Due to the lovely weather recently, I gave m51 a go. This is a stack of 80x4min frames processed in photoshop, pixinsight and topaz labs denoise ai.
My solution to the problem of my telescope falling off my Equatorial Platform. I have replaced the central bolt of the Orion UK Dobsonian telescope with longer one and bolted the base of the rocker box to the top of the platform. I have replaced the nut with a wing nut so that I can easily attach and detach the rocker box from its base.
Still not able to get PHD to work. So here is an unguided image of the Cone Nebula. This is 50 x 2 minute subs in Ha. The Scope is the Takahashi Epsilon ED180 @ f2.8 and the Atik 4021. This gives a Field Of View (FOV) of 102’x102′.
I’m getting the data for RGB so will post a HaRGB image later.
For those who don’t know, if you hover the mouse over the image and click, you get a magnified image.
