First Impressions
The Seestar S30 looks promising. Its small weight, paired with its dual-lens capabilities, is convenient for amateurs and beginners. The USD 349 price tag also makes it affordable for many, especially those who do not wish to burn their pockets and still get the taste of stargazing. Since most features, including star finding and shooting, can be controlled via a smartphone app, the learning curve should not be steep. Complete beginners should be able to handle it without a fuss. The dual lens setup with a wide-angle lens is a welcome change from the S50 version, especially for those interested in daytime landscape photography and wide-field nightscapes.
However, the quality of the lens and overall image quality are things that we have to wait and see. Looking at what the Seestar S50 did, we have high hopes for its younger brother. The 150mm focal length may sound too little for astrophotography, but it will cover most of the popular nebulae with ease. The inbuilt mosaic option will come in handy for larger targets. The solar and lunar imaging capabilities might suffer due to its lower focal length. However, it is a giveaway that many people would welcome in return for added portability.

Where to buy
Seestar S30 is currently available for pre-order from the official website. Also, check your local vendors, including High Point Scientific and FLO, for pre-order. Shipping of the products is supposed to begin in late December.
