Guys, how do you process your stars? Mine seem to come out fuzzy??... Tried star masks but somehow it's not quite right and sharp.
-
I use AstroTortilla too, but slight differences b/o movement or camera rotation already make a difference. In particular if you're stacking like 100 images...
-
After a long abscence I've finally managed to start with NB imaging... Moon was up - but with Ha you get quite a good result as opposed to my previous Canon attempts... lol Anyway, judge kindly, I somehow need to figure out how to prevent stars from bloating. As well - On the stars right hand side I can see an indentation which I think stems from the focuser tube jutting forward into the scope tube. Anyway - now I'm waiting for clear skies to add OIII and SII. Oh, and I've realised that by imaging several nights and adding more images you de facto are making your final image smaller, because you will never be 100% spot on with your subsequent images, hence cutting off at the edges in stacking. So I guess - looooong exposures is the way forward to increase image size... sigh... On the bright side (even though this image below is 500s exposures) I did manage to do one night of 1000s for the first time with SII. With the moon nearly full, you couldn't really see anything unfortunately. And, now all these images are stuck on a USB stick that suddenly decided to pack it in... uff

I know that Uranium has actually sawn of the ridge of the skywatcher coma corrector in order to put the whole camera setup further inside the focuser and thus reduce the length the focuser sticks into the actual tube. Would there be another coma corrector fitting the 130 pds where you wouldn't need to do that? Anyone has one?

My tutorial for installing, setting up and using AstroTortilla
Russe replied to Gib007's topic in Discussions - Software
Ooh, just recently had an issure with AT - I've tried using 2x2 binning and it really didn't work - so I went back to 1x1 binning and it found me again. What a drag sometimes... -
Just had my baby out after almost a year with the new camera - and suddenly it started raining. So I hurriedly ran everything inside. Now, 30min later it's clear skies... I'm going to sleep...

Using a Cheshire Collimator?
Russe replied to Thirdway's topic in Getting Started General Help and Advice
With this video I finally found out that I spent 25£ on a useless laser... it's completely out of line AND can't be colimated (lol)... I never understood, why I get things spot on with my cheshire, but my laser was always out a mile. If you buy a laser - test it as mentioned above by rotating it in your focuser and see if the laser spot remains in one place or describes a circle. If it does - it'll need colimating itself. I found my new laser very helpful for adjusting the primary mirror, but I double checked with the cheshire to be sure. -
Can't wait for Christmas now...
-
Oops - should've read your entire post
-
Lol - I got that NB part - what about your lights?
-
Which light pollution filter are you using?
-
Amazing! Which filter can you image with under full moon w/o problems? SII, OIII or Ha?
-
Am super excited - about to jump in at the deep end - hovering over the buy button for an ATIK 314L Plus... Anyone here imaged with the 130pds and this ATIK CCD???

Me too - I've only got a few Jupiter videos on my hard drive. Need to find time to see what I can do with them. Tried again with a Barlow - result: atrocious. Again. Seem to be unable to Barlow anything AND get a sharp video...
-
Yep - that's definitely my problem as well!
