EvoFF - مصحح تسطيح المجال لتلسكوب SkyWatcher EvoGuide 50ED

Set up took only a few minutes, and the difference in star shapes from corner to corner is immediately obvious. My 50ED is now producing crisp, round stars across the entire frame, which makes processing a breeze.

Switched from a standard T-ring to this for my DSLR and the corners are finally sharp across the whole frame. The 55mm backfocus was exactly what I needed without extra spacers.

I’d been struggling with coma in my wide-field shots, but the 55mm backfocus really flattened things out nicely. Works well with my DSLR for crisp stars corner to corner. Only knock is the adapter felt a bit snug at first, but it’s fine once threaded on.
