Hi all:) ,
After selling my 10" Lx200 and 120mmF5 Refractor. I brought a Bintel Premium 252 Dob. Basically GS-880. With crayford focuser and cooling fan on back of mirror. :D Also a 8x50 erect image finder.
So is this scope a come down:confused: from the Meade?
No way at all:D
After unpacking the scope i thought geez that looks great:cool:
I had to put togeather the mount easy enough, don't know if i would pull it apart again. I don't think the screws would bind to the cheap chip board as well again. Once togeather the mount was very good.:cool2:
The tube was all ready to go, I just added my Rigel quick finder.
So once all togeather I thought that's a very nice unit.:)
How would it go under the Stars:confuse3:
I have used it twice now but I will report on last nights observing.:astron:
After setting up well before dark, took a few pics,(not digital) turned the fan on and went inside for a while.
I like observing in twilight, so Saturn was my first target. Seeing was average to good. 3/5. Never really go better all night.:)
Saturn was very good I used my 8.8mm UWA with No11 filter. Very pleased with the view. Could have used more Mag. I have no higher power eyepiece at this stage.
One point was I found it difficult to get focus with my 12mm Nagler and 8.8UWA in the 2" slot. Had to pull the eyepiece out to much. No problems with the 1.25" slot.
My friend Julian arrived with his box full of Naglers.:clap:
I used many eyepieces from the 31 Nagler down to the 2.5mm Nagler. All came to focus ok.:)
When Julian arrived the Moon and Saturn had gone behind my house. So we focused on Juipter and many DSO's.
The 10" Dob worked very well to excellent, tracked smoothly(better than I had ever thought:D ) We could track Jupiter at 500x No problem. This mount really works well:2thumbs:
The seeing was not really upto a Real Star test but we did one anyway and found the optics of Excellent quality. Any F5 scope at 500x to hold a good view can't be to bad.:P
It's been a while for me to do Star hopping but I haven't lost it. As I hunted down Quasar 3C273. Fist time Julian had seen it and the second for me. My last time was in the 1980's. But someone then showed me. So this was the first time I had hunted it down.:D
So it was a very good night, the scope is great. That crayford focuser is super smooth.
The 31mm Nagler in this scope is:eyepop: as in most scopes:P
I did get a 30mm Super View eyepiece with this scope. All I can say it's ok at best. I'll keep it as a good star hopping eyepiece.
It's not even in the ball park of the Tele Vue's.
:D
So It's not a come down from the Meade, just another good 10" scope that i will use more often. That makes this scope better for me:)
Sorry for the long report:D
:cheers:
