Busy upgrading the MiniSHG to the 2nd generation Sol'Ex 125mm fl lenses.
Adjustments continue......but the early Ha results look VERY promising.
Onward and Upward
Thanks guys!
The performance definitely seems to reflect the quality of the optics used.
The jump from a $2 Surplus Shed achromat to a $75 Shelyak "custom designed" achromat, although costly, showed immediately an improved outcome.
Re-building the collimator and testing the focus/ infinity focus on the slit plate, is a bit fiddly, but I'm sure will be worth the effort.
WOW Ken! that full disc looks amazing and I guess it's only going to get better and better from here, both in terms of the Sun waking up and your MiniSHG improvements. Bravo!
