Since about a month this telescope is parked in my garage.

It is a Newtonian of 158mm aperture and a focus of 1240mm.

The primary and secondary mirrors were made by David Hind of UK.

The telescope was home-made by my friend Tavi aka Erwin.

Because he have other commitments , I was offered to give it a ride.

I used the oculars seen in the second picture ,from left to right : HM 6mm , Galilei - 50 mm , Galilei - 9mm , Baader Classic 6mm Ortho.

 

This are the double.multiple stars observed on 23rd of December.

All stars were split except 52 Ori where I believe to see a black space between main star and companion but not 100% sure.

I was very pleased to see very well  E and F stars in Trapezium.

Good telescope, excellent optics, reliable mount.

I continued the testing on 26 of December when I made observations of  36 And , Delta Gem , Theta Aur and Eta Ori.

All easely split ,beautiful views.

On 14 of January I targeted 7 Tauri double star.

Unfortunately on the rare occasions when the stars were visible, the sky was hazy but still seeing was not better than 5 to 6 Pickering.

Like with 52 Ori ,also at 7 Tau double star the Hind telescope showed at 248 x the two touching Airy discs but no black space bewteen them.

I have high hopes in  good seeing this telescope will split 0.7'' double stars.

On 18 of January I enjoyed a much too short observing session.

Seeing the clouds coming , I made this two rush observations of Iota Cas and Beta Monocerotis.

Since than, clouds , cold,gray life.

Excellent observations and drawings, Z.!   That scope is a real performer as well.  I very much like the silvery finish!

 

You're using 'old-school' eyepieces, too.   Very historical.

Thank you Dave ,thank you Rich ,thank you Rocco

 

About drawings :I'm doing my best ,but I enjoy much more to actualy do the observation.

I like also the telescope and it proved  the quality of Hind mirrors.

I hope to do more observations ,thank you for your kind words ,I will post the results here.

 

Best regards , Ziridava

Congratulations, Mircea, for the magnificent ride between the stars!

 

I will post soon details and pictures of the making this telescope. The mirrors are from David Hinds, one of the last sets that David sr. has made before retirement. Maybe there are other users on this forum that have mirrors from him, I don't know yet. 

 

The silver look is from the stainless steel tube which I used also to my other telescopes I had built. 

 

Clear sky!

Hello

 

Some more double star observations with the 158 mm F/ 7.85 ''Hind'' telescope bellow.

For objects in Orion I followed Bob King's article on Sky&Telescope site ''Overlooked Wonders in Orion'' :

Propus /Eta Geminorum was suggested by reading Admiral Nanson's ''Star-Splitter'' blog.

All observations were very interesting but the splitting of Propus is now one of my favorite.

Tough nut but doable!
