Managed to get these before everything turned foul. I am getting some pretty serious vignetting and coma with those 2 FR's. I suppose it is ok if I stay dead centre and crop. Meade 8" sct, HEQ5, ZWO294 Altair .6 FR and Meade 6.3 FR NGC 5128. 30s

The detail is fantastic Paul But the Vignetting is major Yes, cropping would help

got the lx 90 8" out again last night. Combined the zwo 224 with the meade 3.3 fr and a prostar .5 reducer. Here is a pic of ngc253 with a stack of 10sec x 6 on sharpcap. Astronomy .net gets the image as 1.29arcsecs /pixel which makes it f/3. In my hands the lx 90 on alt /az needs to be short and fast. I am not fussed about coma and vignetting as long as I can get an image. Paul
