AR2713 250mm RCT

Post by Carbon60 » Tue Jun 19, 2018 7:57 am

Just a quick one from this morning before work and before the clouds rolled in (especially right in the line of sight!)

Not ideal through some haze and with poor seeing for much of the time.

Thanks for looking.

Before work!! wow! what a great start to the day :bow :bow :hamster: you are very lucky to see this AR, I was hoping at the weekend but no chance, by this weekend it will have rotated around a bit but I can hope for some Sun :) I must ask you some questions about your filter when I get the chance.

Hi, Stu

Great view, with smooth processing.

Did you use your Lunt 35 etalon for this or another?

Excellent results given the conditions, Stu. That AR is not easy to image, for some reason.

Excellent image Stu. I was out this morning, but missed the better seeing.
Best wishes,

Stu:
Very nice smooth image with your big scope, I still have not been able to use my 10" Aries ERF with the 10" f/20 Maksutov.
Looks like it will take at least 2 months, because our raining season has started.
Best wishes,
Eric.

Many thanks, everyone.

Lou, the whole Lunt35 was used for this image (etalon and refocusing lens) together with a BF15.

Eric, sorry to hear that progress remains slow. It took me a few months to get everything manufactured before I could get to first light. Good luck.
