Newton Ring Eradication

#1

Post by CarlGreen »

Hello everyone, (Admin, if this is not in correct forum please feel free to move to appropriate one)
I am having problems with Newton Rings on both my Skyris 132m and a ZWO Asi120MM Mini.
(On a Lunt60 THa with B1200 Diagonal)
I have decided to purchase a tilt adjuster to try to eradicate them.
I have looked at the ZWO one and the Daystar Interference Eliminator.
I know there is a large price difference, but would it be worth the extra money getting the Daystar?
(I like the simplicity of the Daystar one, looks quite easy to adjust)
Does anyone have any experience of either (or both) of these?
Any thoughts and suggestions apprecaited

Hi,

I haven't used either, so can't comment on the differences between the two :) I will point out a couple of things though...

There are some cameras that have a built in tilt adapater - similar to the ZWO one with 3 adjustment bolts and 3 lock blots. Player One cameras often have this feature. I guess it must work well enough to be installed on cameras...

Don't foget to check the thickness of both options (with any necessary adaptors) - how much further will they push back the camera, and will you still be able to reach focus with them fitted...

cheers,

Robin

Thanks Robin, I did think about a Player one with built in Tilt, but thought I might try the less expensive option first. (False Economy as no doubt I will end up getting a Player One and then I will have a Tilt Adapter I dont need! :shock: :D )

Hi,

yep, astronomy is always like that... I must admit that given the difference in price, I'd be trying the cheaper one first...

cheers,

Robin

Hi
Worth adding to the equation is the Player One Tilt Adapter,very easy to tilt with two screws.
The Daystar one is pretty good just remember to add some tape around it to cut and light leaks, the ZWO one is similar to one marketed by First Light Optics under their Astro Essentials range and comes in m42 and m48 fittings,think with some larger cameras they need adjusting without it attached.

Another option if you have the available backfocus is an ADC, especially since many of us probably already have one for planetary imaging. This works really well for me, and I find less prone to light leaks and mechanical wobbles. Does also allow you to easily adjust the direction of tilt to find the minimum amount needed to eliminate the rings.
