Sounds like a nice option.

Retrofitting a corrector may not be enough for imaging as the secondary mirror size has to be enough to create a big enough imaging circle that is fully corrected. Then again Tak are awesome as imaging experts so I am sure they will come up with the goods.

Orion Optics UK though already make corrected Dall Krikhams with carbon fibre tubes, with triplet correctors, with fan controls, with design from scratch to be a great imaging scope as well as great visually things Mewlons don't have as standard.

Planewave also makes a 12.5 inch corrected Dall Kirkham for US$9995 which has carbon fibre tube, heavy duty focuser, 52mm corrected imaging circle, lightish weight, lots of fabulous images on the net and about half the price for the Mewlon 300. So the Tak scope is hard to justify when it doesn't have a carbon fibre tube (extra upgrade, which means focus will go off over temperature shifts to some degree as well as heavier), no fans (means thermal layers on mirrors unhandled and tube currents more likely) no corrector currently means no good for imaging, Mewlon no doubt is very heavy placing a strain on the mount so you may need a heavier duty mount.

Tak's Mewlons are really yesterday's design and were great at the time but the market has moved on and now they are overpriced, heavy and lack the versatility of the modern corrected Dall Kirkham.

The Mewlon 210 etc is still unique though as corrected Dall Kirkhams are usually 12.5 inches up. Orion Optics UK are planning an 8 inch but not yet.
