Pleiades.........Almost.

Hi guys,

Taken with my modded Canon 600D and 100ED @ native FL.

8 x 1200 secs @ ISO 400.

A quick ABE, HT and CT in PI.

I think precise GOTO was having a bad night .

Good start, lots of detail. You just need flats to get rid of the dark spots and maybe a longer focal length to get more of the target in.

Thanks Neil, looks like i'll get another go tonight so i will take some flats.

Shorter focal length to get it all in?

Nice, up and close, and with lots of detail in the nebula. I like it.

A masked stretch will probably help keep the larger stars under control.

A tip for better goto alignment: use a short fl eyepiece with a barlow. Preferably an eyepiece with crosshair. This will put any target right in the middle of the view finder.

Thanks guys.

I'll use the focal reducer next time and the reticule eyepiece is next on my list.

TBH honest Wim i had been imaging another target and just did a precise goto, waited till mount was still and started imaging again, i think i was getting tired by this time.

Thanks for the tip re masked stretch, i'm slowly getting the hang of a few basics in PI, iv'e also just now downloaded the e-book "inside pixinsight".

I would always look at the image when choosing the final framing. Who cares about the eyepiece view? It tells you nothing about the camera's field of view. The picture you see in the camera is the picture you are going to get. Look at that!

To clarify; I use the barlowed eyepiece to get a good accuracy in the goto alignment (=2 star alignment in Synscan) and in the polar alignment (also Synscan routine). I then remove the eyepiece and attach the camera. The barlowed eyepiece give me the accuracy that will later help get the target very accurately in the middle of the sensor. If I find during a test exposure that I want to reframe the target, I will. I agree with Olly that an eyepiece view of a target is irrelevant for imaging. You may want to reframe a target for better composition, and the field of view of an eyepiece is usually very different from the field of view of a sensor anyway.

Unless of course it's this kind of eyepiece view.

Cheers,
