Hi Steve..

Did you use your Esprit120 to see Neptune?

I ask because that is the scope I have.  And perhaps I might be able to do the same.

Also - how can you be sure that is Neptune.  And not just another star?  

Just wondering..

Hi Ted

Plotted it with CdC and also did a plate solve. Its a spectrum I`m familiar with also ,I know what you mean though .Astroart puts it at mag 7.20.

Love my Espirit BTW.

Regards

Steve

Wow thats cool!

I'm desperate to do some spectroscopy soon, may I ask what grating you use? I was looking at the Star Analyser 100. 

Also, is that Triton to the (apparent) left of Neptune? A quick look on Stellarium makes me think it is. 

Thanks,

Dan

Hi Dan

I did wonder that myself and was going to check later,I`ve no idea what mag Triton would be, there is a small star near Neptune from the UCAC4 catalogue so I`d have to rule that out first!. I use the Star Analyser also, its an excellent introduction into the spectro world

Cheers
