Ok, almost up to the present, but not quite.
nice, M81 Bodes Galaxy
M5 Globular Cluster in Serpens Caput
Found that after the collimation saga, I could no longer used the DSLR at prime focus without a barlow. This didn't seem an issue since the GoTo is so accurate. Then , oh no, look at my shots of the DumbBell Nebula...
Glowing M92 Globular Cluster in Hercules
Glowing M27 Dumb Bell nebula in Cygnus
From what I have been told/read, its likely to be caused by the (cheap) Celestron barlow. plus I haven't bothered with flats, just bias and darks.
So, my first new purchase = Revelation 2" Barlow -oooooooooooooooooo lovely!!
Another issue was that to get accurate timings, I have been using the built in intervalometer in the D5300. However, this restricted me to 30 second exposures> From a few longer ones, I know that the mount is good for up to 180 seconds, even without guiding. So, I bought another Ebay special, a remote intervalometer. Works a treat. Just need dark skies now ( In June?!?!?!)
