Tilt adapter question

[ffellah]

Hello everybody and Happy New Year. What are the tilt adapter options for a Flir Grasshopper 3 camera ? Is there any way to adapt/connect the ZWO tilt adapter to the Grasshopper ? Thank you in advance for your help.

Hi Franco,

I just saw in the page that the camera has a C-Mount thread and that is 1" 32tpi.

Being that the case you need an adapter from T2 thread = M42x0.75 to C-Mount 1"-32tpi.

Something like the one below

https://www.amazon.com/0-75mm-Thread-Mo ... 952&sr=8-4

Camera is female C-Mount so the male part fits in there and the Tilt adapter from ZWO has a M42 to M42 male to male adapter and so the female part of the ZWO adapter fits into the amazon adapter.

One more

and the question still is how do you connect the Grasshopper now to your telescope ?

Do you use a 1.25" nose piece ? If yes then you need to order the nose piece from ZWO which has a T2 thread.

You will possibly need another adapter from T2 to the part of the telescope ...

Hi Franco...

Happy New Year to you and family as well.

The links that Rainer sent will do the job. I bought another version of the C-to-T adapter many years ago for mate the Daystar tilt adjuster to my Grasshopper Express. You will need the adapter to get the 1.25" nose-piece on the opposite side as well, but the combo is not expensive and will not take up much focus travel.

Daystar does make a C-mount version of their adjuster which will not require any additional adapters, but it is $175.

Thanks a lot Rainer and Brian. I ordered on Amazon the one on the first link, that was the least expensive. It will most likely do the job: I will keep you posted.

Hi Franco,

Glad I helped you. What about the connection of the Tilter to the scope ?

Diving in here a bit late... I have the Daystar CMount tilter, and I find it good, easier to use than the others i've come across. The only thing I would do differently is I would use their TMount tilter instead; it has a larger clear aperture. I find when I use it with my IMX174 chipped (widescreen) camera I get a bit of subtle vignetting with a lot of tilt. Nothing huge, but it hurts my head knowing it's happening

I have an article on my website you may find of interest https://brierleyhillsolar.blogspot.com/ ... rings.html

Rainer: I should get the adapter on Wednesday, see that all works well, hopefully, and then see the connection to the scope. I have the nose piece of the ZWO174 that I can try out. Then if I sell the ZWO camera, I will get a new nose piece. Mark: thank you for your input and for pointing me to the very interesting article on your site.

Hi Franco,

What are the advantages of the FLIR Grasshopper 3 camera to a ZWO 174MM ?

I'm also a bit late to the party. I have both the Grasshopper and the Zwo tilter. I've never had NRs with the Grasshopper ever, so never tried it with it. So why do you need a tilter for the Grasshopper? The ZWO ASI174, that is a different beast for rings. However, I've still never managed to work out how to use the tilter with the ZWO.

I get NR with my 174 chipped GH3

Hi Alexandra: thank you for your input. I just received the FLIR Grasshopper 3 with the 174 chip a couple of days ago. Due to the season and weather, I do not know when I will be able to try it and see if I need a tilt adapter. But I want to have one that works just in case I need it. Imaging time you know is precious and do not want to find out I need a tilt adapter and then having to wait for delivery, etc. I also have a ZWO178 camera, and may need the adapter for that. This down time is good for me to review the equipment and see what I can upgrade for the next season. I already have the tilt adapter from ZWO that I have been using for the ZWO174 camera regularly. I just needed the C mount adapter to make it work with the FLIR camera.

Oh I see, I forget the Grasshopper comes with many chips. Yes, that 174 sensor is a pain in the but!

Alexandra

[MapleRidge]

Sounds good Franco!

All you basically needed was the adapter to convert the camera C thread to the T thread on the tilt unit.

I think you will really enjoy the 174 chipped camera!

Thank you all for your help

@Rainer: I tried the new Grasshopper 3 with the 174 chip on Saturday. It is definitely faster than the ZWO ASI174. With my i5 Acer laptop 2.2Ghz 8Gb of memory and 500Gb SSD I got right away two runs at 140 and 141 FPS. With the ZWO camera I was getting at best around 100 to maybe 110 FPS. I have not had a chance to compare noise, but so far I am happy with the upgrade. I still think the ZWO ASI174 is an excellent camera and has a great value to performance ratio. BTW, Rainer, the adapter you suggested works perfectly, thank you.
