Hi Guys

First bash with a new scope and new camera. Recently acquired a C9.25 to use as a "travel" scope as I am going for an imaging trip (ahem!! family holiday) abroad soon. This is a mosaic of three very overlapping images taken in average seeing. Camera was a ZWO ASI174MM. I used a 4x Powermate, so including the filter wheel and Crayford focuser on the scope, this would probably be about F45-50?  In future, I would think about F30 would be more suitable for average UK conditions.  You live and learn...

If anyone is interested, looking at the videos I have a couple of other images of similar resolution to this one.  Let me know if you would like me to post them.

Looks like the 174 is starting well. Is that its first light?

Thanks Steve.  Yes it was.  An absolute pleasure to use when it comes to collimation.  This image is a complete opposite, in terms of sun angle, of one I took a few years ago; here is the link:  http://www.pbase.com/nicksmith/image/121109725

Looks like F45-50 might be a bit high but you have achieved great resolution. I am always interested to test the limits of my C9.25 so would be pleased to see the other images taken with this scope. The 174 is looking like a good camera but could you tell me what filter you used? I recall looking in awe at your images from Oxford and the Canaries with a C11 some years ago if memory serves me correctly. Keep em coming

Great image Nick. You have certainly pushed the focal length, but that has came out well

Hi Alan

Thanks for the comment.  It was with an Astronomik red filter.  I will definitely be posting a few more images taken with the C9.25 in the next month or so.

Cheers
