Henry has done it again !

#1

Post by Don Quixote » Thu Oct 24, 2019 3:15 am

This morning My friend Henry and his lovely wife stopped by my home on their way to a luncheon date. Mrs. Henkmeister has known my mother for years and wanted to make a visit.
At 11:30 they arrived and the two ladies settled into a chatty visit while Henry and I huddled to our own chat. 😊
Henry had with him a largish box.
Inside this largish box was a 6 inch f/5 newtonian, Bresser 150S.
Now I have another toy to explore and compare with my other toys. I plan on a side by side on the SW AZ/EQ mount with my AR 152 frac. This should be an interesting conserving session.
I will report back to you all.

P.S.
As per my usual anatomical interest in all things mechanical I have completely dissected this new tool and overhauled the 10/1 crayford focuser. It is as smooth as silk!
Unfortunately the sky is overecast tonight or I would be out there now. 😊

After a quick overhaul of the crayford focused I slipped out into the drive to find an open hole in the sky. 😊
I found one !

Seeing and transparency were very poor, but I was able to get first light.

I expected some coma at the edge if the field. There was no coma that I could discern.

I used my docter 12.5 with is wide fov. Stars were pinpoints across the field, edge to edge.
I did not expect this. I am very pleased.

This is a very light weight and "short" six inches. It is light enough I may be able to mount it on my binocular tripod. Will see about that.
I had it on the LXD mount and I can see that the SW in alt/az mode may be a better fit.

I also plan a velvet flocking for this tube.
After overhauling the focuser recollimating was quik.
Very pleased.

Can't wait to point this at some galaxies. 😊

Marcus, better in the hands of a visual expert than in the dustbin of my storage garage. I hope it ends up performing beyond your wildest imagination. With little to no coma in an f/5 Newtonian that's a real achievement on the part of the opticians. Must be righteously parabolized for both visual and AP. I know the few frames I shot through that tube last year before putting it in storage showed very little coma out to the edges or any other optical "defects."

Ok.
Question.
Is it possible that the 3 inches of extension I have to put on the focuser could have something to do with this apparent lack of coma in visual observing with this Newtonian?

Anyone?

Yes, but "front end"? By now I should be able to identify the ends on a Newt. :lol:

Hi Mark,

Beautiful acquisition! I currently own two 150/750mm Newts - the StarBlast 6 on a table top Dob mount and the Celestron Omni XLT 150 on a CG-4 mount. Sadly, I've not tested them out on the night skies yet - looking forward to hearing further reports with your new 6" F/5.

Fortunately, I picked up the longer version of the Bresser 150S OTA, the 150L (focal length of 1200mm or F/8), last year. This size of OTA is no longer readily available here as a standalone OTA, much less mounted on an EQ - only on a Dobsonian. Like the two aforementioned scopes, I've not unleased this scope on the heavens yet.
Scopes: Reflectors, refractors, and 1 catadioptric. Ranging in aperture from 50mm to 150mm.

Thank you, Terry.
I am headed out right now. First light at my best dark site.
I have it on my LXD75 mount.
I know that I will have to figure out the balance aspect on this EQ mount.

I will post my report in the morning.😊
