First Photography light!

On saturday night i went down to chittering in hopes of helping my mate "Leinard" to take some awsome guided shots being a nice dark site and all, though after many hours trying to get eqmod operating smoothly both of us had given up on the show.

Some friendly help from a man name gary i belive it was had seen that my scope was very close to being polar aligned, and then at about 2am another friendly chap called Shane viewed my pictures taken of Centurus A, he asked what i had taken it on and to his surprize the scope without the guide scope was the culprit.!

A bit of checking and fiddling and the polar scope was cracked out and to our surpize octanis was very close to the astrism seen!!! so i though why not align the polar scope to the astrisim and see how we go.

Well... I thought maximum unguided exposures where 2 minutes anything above that and your lucky. 5 minute subs on the Pinwheel galaxy no problems Sombreo, Centuras A and Eta Carina area.

What more can you ask for? Unguided Eq6 running no PEC just Polar aligned balanced with 1 SW weight and a Paver held on by G clamps... There is a bit of Coma noticeable but running at f#4.7 this is to be expected, also daniel helped me a fair bit with operation of the dslr (as it is his) but its all in the name of knowledge sharing .

Pinwheel 5x5min subs bin 1x1 Cannon Eos 350d, Stacked in DSS, Darks and Flats subtracted
Eta Carina 5x 2min subs bin 1x1 Cannon Eos 350d, Stacked in DSS, Darks and flats subtracted
Centuras A 5x 3 min subs bin 2x2 Cannon Eos 350d, Stacked in DSS, Darks subtracted
Sombreo 5x5min subs bin 2x2 Cannon Eos 350d, stacked in dSS, Darks subtracted
