ASA/Keller 400
-> DeepSky, Sun Bright Field, Moon, Planets​​​​​​​​​​​​​​

P Keller-ASA 400 (3600mm/ 1200mm) f9/f3 ............................ LOMO Mirror Sital Glass (f9 Secondary Flattener/ f3 Primary Corrector)

​​​​​​​Orion ED80 (partial conversion)
-> Auto-Guiding DeepSky

Orion ED 80 (600mm) f7,5 ..............................................................(shortened tube), Flip Mirror, Guider Okular, SBIG Guide Head adapter and laser quick finder
Skywatcher Evostar ED150 (total conversion)
-> Sun H-alpha
​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​
Due to the good correction of the ED Glass element, around the H-alpha red wavelength 656nm, it is used in my observatory as a H-alpha telescope. It was rebuilt for this purpose.

Modified junction D-ERF/ED150: the original black tissue tape was replaced by thick aluminium tape and black PVC tape. This small step in diameter at the front prevents an accidentally slipping of the three point fixed D-ERF filter.

The selfmade screw cap: the dew cap was shortened (55mm) and permanently fixed to the original end cap. A good protection of the front lens during storage

Balancing Telescope
-> DeepSky Setup versus Projection SetUps
​​​​​​​

image-12356273-Telscope_ALLINONE_Hoch-aab32.w640.jpg
1.)
When the SetUp is used for DeepSky fotographie, the SBIG Camera/ Rotator/ f9 Korrektor is mounted to the ASA focuser at the backsite of ASA400.
 
​​​​​​​The backsite counterweights are taken off to balance this heavy change.

2.)
When the SetUp is used for Projection fotographie (Moon, Planets, Sun bright field), the ASICamera/ FFC/ Rotator is mounted to the ASA focuser at the backsite of ASA400.

3.)
For the Telezentric fotographie (Sun H-alpha) the  ASICamera/ Telezentric/ H-alpha Filter  SetUp is mounted to the Feathertouch focuser of the ED150 refractor.  

In case of 2.) and 3.)  The backsite counterweights are mounted to the rod and moved to balance the various projection SetUp weights

The Counterweigt at the Alt-AD7 Mount in the uppermost position is minimally slided to finetune the two SetUp's Deepsky versus Projection.
