Patio (home)

Skywatcher Esprit 120ED

Warm

21.00 - 01.00

 

Cannot remember the last time I done any observing while wearing shorts and a T shirt. In fact it's been such a long time since I've been out. Decided to work through Sissy Haas book on double stars, and by doing so used my newly aquired 4mm Clave' plossl.

 

Leo

  

Alpha Leo - 1.4/8.2 - 176" - Very easy split - 12mm Clave - x70 mag - White/Grey

Iota leo - 4.1/11 - 1.7" - Sissy Haas book says B is 6.7mag, while CduC says it is 11 mag. I tend to believe CduC as this was pretty hard and only glimpsed - 4mm Clave - x210 mag - Yellow/Grey

Sounds a good night Mick, was this using the new mount?

 

Ron

[Doc]

It was indeed Ron and it was brilliant, so sturdy it's unreal.

[Daz Type-R]

Nice haul you got there Mick.

 

 

[Guest]

It was a shame I couldn't stay up all night. I am using some borrowed bins and potted M36, 7, 8 in Auriga with the Moon a few degrees away. I hope all board members got something last night. I was one not to miss.

[Doc]

It was indeed a good night Phil, hopefully tonight will be just as good.

[Tweedledee]

Great report Mick. That 4mm Clave is splitting some really tight ones. ?

[tuckstar]

Nice report Mick. Glad you managed to find the a lower mm Clavè.
