Peter_D Posted March 5, 2022 Share Posted March 5, 2022 Hi, I've been trying to capture Sirius B for the last few sessions using my Celestron 6SE and Zwo asi224mc with a 2x Barlow. This evening, I recorded a video and tried to stack the images as per planetary imaging. There was no sign of Sirius B in my stacked image. However, I did see in AutoStekkert!3 that several individual frames were of good quality.. I scrolled through the individual frames and I have attached the ones that show a distinct separation - they all show this separate entity at just before the 12 o'clock position. Is this Sirius B?

chiltonstar Posted March 6, 2022 Share Posted March 6, 2022 Looks like it. B trails behind A, ie due E. What is the orientation of your images? Chris 2 Link to comment Share on other sites More sharing options...

Those images do look like they show Sirius B, but the question posed by chiltonstar could confirm. 1 Link to comment Share on other sites More sharing options...
Mr Spock Posted March 6, 2022 Share Posted March 6, 2022 Yes, orientation is important for the identification. In my Dob the pup follows. 1 Link to comment Share on other sites More sharing options...
Peter_D Posted March 6, 2022 Author Share Posted March 6, 2022 Hi, yes, I messed up in that I didn't orientate the camera so North was top and the video has Tracking on the whole time so no way to find out now ..😖 I stacked these good images anyway. Thanks for the feedback. Hopefully I'll have another chance soon. Clear skies Peter Link to comment Share on other sites More sharing options...
Mike JW Posted March 6, 2022 Share Posted March 6, 2022 Current position of Sirius B is PA 65 degrees (not due East) and a sep of 11.27". Hope that helps. Mike 2 Link to comment Share on other sites More sharing options...

Mike Agreed Mike, slightly less than due E at the moment. This is what it looks like with my 180 Mak. Chris 5 Link to comment Share on other sites More sharing options...
skyhog Posted March 15, 2022 Share Posted March 15, 2022 (edited) I have tried to observe the pup for a number of years, all occasions seem to end the same way, namely that I think I've detected it but never with the absolute confidence I'd like. Sirius is very low from the north of the UK and most sessions have it like a disco ball in the eyepiece. Last month I did have much steadier seeing, and also very good transparency so I decided to stick a planetary cam on the scope, the zwo 385, and see if I could observe it on the laptop in the obsy. I first got rigel on the screen. Played around with the gain and exposure and it was sitting there on the screen just as I view it visually. Then over to sirius, a bit of a tinker with settings and the pup was there blinking away beside its overbearing partner. I sat and watched it a while contemplating just what I was observing, then it was cam out and in with an eyepiece. Though I was telling myself it was there, and on occasion chalking this up as a success, it still refused to let me see it in a way I'd feel satisfied. Next year Rodney... Next year....

skyhog Posted March 15, 2022 Share Posted March 15, 2022 Sorry, the scope used was a 12 lx200gps Link to comment Share on other sites More sharing options...
