Well I had a fairly productive night under the stars despite the almost full moon! Started out learning some new techniques for my DSO imaging, drift alignment with Metaguide etc... and gathering data on M57 until the unscheduled clouds rolled in for a laughs!!! Went to bed and set the alarm for 03:00 this morning when Jupiter would be in position for an image run... Got straight into it with the ExtQ, then I decided to try to see if I could increase the amplification of the ExtQ by adding a short extension tube and guess what it worked... This morning I calculate that I had about 1.9x instead of the 1.6 times magnification and you can clearly see the diference in the image set attached below. All image runs were 2000 frame @ 30 frame / sec using Firecapture and the DMK21 USB camera. Also, I now have a Celestron Ultima 2x barlow on its way to me from the UK, so when I return from my business trip, weather gods permitting I can push the Mewlon harder. I hope yo like the set, everything has been processed in the normal manner. However, I'm going to have a play with A2!S this afternoon to see if I can make any improvement. Your tips / suggestions are welcome? PS it great imaging the planets, I can post the result the next day, with DSO I have to wait sometimes a month to complete the image!!!
A big thank you to everyone who commented on my Onion ringing problem because its now solved , great! I think the decisive fact was the Gamma needed to be at 100 or greater. At approximately 02:30 I managed to get this set of Jupiter images using the modified Mewlon M250S (CR Baffle added) and the DMK21 with the correct settings!!! They are only mono, taken using and IR-Pass filter; one day I will invest in a manual filter wheel and the necessary RGB filters but for now I'm very happy with the results. Still need some advise; As anyone used Metaguide? I'm trying to use this for collimation of the scope? I have read the manual and I think collimation is bang-on but want to push to get that last bit of perfection!!! Problem was that the "red dot" was moving around too much. Very close to the centre of the star and not too far away but perhaps I could have got a better result with a better technique??? Anyway, I hope that you like the images Most probably seeing conditions were the limiting factor
