Greetings from Switzerland

[GuillaumeC]

Hi everybody

My name is Guillaume, 32 years old and I am Swiss.
I speak French and must be content to go through "Google Translate" to communicate with you.

I practice astronomy since very young (when I was 10 years old) and astrophoto since 2013.
It will be said that I have actually been able to practice astrophoto since the end of 2016 because of my move which is the ideal place to practice this passion.

I work mainly with
Televue 76 and its focal length reducer x0.8
CCD Zwo ASI 1600 and its filter wheel with filter Astronomik
Orion Starshoot set for autoguiding and PHD 2
And a Skywatcher NEQ6 Pro Synscan.

For now, the main reason for my registration is that I just acquired a BORG 55 fl 3.6 and can not do the Back Focus.
I spotted a person who owns the same set.
I also think that other people can help me.

Excellent day to you

According to this site the optimal distance is 60mm, which is a bit different to the standard 55mm obtained with the extension tubes that come with the 1600, so I am guessing you would need to get an extra 5mm T2 extension tube to add between the camera and the scope.

Enjoy the journey.

Hello
Thank you all for your welcome messages.

@Demonperformer
Indeed, Borg asks for a backfokus of 60mm. There is a ring, supplied with, of 5mm and my salesman machined me a spare part of telescope / Wheel with filter and CCD to the good dimension.

The problem can come from the "Astronomik" filters 1mm thick. I have to test it next night.

The question I ask myself:
Since where do you measure the backfocus?

Hello Guillaume, welcome to the community, you would get a better response posting

your question in the relevant forum, the imaging sections would be best, you should get 

your answer faster.
