Filter Tilt mount available soon from RAF camera

[christian viladrich]

Hi,

For information, a tilt mount will be available soon from RAF camera. Here is a picture of the prototype :

The final version will be anodized and have other type of knobs.

There is a M42x0.75 mm thread on both sides, the holder is for 1"1/4 filter. The back focus is 20 mm.

The tilt can be secure thanks to the knob attached on the filter holder.

I have ordered three of them for Ca K imaging ;-)

Clear skies,

Christian

Thats great news, thanks.

Most excellent news!

Great! Thanks for the information.

In the mean time, I finished my home made version.

When can i order the new Tilt-adapter from RAF, or can i already do it ? Does anybody know that ? Best regards, Bengt

Hi Bengt,

Just send a send to Raf :

I hope to have mine (I've ordered three units) in a few weeks (including delivery delay).

[blindqvist]

Great, thank you so much. Take care.

By the way, what would you say. This unit mounted on a Quark with a second BandPass Filter, like an 25mm 1nm Alluxa. A dumb idea? A DoubleStack BF mod.

[christian viladrich]

I don't think a double stack BF will help. I've done some simulations to test the idea some times ago, but 1 nm is way too large. It makes no difference.

There is some benefits of double-stacking starting at about 2 A filter (and of course below). So, practically it means double stacking with a Lunt 40 (which seems quite difficult to get ...).

Fingers crossed there will be more stock soon.

[marktownley]

Back in stock people!

[marktownley]

Mine arrived today. Took just under 10 days to get to me. Not tried it yet, but from a mechanical perspective i'm impressed.

Looks very impressive Mark, looking forward to your results.

Tilting hardcoated ultra narrowband filters is the future : )

Indeed.

(but not more than about a degree or so ideally)

Single cavity ones yes, 2 and more cavity ones quite more without significant losses.

I got to test mine under the sun today:

Couple of points, there is a significant light leak in the slot the brass thumbsrew sits in, I sealed with black electrical tape, I guess a felt washer would work also.

Even with tightening the allen bolts on the hinge the movement is quite coarse and difficult to be precise with.

My conclusion is that it is excellent to tilt filters with, however to have an accurate way of fine tuning the tilt of filters a skybender is a far better option. That being said this has a purpose and i'm pleased with my purchase.

What is this filter tilt holder/mount used for?

How is it different than other ones available such as from ZWO and Daystar?

It is used for tilting ultra narrowband CaK filters to get them on band or throw reflections.

The tilters from ZWo and Daystar are used to tilt the camera not the filter. Completely different thing.

Ah ok, thanks

Hi!
Thank you everyone for the product idea, support and feedback!
We are working on the new version of the tilter.
It will have just a turning knob without that slot caused light leaks.
Hope it will be more convenient than the first version.
There will be some play that we can't avoid yet, but I'm still thinking about this.
The new version will be finished by the end of May or beginning of June, most probably.
Thank you.
Rafael.

[marktownley]

Great news, keep us updated!

Rafael
Is there any chance that you could make something that works like the skybender?

[RafCamera]

Hi David.
What happened with the Sky Bender inventor (Apollo Lasky)?
His design appears to be more convenient than ours. I thought about pin driven tilting as well (and maybe even a micrometer-type mechanism for fine tuning), but springs and pins are our pain, to be honest. I try to avoid them whenever this is possible :-)
If Apollo is still in business, it is better to support him with this project.
Thank you.
Raf.

[DavidP]

Apollo made only a few of these some years ago. He never sold them, but just made them to be tested. He Is no longer on Solarchat,but I don’t think he has any interest in making these anymore.
I totally agree about the use of springs. A flat spring might be less problematic Or perhaps some other way too introduce tension.
I know a number of people sure would love it if you made something like this.

[RafCamera]

This will be the third version if we ever make it :-)
Now, we need to test the second version. I expect to get it finished in about a week.

Hi Raf,
Could you expand a little bit on "Tilt control changed from pull/push type to a thumbscrew turn type."
Do you mean that rotating the thumbscrew (arround its symetrical axis) induces a rotation (= tilt) of the filer holder ?
So the thumbscrew position keeps the same ?
Thanks !
Christian

Hi Christian.
Yes.
