Here's a gold star for you⭐ now go to the top of the class😆 This shows the more extreme part of the flaw. I'm assuming poor polar alignment also plays a role. Top left of image Bottom right

Thanks Adrian, much appreciated. Thanks Ciarán, fast optics and aperture certainly help also I think dark skies are very important too. Patience in processing is key too, small incremental adjustments letting the data guide where you go next.

Hi all, what a great few nights over the Easter weekend. 3 clear nights in 4 days allowed me to complete what would sometimes take weeks or months. Each panel consists of about 4 hours in 150 second subs. Shot with an Asi2600mc through a Tak Epsilon 160ed, mounted on an AzEq6. Captured with sequence generator pro Processed in APP, PI and PS. Hope you like it, Richard. Ps, there's actually a flaw in the mosaic. Top of the class to anyone who spots it.😀

Very nice, I've a soft spot for the Iris. Lovely blue colour at the core.

Thanks Ciarán. Unfortunately I couldn't enter some of the images I wanted too as they were already entered in another competition.

Superb image Alan.

looks like the Double Cluster is the winner. Thanks all👍

Many opinions and of course every one of them valid and all have given me pause for thought. I suppose the reason for the poll was because I couldn't make up my mind, so I think the best thing to do is to rely on it, then choose the one that comes out on top. I'll let it run for 24 hours and pick whichever has the most votes. Many thanks for all the feedback and opinions. This is a great community and while the subjects we post about may seem trivial in these times, it gives me at least, a much needed release. CS to all, Richard.

More opinions, more confusion.😁

Thanks for the feedback Dave, Double cluster seems to be the frontrunner here. Ref the Coathanger would it have helped if I called it Collinder 399😁

Thanks Simon, that was actually a first light image with my Takahashi Epsilon 160ed. Camera was Asi2600mc. 2 hours 60 second subs.

I think that's a good call regarding something transient, very much in keeping with recent interest regarding Neowise. I'm sure that's not true regarding the deep sky department. Plenty of wonderful images posted by you over the past year. That was the one I was considering until Padraig commented. His point about something more pleasing to the public's eye has got in my head. Do you mean the Flaming star mosaic? I entered that one and a mono version of the Andromeda Galaxy.

More food for thought, much appreciated Lee.

Hi Padraic, thanks for the feedback. I've already entered two images so it's just the final entry to be decided on from the above selection. I think this is a valid point, while Orion may not seem like the obvious choice to me, it may well be as you say the "wow" image. You've given me much to consider. Thanks.

Thanks Brandon, don't forget to vote.

Great potential there Gorann, I think it will be worth another visit.

Superb image Emil. Wish I had data this good just sitting on my hard drive waiting to be processed.😁

An outstanding image elevated to another level. Wonderful image, congratulations Ciarán.

As the Title states I'm entering a few images to this competition https://www.dias.ie/2020/12/16/reach-for-the-stars-diass-astrophotography-competition/ and I can't decide on the final image to enter. I've narrowed it down to the images below and would love to get opinions. Thanks in advance for any feedback, and don't forget to vote. CS to all, Richard.

Both images with a Tak Epsilon 130. 180 second exposures for Imx571 150 second exposures for the imx071. I see in your signature you use an Esprit 100. I imaged this with the 071 and Esprit 100. 9 panel mosaic.

I had both, the original had terrible frosting so I got the pro version as an upgrade. This also had frosting but not to the same extent. It was useable down to about -5. I have heard the qhy version is better but not completely immune to issues of its own.

Imx571 Imx071

No. Top image is a crop to show the reflections the 071 produces. No issues with refractors.

Hi Adam, I rate the 071 very highly indeed, in fact the main reason I sold mine (Asi Version) was because of the frosting issue. Be aware that it does give small halos with a reflector. See image below. I've also shot the same target with both the Imx571 and Imx071 and honestly there's very little between them, certainly not enough to justify the cost difference.

Very nice Rosette Adam, love the first one.
