perfect fit, good quality & i prefer this to the supplied one, it gives much sharper images.

A very good product which produces very clear images of sunspots and solar features. A great improvement on the standard SeeStar solar filter.

I wanted a white light filter as although the original Seestar is OK, I prefer natural light colour. This filter is well made and it's very reasonably priced.

I bought the Baader filter from FLO to see if it performs better than the version supplied with the Seestar. I take a lot of solar disc record shots with the Seestar, and thought it was worth £25 to find out if I'm using the best option.

The Baader filter is supplied in a case with instructions and the mount is 3D printed to a reasonable standard.
At least one person has reported that the Baader version is too shallow in depth and they thought it was less secure when mounted over the lens. My version at least didn't have this problem, and seemed every bit as secure as the Seestar version.

I was going to test them early in the morning when the seeing is generally better, but it had to wait until well into the afternoon. Storm Lilian was passing through through with severe gusts which had brought down two trees blocking roads not too far away.

The tests took place just after 4pm. I had decided to take twenty pics with each filter in turn, starting with the Baader. I took the pics every couple of seconds or so. There were some pauses to wait for the occassional gust from the departing Lilian to die down.

When back indoors I intended to select the best pic taken with each filter and compare them. In truth, the seeing had been rather constant ( about average for my location) , so there was little difference between all of those taken with the Seestar filter on one hand, and the same for all those taken with the Baader on the other hand.

However, the Baader pics were generally sharper than those with the Seestar. Also the Baader pics showed the surface texture and the faculae near the limb better as well, and there were with some small pores which didn't show up with the Seesrar filter..

CONCLUSION.

If you want the best solar detail, the Baader Solar filter is worth paying the extra for.

I like to use a Starizona solar finder along with the filter; the Starizona finder is mounted on a 1.7mm thick ring which fits between the solar filter and the front opening of the Seestar.
I recommend that the mounting ring on the Astro Essentials solar filter be extended another 1.7 or 2.0 mm, which would make the fit of the filter into the Seestar more secure when using a solar finder.

Otherwise the filter, which uses Baader film, works well and provides better resolution than the stock filter supplied with the Seestar. I would give this five stars if the mounting ring were extended; otherwise I use blue painters tape to secure the Astro Essentials filter to the Seestar as a precaution to prevent the filter from falling off when the Seestar is pointed at the sun, which would damage the sensor chip.

I was wonderfully surprised at the brilliant design of this filter and case. Makes for easy removal out of the case and onto the Seestar without worrying about getting my fingerprints onto the Seestar. The detail this filter brings out is surprisingly better quality than the Seestar's filter....which surprised me. The Baader 5.0 solar filter brings out stunning detail even before I finish processing the image. The final result is quite stunning.

Arrived on time and works a treat.

This filter has improved the contrast when looking a Sunspots, compared with the solar filter supplied with the S50.
So although a little expensive, it's well worth purchasing.
First class service from FLO as usual.

Found the sun straight away and seemed to be clearer than the orange one, that came with the Seestar.

I am thrilled with the new Baader solar filter kit. Superior in all ways to the filter included with the S50. Get it - a must have for all S50 owners.
