skyward. The view was breath-taking. It was dark. The stars were everywhere. I could even see the Milky Way going across the sky.

So grabbed my scope and out the door I went.

Since I'm normally not up at this time in the morning I was totally unfamiliar with the sky. My normal viewing is 9-11pm and I just started observing in early April with my binoculars. Anyway, after a quick collimation check I looked for the brightest object to align my finder and Telrad. There was Jupiter sitting in the south. I grabbed my 32mm EP, focused her in and WOW!! The view!! I didn't see Jupiter yet but still. The stars. They were everywhere. Sure, I have been observing with my binoculars but it just isn't the same.

After I picked up my jaw I got back to the task of alignment. It should be simple enough. You would think finding something 318 times larger than the Earth would be easy. I figured I could just point the scope in the general direction and search around a little with the eyepiece. NOT! After about 5 minutes futile searching for Jupiter it finally hit me. Aim the scope at the tip of the tree line stupid. You know what, it worked. I finally aligned up the finder and Telrad.

I slewed back to Jupiter using the Telrad and there she was with 4 moons in view, 3 to the right and 1 to the far left. I really like the Telrad. I must have sat there for 10 minutes just looking at her with the 32mm. Then I tried each eyepiece, 21mm, 17mm and 9mm and each eyepiece with the barlow. Might as well test out everything while I'm here.

The best view was with the 17mm Baader Planetarium Hyperion. The different bands were clearly visible but there wasn't alot of color. I guess this is where the filters come into play. The 9mm barlowed did give more detailed view but my inexperience with moving a dob had that planet dancing all over the place. The reversed movement is going to take some getting used to. Definitely not like the binos on a alt/az tripod.

By this time it's about an hour from sunrise and I haven't even tried any DSO's. Since I'm not yet familiar with constellations that are up I needed my charts, which of course I left inside the house. Good thing I didn't drive to an observing site.

After looking though the charts I find Scorpius is in the low southern sky. I slewed the scope between Antares and Al Niyat and moved it down about 1 degree, I'm lovin' this Telrad. I looked in the eyepiece expecting to see a faint fuzzy but instead I'm greeted with a bright tight grouping of stars. It's hard to describe the difference from viewing with binoculars and viewing with a 10" reflector with other than WOW! There so much more detail, the stars are bright and crisp, it's just a better experience. By the way, the tight grouping of stars was M4.

The next target was midway between Antares and Acrab, which is M80. It wasn't as bright and crisp as M4 but it was still impressive. If I was lucky on a good night and averted vision I might have seen it with my binos. But that's not a problem anymore.

It didn't see alot for my first time with this scope, but quality will always be over quantity.

That's it. Thanks for reading. Clear skies!

Great report Glad you got to go out with it last night - funny thing is I almost set my alarm for 4am but it was so cloudy at midnight I decided to wait for tonight. I did find the AZ movement on the scope to be a bit stiff so I guess I will work on that today too. I hope I have as enjoyable first night as you did!

Congratulations on a new scope and a great post. You are not going to believe the difference between your binos and the 10" aperature on all the objects you're used to viewing. My neighbor got a Z10 a few months ago after using a 3" (80mm) Meade refractor for a year. It was fun to watch him compare the two and I was very impressed with the views in the Z. What I like to do is use my binoculars along-side my dob. I scan for fuzzies with the binos then see what it looks like in the scope. You're in for a lot of fun and brand new views!

Nice report and congrats on the new scope, once you get the hang of moving the scope for viewing you won't even think about it any more. The Telrad makes things go alot easier at finding thing's,,, at least it did for me.

I knew I would not have to call you this morning. I started to call but I rolled over and when back to sleep when the alarm went off. Tonight will be good except the moon will blind you. Have fun and tell me all about it Monday. (to the crowd, we work in side by side desks)

Right on, I am glad you made it out for some early morning viewing. Wait till you get Saturn in the EP, your jaw will leave a dent in the ground! I found the 13mm Hyperion hits a sweet spot with my Z10, even with either or both tuning rings installed. It gives some very crystal clear views!

Wobrack - how smooth is the az (lateral) motion on your base? Mine is pretty stiff, even after installing "Magic Sliders" that others have suggested. I had a lot of problems getting objects centered in the view - the resistance requierd me to give it a nudge and then it slid too far. I'm going to try some automotive wax on the sliders to see if that helps, but I think it's going to need more.

I did get mine out for first light tonight, but conditions were pretty bad. Cloudy, windy, turbulent air, a full moon and light from the neighbors all made it tough. I was determined to get it in use short of anything but rain however We got some good views of Saturn, a bit washed out with all the light, but pretty still. Looked at a few doubles, and found M44 just to see if it was possible in these conditions. It was far to bright to make out much but I was really happy that I found it almost immediately with the Telrad, not being able to see it naked eye. As it happens, M44 is right at 4 degrees from the center star of Cancer, heading towards Pollux. Putting the outer ring of the Telrad on that star put M44 just on the edge of the view in the 32mm.

Big plans the next two weekends for me, getting out to dark skies to push this thing some. I was in Ft Mill tonight, not far from you, so I'm guessing you had similar conditions.

Wrathchild,
The azimuth movement is good when moving from one object to the next, but it is terrible while tracking an object like Saturn. The only mod I've done so far was replacing the center base bolt/nut with clevis bolt/pin. That helped with general movement but not so much with tracking. It still sticks when attempting small movements.


Second Light
Last night was my first time ever viewing Saturn and it was awesome. Started off the 17mm Hyperion, don't have the 13mm yet, and as it came into focus I just slowly mouthed the word W O W. So I got brave went for the 9mm w/barlow. Saturn didn't look so small but know I understand how the atmoshpere effects your view (Seeing).

The Beehive (M44) looks even more impressive with a telescope versus binos. It took a while to find because the moon was washing out most of the stars in Cancer. The best few was with the 21mm Hyperion. I totally forgot about using 32mm that came with the scope. But it'll still be there next time.

I ended the evening with views of the moon. Started with 17mm Hyperion and finished with the 9mm w/barlow. The detail was outstanding.


I definitely need to get a stool of some sort because the lawn chair I'm using just doesn't cut it. Anything above about 65-70 degrees and I have to stand-up and bend down to view the eyepiece. My aging back can't take much of that.
