Yep, I've been at it again The 27th of January gave us a fairly reasonable night after the misty rubbish in the sky cleared. It was fairly clear for a change So I quickly snapped a few of the ordinary objects but put a bit more care into capturing this time. Same gear (Canon 6D, 150mm f/5 Reflector, Backyard EOS, 90 seconds x 4 frames for all images. Stacked in Sequator and slightly fiddled with in Photoshop to remove more noise and fix contrast etc. M83NGC 2070 Tarantula and surroundsand SOMBRERO GALAXY (but I'm not real happy with this one)

You have re invented yourself with that Canon 6d Ken.Do you prefer the DSLR to the cmos cameras? Great images with 6 mins exposure. I presume you have your final image in Sequator a few minutes after that. Just wondering how good Sequator is on its own.How much difference does photoshop make?
cheers Paul Last night would have been ideal for imaging in Bendigo. Of course I was at a meeting. For summertime, the nights have been unusually cloudy around here. Just the odd clear night here and there and I am usually busy

G'day Paul, I do like using the DSLR but I still use cmos. In fact I was attempting to image Mars last night and showing Mike, another club member, (and a member in here too) how to do planetary imaging with the little 224 cmos camera. So I still use both types of cameras. I also use CMOS as a guiding camera at all times. Sequator is lightning fast. Some nights I take a few frames then put then into Sequator immediately. Other nights like the pics above were taken on the 27th but I didn't put them through Sequator until the 31st. The final stack in Sequator is OK, but Photoshop helps a lot if you have very dark images that seem to have little data. Photoshop brings out the detail. It's not fake or cheating because the detail and data is in your image, it's often just buried in the dark levels. Photoshop allows you to bring out the data you already have.

I like your M83 in particular. Do you need guiding when using the DSLR?

I like your M83 in particular. Do you need guiding when using the DSLR? Thanks Paul. Yes, I use guiding on my DSLR images. I use PHD2. But I don't guide when I'm just showing objects around the sky for visitors on our Public nights. On those nights I bump the ISO up to around 51,200 and do single frame snaps about 2 - 5 seconds long. Don't need guiding for that. At that ISO and exposure, objects can be seen quite well, but too noisy for keeping. It's a great way for the public (and the impatient people like me) to see objects nice and bright, in full colour, fast! Viva La near-Live Video Astronomy with a DSLR
