Home Astro-Imaging Focal Reducers & Flatteners OVL Field Flattener 2 Inch
Superb quality field flattener optimised for DSLR imaging on refractor telescopes with focal ratios of between f/5.5 to f6.0. This unit will also provide much improved results on refractors with focal lengths narrowly outside this optimised focal range.

Using a field flattener greatly improves the usable field for imagers and with todays fast refractors and modern large chips on cameras, this product will enhance your images reducing coma and sharpening stars towards the edge of the field. Threaded for filtersThe flattener has a very useful standard 2" filter thread so light pollution filters can easily be used to help imagers in light polluted areas, this feature is very welcome as otherwise it is often difficult to incorporate filters with a DSLR.Produced from high quality CNC machined aluminium with a gloss black anodised finish.

Worthwhile investment I originally purchased a Skywatcher Evostar 72ed and purchased the flattener separately. Made a real edge to edge difference to my imaging. Not to forget, service was brilliant as always. Stay safe. ?? (25/04/2020) - Merseyside
Thank you This is a really good product all I need now is more clear skies to get out there and photograph more stars! Also thanks to Harrison telescopes for fast turnaround and delivery. (22/12/2019) Gunter - London
Quick delivery. Excellent robust construction. Don't forget to order your appropriate T-mount at the same time if you haven't already got one! (05/05/2017) -
