Ha Image (eyepiece simulation) and a Quick Question

[JamieW]

Seeing as sunspots are few and far between today I thought I'd have a go at making an image of the Sun as it looks through an eyepiece.

Secondly, anyone know what might be causing this Interference? The image was taken using a 3x barlow, QHY5 and Lunt LS60. I think it might be the barlow as I had similar issues using 2x.

Cheers,

Jamie

Fabulous image!

It is Newtons rings and yes the barlow always make them worse. Sometimes they are improved if you can get everything a little straighter and more in line (the camera and the barlow). Sometimes it seems to be increased by the glass in front of the camera chip. Use a flat frame and in processing it will remove them.

As Alexandra said!

Many thanks. Now you mention it I think the barlow may not have been seated properly.

Very good impression. Reminds me very much of the view through the Lunt 60 at Olly Penrice's place.
