About this product

Model:  stellamira_2inch_1x_ff_m48
Part Number:  K1.0X-DBU03

This useful non-reducing Field Flattener enables DSLR astrophotography with most f/5-f/7 refractor telescopes. 

It is optimised for DSLR cameras and telescopes with f/5-f/7 focal ratios.

It will also work well with telescope focal lengths narrowly outside this optimised f/range if using an astronomy camera with a smaller sensor. 

Identical to our M42 model but features an integral M48 adaptor thread that can be swapped for an optional M42 adapter. 

Fully multi-coated optics fitted into a CNC machined body with a gloss black anodised finish. 


  • No change to the telescope focal length.
  • Suitable for focal ratios around f/5 - f/7.
  • High-quality, fully multi-coated optics.
  • Integrated M48 camera thread (can be replaced with an optional T / M42 adapter).
  • CNC machined body with hard, gloss, black anodised finish.
  • The 2" nosepiece is tapered for safety and accepts 2" astronomy filters.
  • Requires 55mm back focus

Starfiled 102 ED

This works really well with a Starfield 102 ED and being able to hold a 2 inch filter is a useful extra bonus.

Used with Stellamira 80mm F6.25 for photography at the required 55mm backspacing + Optolong L-Pro + modified Sony Nex-5N does exactly what it is meant to at a most wonderful price!

Stella Mira field flattener

Stunning and very well built.
I got this to go with the Stella Mira 90mm for extra targets. Simply screws onto the scope with the spacers supplied with your camera, switching one equal to my filter drawer and add 533mc bring to focus and perfect performance. Beautiful flat field and crisp sharp stars all over. Single 2min sub on Andromeda fill the field diagonally. Stunning capture.
Thanks FLO for top quality gear and top quality service.

Field Flattener

I've only had the opportunity to use this once so far, it appears well manufactured and fits the end of my Startravel 120T focuser. The 2" push fit makes attaching the CCD to the OTA a lot easier than having previously had to screw on the imaging train to the OTA. Intial images show that there is clearer focus at the edge of the FOV so I guess it is doing what it is supposed to be doing.
