Solomark Universal Cell Phone Adapter Mount

Recently while using the Daystar Quark to view the sun in H-alpha, I thought it would be great to try and capture a quick image of the sun with my iPhone. Unfortunately the attempts at trying to do this did not go very well, as my hands are not steady enough to do this. Hence I thought it would be worth looking for an adapter to mount the iPhone (or any other phone) to the eyepiece to quickly capture the sun via video or quick photo snap. The research led me to get the Solomark Universal Cell Phone Adapter mount.

The reasons for getting this adapter were:

  1. The dimensions will allow me to use this with the eyepieces I have (Televue 25mm Plossl and Televue 32mm Plossl) – the adapter is said to work with eyepieces, digiscope or binoculars with diameter of 28 – 47mm).
  2. This is said to work with the iPhone 6 plus unlike many other adapters – it will work with smartphones between 54 – 90mm in width.
  3. The price was reasonable at £20.55, and much cheaper than many other adapters available.

First impressions is that the adapter is well constructed and sturdy. The grip is strong enough to grip the eyepiece and smartphone well, which is extremely important.

And as you can see, it fits well on the Televue 25mm Plossl,TV 32mm Plossl and even with the Baader 24mm Hyperion 2″ eyepiece, although it just about fits on the Baader eyepiece.

The presence of a tripod mount can be very helpful if using it with a pair of small binoculars.

As can be seen there is vignetting of the image, although I do not have a chance to see what it actually looks like mounted on a telescope, as this could be better or worse. But it looks like the center of the image can be captured well.

The phone mount has enough extension to grip my iPhone 6 plus (and more, so should be fine even with a case on). The extension to get the eyepiece to be centered onto the camera is at its maximum with the Televue 25mm Plossl,but definitely was not an issue with larger lenses such as the TV 32mm Plossl. This is because I had to ensure the rubber grip holding the phone avoided the volume down button, otherwise it will be constantly pressing on it. Otherwise it would have given even more latitude for positioning the phone; one option is to cut off a little of the rubber grip so it avoids the volume button.

As the weather is wet, I have not had a chance to use it outside (particularly with the Daystar Quark). I will post this when I have had a chance to use it.

Impressions:

The Solomark Universal Cell Phone Adapter Mount is well constructed, grips both the eyepiece and phone well, well priced and has enough extension to work with my equipment. But from handling it and first impressions, I would definitely recommend it. But with the iPhone 6 plus and eyepieces smaller than the Televue 25mm Plossl, there may be an issue centering it onto the iPhone camera due to the need to avoid the rubber grips pressing down on the volume button.
