Hi,
this is the first image taken by my new (for me) VC200l. Bought it from an Iceinspace member just before xmas. The collimation was way out, had to redo everything from first principles using special tools. I ham having a slight problem with sag in my connections which means it is not as good as it could be. CCDInspector reports collimation accurate to 2.5 arc secs. I will firm up my adapters before trying for sub arc sec alignment. This image is 30x60sec, no flats, darks or bias frames (QHY8) shots under a 3/4 moon through whispy clouds - I'll take any night that I can see some stars as a goer!! Used an IDAS LP filter. I am unsure how far to push the image for display on IIS, looks OK on my screen. Please let me know if it looks noisy to you....
A very nice image of this mesmerizingly beautiful open cluster. The VC200L is a great ‘scope albeit with rather thick secondary vanes. Was this at F9 or did you use the Reducer?
Nice indeed... Those VC200L's do produce lovely star images... Once you get the collimation down to sub arc-sec (not that I can notice any miscollimation in this image) you should be able to produce some killer image with this setup.
