AstroGS Posted June 18, 2022 Share Posted June 18, 2022 (edited) North American Nebula (NGC 7000) last night. RedCat51 EQ6R-Pro (tracking has been absolutely fantastic and steady on 0.30-0.35, during the whole session) Asi533MC Pro L-Extreme ZWO AsiAir Pro, ASI290mm mini integrated and processed on Pixinsight (NoiseXTerminator is surprisingly amazing). 20 x 600secs Darks, Flats & Bias Edited June 18, 2022 by George Sinanis 21 Link to comment Share on other sites More sharing options...
symmetal Posted June 18, 2022 Share Posted June 18, 2022 Excellent for the relatively short integration. Your Redcat is certainly shining now. 😊 Alan 1 Link to comment Share on other sites More sharing options...

Roy Foreman Posted June 18, 2022 Share Posted June 18, 2022 Really like the colour rendition. 1 Link to comment Share on other sites More sharing options...
Lee_P Posted June 18, 2022 Share Posted June 18, 2022 Really good, especially given the short integration time 👍 1 Link to comment Share on other sites More sharing options...
tomato Posted June 21, 2022 Share Posted June 21, 2022 Great result from less than ideal imaging conditions. 1 Link to comment Share on other sites More sharing options...
gorann Posted June 22, 2022 Share Posted June 22, 2022 Great result indeed! My only issue is the slightly confusing orientation. North is now to the right rather than up so I would rotate it 90°. 1 Link to comment Share on other sites More sharing options...
AstroMuni Posted June 22, 2022 Share Posted June 22, 2022 (edited) Great image @George Sinanis and considering the level of darkness here and the size of your aperature, its amazing ! Do the darks help - as I thought ASI533 had no amp glow? Edited June 22, 2022 by AstroMuni 1 Link to comment Share on other sites More sharing options...
scotty38 Posted June 22, 2022 Share Posted June 22, 2022 That's a wonderful mage no doubt about it but can I ask about the guiding and how you are managing to achieve 0.3/0.35 out of the mount please? I have an AZ-EQ6, so broadly similar, and I will see 0.4 in very short bursts at best but over a night of imaging the best average I will see is 0.7 which I am very happy with but if it can be better then I'm all ears 🙂 1 Link to comment Share on other sites More sharing options...

But, you are right....... it seems that it needs to be rotated 90 degrees anti-clock wise. Link to comment Share on other sites More sharing options...

I would always use darks regardless.... i think that darks help with the depth of the photo overall. 2 Link to comment Share on other sites More sharing options...

Also sky conditions play a huge role for that. I will take a couple of pictures next time i get it up and running. On the other hand, do not forget that the RedCat51 (with all the kit on), does not weigh more than 3.5kg-4kg. The SW EQ6R-Pro does not even sweat to handle it.

scotty38 Posted June 22, 2022 Share Posted June 22, 2022 Thanks and with you on all that and I would say that I have my balance and PA down too. Guiding is usually good (ie no issues to speak of) and my kit is not that heavy, all up it's about 8Kg (GT81) although I'm in the middle of a swap so will be a little heavier once I'm back up and running again. As far as the sky is concerned I'm in a good 4 so generally no massive issues there either unless the moon is up so yep you've got a good 'un!

Interestingly enough, when i use my GT81 rig - it is a bit heavier (approx 6kg with everything on) the guiding averages around 0.5-0.7. But again, it is not representative because sky conditions were not the best...... Edited June 22, 2022 by George Sinanis Link to comment Share on other sites More sharing options...
scotty38 Posted June 22, 2022 Share Posted June 22, 2022 Either way you seem to be getting very good guiding figures. Looking at the cables are you not pulse guiding either???? Link to comment Share on other sites More sharing options...

Yes correct - it is through EQDIR from the mount to Asiair and then the guide camera (through the main camera) connected to the asiair. This little thing (asiair) can make even newbies like me, take decent photos 😉 2 Link to comment Share on other sites More sharing options...
Astro_mark_c Posted June 24, 2022 Share Posted June 24, 2022 Looks great, I have the Redcat with the ZWO 183 mc pro. Great little pairing. 1 Link to comment Share on other sites More sharing options...
