Just a quick one to see how the data was. Will get more tonight hopefully.

Well done, the N70 bubble nebula really shows up well

Thanks Scott a 16 min exposure really shows up any EQ axis misalignment or guide scope misalignment from the imaging scope. Being able to leave everything setup means it is worthwhile really getting polar alignment spot on or very close. Also collecting data on many nights is now a breeze as the whole setup does not change. I would like to see a few objects in this field imaged with a 24" RCOS. Images below.

Managed to collect another thirteen sixteen minute frames of O3. Here is a large image of colour with the 100ED and the new NB data 1.5MB

That's a really nice picture Bert. Very sharp and colours are great.

I always have problems with the Tarentula.

Yes a lovely field of view that and I agree, would be good to see some of those bits up close and personal through a big scope...Peter W, Jase...???

Peter W and Jase are right you just cannot beat lots of collected photons.
