a better scope for less than half the price............
i used to use 8inch Schmidt-Cassegrain to astrophotograph nebulas with a friend , then i decided to get my own telescope and i ordered the sv502 102mm with the reducer to start my astrophotography journey , i was worried from the chromatic operations since it is a doublet but here is my experience with it :
- the stars are nice and round on the corners of the image
- there is no blue stars when using dual narrow band filter or even multi band filters using a color camera
- the images that produces is very sharp which is spuriously sharper then the 8inch Schmidt-Cassegrain while this scope cost less then half the price of the 8inch
- comes with dew sheild bult-in which is huge plus.
- i was able to capture the horsehead nebula, the rosette nebula and andromeda in great details
in conclusion i believe i made the right choice going with this scope and i am very happy with the images i get with it

SVBony503 102ed
Great telescope with all required astrophotography accessories for cheap price.
With field flattener you barely see blue halo around stars for this doublet telescope.

Features
- 1. The appearance of the telescope is baked with high-end fine-grained paint, with exquisite appearance and delicate feel
- 2. The objective lens features an S-FPL51 extra-low dispersion glass ED element, which eliminates chromatic aberration. This results in the best color correction for an ED doublet lens
- 3. The lens adopts optical processing and low polishing technology, which is carefully carved
- 4. The deceleration ratio of the two-speed 2'' toothed focusing seat is 1:10, which makes it easy to achieve accurate focus
