Tarantula 2070 at F10

Guys..

This image was taken on my C11 F10 at 2800mm FL using the Baeder 2" UHC-S filter on the G11 unguided...at my House Brisbane.

I started out doing 5 x 2 minute exposures at ISO1600....thinking hahaha here come the star trails....Unguided....what no star trails....I couldn't believe my eyes...fl of 2800mm unguided...Previously I couldn't even get 90 seconds at FL 1900mm.....without getting serious star trails.

So I thought lets push it a little further...5 mins is a nice round figure...lol

So I did 10 x 5 minute exposure at ISO 800....OMG very little sign of star trails.....at this stage I felt like I was in heavan.....never have I been able to get anywhere near the exposure length at this focal length....60 seconds was pushing it previously.

I also added 1 x 7 minute exposure ISO 800.....wow

I am so excited with the length of the exposures unguided then I am with the image but here it is anyway...I give the image 4 out of 10 score.

I still have to play around with the PEC and Backlash settings as they have not been touched.

Software used DSLR Focus, IMagesPLus, PhotshopCS....no flats or darks...they still wont work for me.

Comments welcomed.
