If Nic's sketches are right it's a Celestron C6r on a EQ6 mount. 6" Achromatic refractor I think it's f8 if I remember right.

Great haul there loads of different colours and magnifications well done. 

I had parked the scope last night so started the session without alignment but it was out so did three star Alignment, Arcturus, Vega and Capella much more accurate.

Coma Berenices

Σ 1633  (SAO 0822 54)   yellow/white twins with a hair split.

24 CB   (SAO  1001 60)   Colour here is lovely Yellow and Blue a fine sight.

Σ 1685  (SAO 1003 07)  Slight gap here blueish white and pale green white

32-33 CB  (1003 11) Wide double Haas says grapefruit orange and pearly white I just saw orange and white.

Σ 1639 (0822 93)  this was very tight had to use 6.4mm here. 1.7° split

17 CB  (SAO 0823 30)  Very wide nearly the same colour.

Canes Venatici

Σ 1645  (SAO 0441 87)  twin white stars

α CVn  (SAO 0632 57) Cor Caroli   What a sight truly beautiful large white star with blue/green secondary 

16-17 CVn   (SAO 0633 80)   Very wide white pair of stars

Σ 261  (SAO 0633 96)  Tight Whit/blue stars split with a hair with a 10mm with nothing else in the FOV even at lower powers.

That was my first scope and up to now the only one I have ever caught E and F in the Orion Trapezium with cracking scope. 

Nice haul and I am not Jealous I am really not Jealous that you got the Leo trio not Jealous at all.

A great session there I have not managed to get the 3rd component of Tegmine yet I keep trying though. 

Wow I would love to have your sky I can only see smudges of M81 and M82, Great report and what a haul.

Brilliant Nick Hercules and Lyra are coming over to my best view so I have them to look forward to. I went for Coma Berenices and a few in Canes Venatici last night.

Great report and sketches as usual.

It was Nick and the eyepieces that's why I didn't bother trying and just packed up. The views where getting watery.

Nice report and some excellent binaries. Shame about the dew. I have dewing problems when I use my ED120 at the society observatory and find that an Astrozap dewshield on the end of the stock dewshield does a good job.

 

 

I was thinking about that I have a Astrozap dew strip and another a friend made had them both running last night warm to the touch as well when I was stripping down.

If you have it so you can see the three mirror clips and the secondary is nearly in the middle as I said there will be a slight offset and the black dot is bang in the middle of your centre spot yes.

I use for imaging.... Thats why im wondering if it needs to be perfect

If you read about the 150p as I have said there is a slight offset of the secondary because it is a F5 scope.

Here is another guide this may help better I have just found it.

Set up 9.30pm  Aligned with Arcturus and Regulus. Checked accuracy by going to named star Arcturus as I was going for Bootes quite a bit off so centred it.

Κ Boo   (SAO 0290  46/45)  close double White primary silver secondary.

ί Boo    (SAO  0290  71)  Wide double straw yellow with a dirty white.

δ Boo   (SAO  0645  89) Super wide but plenty of colour lovely yellow with blue secondary.

μ Boo   (SAO  0646  86/87  Supposed to be a splendid sight I could not get the split and the view was terrible back to this in a minute.

S656    (SAO  0830  22)        Both the same magnitude slight variation of colour

Σ 1838   (SAO 1010  09)       Orange twins

Σ 1850   (SAO 0833  74)       Near white twins

2 Coma B  SAO 0821  23)     Tight double only Just split it with 6.4mm

I have not written these in order of observing Before going for Alkalurops I went for Izar  I knew there was something wrong when I could not split this, I thought perhaps mount had moved so tried Coma B and got it.

Went back to Alkalurops because I was looking forward to sketching it but nothing, despite having two dew strips going the front was dewed up so no use carrying on I could have hair dried it but it was only going to come back so gave up with quite a few doubles I had not got.

The 150p has a slight offset so dont worry too much about the secondary looking bang in the middle.

In conjunction with astrobaby`s I use this one.

I did a few in Bootes last night and 1 in Coma Berenices

Great sketches

Great haul there Nick going try those Coma Berenices, great sketches as usual.

The better question is, what the heck happened to its chromed brass barrel?

I was given like that and you don't look a gift horse in the mouth. 

A old Meade zoom 8-24mm

I have 2 televue plossls 11 and 20mm 4.5 TMB  two japan meades 9.7 and 6.3mm 25,15,and 8mm BST' S and numerous others 

Its my goto eyepiece I use it every time I observe it in my opinion better than eyepieces you can pay hundreds of pounds for. 

Brilliant Nick absolutely hissed it down here last night with thunder and lightning I have a list for Auriga so will add those I haven't got thanks. 

I will start on the carbon star list as well. 

How's this does it help. 

I have had this on my hard drive for a while going try post it if this link does not work I will use drop box. Please enjoy.
