Cheers Harvey!

Super image again Geof!

Best image I ever got was on Jupiter Dec 2010 at minus 15 Celsius so that's the only aspect I'm not blaming 😉

Thanks Simon. I've forgotten certain things since I've been away from imaging and one is star collimation! Was watching YouTube about collimating the laser (mine is a baader so can't be collimated) and came across star collimation which I'd completely forgotten about.

Cheers Neil!

Poor seeing or not you've got some nice definition there Craig.

Taken a bit more time processing this image from Dec 8th. Got a bit more detail with a 10% stack. Had to use stronger wavelets (linked) than I normally would (making detail a bit coarse) presumably because this was taken through thin cloud and/or focus and collimation were slightly out as seeing looked fairly stable. 1.5ms & 465fps @ f18 for 5mins :

Very good detail Kostas!

Cheers Simon! Cold, tired and frustrated last night.....just like the good old days 😉 Using batteries 5 years past their use by date is not recommended for collimating a newt! Especially when you've only got one left and the laser needs 3! Having said that I might be able to salvage something better out of this solo capture.....

Thanks Kostas & Geof. If I'd spent £2 on new laser collimator batteries I might have got a better image (don't ask) given myself a dressing down.

That's a terrific capture Geof! I thought seeing looked pretty good and you've taken full advantage despite the clouds!

Clear sky all day and then it clouded over last night! One fleeting capture through thin cloud. Rushed focus. Seeing looked decent but this looks pretty soft. Taken at 22.41ut

Nice image Simon good to see you back 🙂

Brilliant work Kostas!

Great capture Geof! You must have been chuffed with that! Catch of the day! 👏

Yes in theory the ADC should correct that but it's not 100% reliable.

Yes i use registax to rgb align. Yes your image looks the same. Are you taking the rgb align box to the outer edge of the image frame? At least you now know how to increase your crop sizes 😊

Ok figured out whats caused it in my case and it is the tight box size but its the rgb align thats causing the issue. Just increasing the box size in as3 before stacking is all it needs.

I would imagine you could increase the ROI in pipp to see if it makes any difference on these captures?

I'm guessing it's caused during stacking because the limb is too tight to the capture frame but on the uncropped ser file there was no yellow hue or on one's I'd cropped with a larger box. At first I thought I'd forgotten to RGB align but it wouldn't budge the coloured limb.

Just wondered Geof, how tightly do you crop your captures before stacking? I notice there is a yellow hue on your limb. I had a similar effect on a Mars video capture I'd cropped too tightly in pipp. It may be coincidence but thought I'd mention it.

I enjoyed it, you've got some good data there. Yes looks promising this week. Proper clear nights and high pressure system.

Looking good! Glad to help out a fellow Dobber 😉

Best of both worlds 🙂 You could stay in AZ mode and use derotation of video to correct the field rotation on a 6 min capture though derotation of video is a much longer process (depending on your computer spec). Derotation of images is much quicker but doesn't correct field rotation if the original capture is too long. Whichever combination suits you best at the end of the day.

If youve got another 4 min capture with similar detail or even 2 or 3 within say 20-30 mins then yes, combining the stacked images in winjupos to derotate the images would make a big difference to what you can do with processing without worrying about introducing noise. Are you using an EQ mount because you could do 6 min captures? There are several tutorials on the winjupos website.
