adapter help needed please?

[assouptro]

Hi sun worshipers!

I have been playing with solar imaging for a year or so and at this time of year it's often the only 'astro fix' i get due to my latitude

I have a quark, which belonged to a solarscout which I have adapted to fit other telescopes and my main imaging camera is a point grey blackfly which has a cs to 1.25 nosepiece but I would like to be able to use a 0.5 focal reducer however my nosepiece is too long to achieve a decent image.

I have been searching the internet to try and find a low profile cs to 1.25 adapter to move my focal reducer closer but I am struggling!

Can anyone suggest a solution?

Many thanks in advance for any help

Maybe somebody can 3D print one for you.

I cut down a standard T2 - 1.25" nosepiece. So I can fit GPCs between my ZWO camera and the Lunt blocking filter.

It might be possible to do the same with a C-mount adapter. Though I am not familiar with them.
The female thread length looks too long on most of the adapters I just looked at online.

No need for a lathe. Wrap neatly across to the desired length with tape first and then hacksaw at the edge of the tape.
File, or sandpaper the end smooth with the medium abrasive paper resting on a flat surface.

The start of the newly cut-off thread needs to be clean and smooth to allow something to be screwed into it.
Never force it to screw in. Or you may cause permanent damage to both threads!

It is vitally important to use a receptacle with a compression band if you shorten any smooth surfaced male fitting adapter.
I always drill and thread my compression band adapters for three clamping thumbscrews 120° part.

What is the point of asking a question and then not bothering to look at the answers or worst still seeing the answer and not acknowledging the three people who offered something up?

That’s really not how SGL works @Freddie. There are a whole range of reasons why @assouptro may not have been able to check back or comment on the thread and it’s always preferable to think the best of people.

Your comment is unnecessary and discourteous, so please don’t post like this again.

He has been back on the site a number of times since the three of us went to the trouble of posting to try and help him out but I take your point that during the time he was on the site he may not have had enough time to check if there was an answer to his own last post. I am sorry that my disappointment was inappropriate and will be more considered in my future replies.

Hi 

I am sorry if I seem ungrateful for the response from anyone who took the time to reply to my enquiry 

I wont go into any personal details here but it has been a tough time for our family.

This is a hobby, albeit an important one, but sometimes life has a way of putting things into perspective.

Thanks again for the replies 

Bryan
