Solar Warning

  • Only observe the Sun with ISO-certified eye protection, such as the filter found in this EclipSmart product. Never look directly at the Sun with the naked eye or a non-filtered optic. Permanent and irreversible eye damage may result.
  • Never tamper with or remove the permanently placed glass filters in this optic. Doing so is dangerous and will void your warranty.
  • Never leave your optic unsupervised. Make sure an adult who is familiar with its correct operating procedures is with your optic at all times, especially when children are present.
  • Never remove your eye protection when looking directly at the Sun during partial phases of a solar eclipse.

Celestron EclipSmart Solar Filters for Explorer LT & More

Generally great product

The product works as advertised, viewing the eclipse on April 8th it was perfect.

My only complaint is the build quality is a little flimsy. I realize most of the cost is probably the filter itself, but I worry about the screws holding in the thin plastic through repeat use

Eclipsmart solar filter

Great product looked at the sun no problem at all hopefully no clouds on the 8th very happy thank you

Celestron EclipseSmart Solar Filter

I purchased the Celestron EclipseSmart solar filter for my Celestron starsense explorer LT and it worked and fit my telescope perfectly. I ordered it about a week before the October 14th annular solar eclipse and thanks to All-Star Telescope , I received it about two days before the eclipse. I appreciate the speedy delivery from Canada to South Texas!!! I totally recommend this filter and All-Star Telescope!!!

Great service and top quality items

Fast delivery of a top quality solar filter. Excellent service All-Star! Thank you
