Very nice set,

You captured a lot of action along the limb in both shots.

I love the lift off prominence's in the first shot (always my favourite), and all the spicules along the edge you caught in the second.

(I hope your images help to ease your trauma of moving! )

Thanks for sharing.

I love your images, especially the spicules. I have been trying to image mores spicules on my 102 like you have but haven't been able to. Your images were taken in SS. I've not tried imaging in SS with my 102 only DS. I am going to try some images in SS and see if I can get images like yours. Thank you for sharing your beautiful images.

Best....Hank

Thanks all, glad I could contribute a bit to the great work ya all do!

 

 

I hope your images help to ease your trauma of moving!

They certainly did, lol.  Was nice to feel some normalcy:)

 

 

2.5 x with asi 178 on 100 mm?  Nice!

Ya, a bit overkill, but I've found that given the sensor pattern noise this camera suffers from at small scales (also the 174 at times?), oversampling takes the size of the level of detail I'm trying to sharpen to a higher and larger level then the sensor pattern noise, so I'm not limited by that pattern noise when trying to bring out details.  Its always nice when the seeing allows for the 2.5x because I know post processing won't be as much of a struggle.

 

 

I have been trying to image mores spicules on my 102 like you have but haven't been able to.

I found 2 things really helped me do this, as I used to have trouble with it as well.  First was to capture in .ser format with the max bitrate the camera can do, 14bit in the case of the asi178.  Second was to save the stacked image in a 32bit fits file in autostakkert to maximize preservation of the faint details and then process the image in programs that can handle that bit depth (pixinsight in my case).  Having exposed for the disc only, I can then stretch the image to bring out the spicules and prominences more easily than I could capturing in 8bit video and using tiff files.

 

I don't know a ton about this stuff so some of what I'm doing might not actually be doing anything at all, but its been working so I've kept doing it this way, lol.

 

Thanks again, and I look forward to seeing more of all of your images!
