About this item

  • Include:Dew Shield Cap Cover Bahtinov Mask Spike Diffraction 4 veins Spike Diffraction 6 veins.Bahtinov mask and divergence spikes can only be connected to the lens through the dew cover in the assembly, and cannot be directly installed on the lens.
  • Bakhtinov mask can make the light received by the lens form three rays on the lens. You only need to adjust your focus ring so that these three rays cross at one point, and perfect focus will be formed.
  • Diffraction Spike Mask Slide is used for cool fun effects on bright stars. Simply slide it in, then watch as stars get cool spikes.
  • You recieve the MASK DELUXE Dust Cover, which allows you to protect the optics of the Seestar S50. And yes, you can even power down the Seestar with the Dust Cover installed!
  • A rain cover can prevent your telescope optical system from fogging first. and the design of internal frosting can reduce the refraction of some light, allowing you to observe for hours with perfect angle.
  • High quality materials:Our products are customized by ABS, which are very firm, elastic to temperature changes, difficult to absorb moisture, helpful to maintain the dryness and stability of products, high surface gloss and good surface texture.

This set was of little value. It is not made very well and does not provide a threaded filter adapter for the SeeStar S50. I must have misread the information about this kit, because I thought the kit provided a filter screen adapter feature. The provided masks seem cheaply made are are not very precise, just bands of plastic in the adapter rings. Only the lens cap cover is useful. Not something I would buy again.

We have a Seestar S50 for astrophotography, and this dew shield fits its lens well. It has a matted finish which helps to avoid reflections when filming, and it helps to prevent stray light from entering. It also helps to prevent dew from forming on the lens, as well as avoiding stray dust or debris when outside. We bought this because of the dew that forms on our Colorado nights. Overall, it does what we need it to do. 5 stars for that.

For the price it's a decent accessory. A thin film I guess of rubber epoxy would create a tighter snug fit for the dust cover but whatever also get a leveler

Pricey for just being cheap plastic. I’ll keep it, but it’s a disappointing product.

The dew shield fits snug and the attachments fit snug into that. BUT the lens cap doesn’t fit the Seestar and will fall out when closing. Once closed, it stays put due to the base so I guess it’s serving its purpose. 5 stars for the dew shield and attachments, 0 for the lens cap.

Fit our S50 with no issues. Not too snug and not loose. The tube is durable and the star attachments are made with 3D print filament and can be fragile, so take care. The dust cap was a little loose but it stayed on when I closed the arm. So, maybe it's okay.

Well-made, all pieces fit very well except for one. The dust cap (it fits very loose to where it falls off if the lens points down in any way or i would have given 5 stars
