Wishing I had more focal length for this target. It's such a beauty but so small.

A very nice set of images has been presented. M57 is a small target and I see you've managed to capture the faint IC1296 which is no mean feat. I imaged this with the C14 so you can have a look at a few of the fainter details especially IC1296 which is a faint spiral. M57 is surrounded by a faint shell of gas which you've started to capture in your image.

 

My image can be viewed here https://www.astrobin.../full/o71spv/0/ zoom in fo a closer look. The conditions when this was taken were a bit hit & miss- I will go back and revisit in the winter.

 

Thank you for sharing.

Very nice.  I personally like images that show targets in context.

Thanks! I wish I had more focal length, even something like the 9.25" Edge HD would give me a bit more reach.  You image is lovely with so much more detail than I'm able to pull down with only 652mm fl.

Very nice! You got most of the colors out of that tiny object. good focus too.

 

Mine is all green and a hair out of focus.

You've done really well to capture the details you have. Part of the problem is when you have a small image scale the entire image gets put onto a very few pixels on the sensor- this is bound to loose detail as a larger image scale gets spread over more pixels to give you a finer grain image.

 

I also face the same difficulty with my RASA 11 at only 620 mm focal length. I've just ordered a small sensor ASI183 pro to experiment with what very small pixels of 2.4 um will give me on the RASA 11. I'm pretty sure detail is lost with bigger pixels eventhough I've not tested on anything smaller than 3.7 um.
