The Tulip Nebula SH2-101

[Parallax]

Well, despite the weather forcast I had to wait until 11pm for the last of the clouds to clear Cygnus. Normally I get bored after about 10 x 5 min subs but as everything was going so well I stuck at it. (The tracking error graph was almost a flat line). The result of more subs was a much smoother image (this jpeg doesn't do it justice).

There is, no doubt, more data to be teased out, but until my processing skills get better this is the best I can do.

30 x 5 min subs

Explorer 200, f/r (making it f3.8), Atik 16ic-s, Astronomik 12nm Ha filter

ST80, QHY5

Captured, guided & stacked with Maxim

Processed with PSCS

plenty of detail there steve.

why use the focal reducer? most newts dont take well to being focally reduced.

but you got plenty of detail there already.

keep at it. more subs always helps, did you find this to be true, with 3x more data than normal.

That's superb Steve, really nicely done .

Great contrast and very smooth. The extra subs sure do help dont they

Thanks guys.

Paul,

The reason for the f/r was down to framing - at prime focus it was a bit too large. The f/r is actually x0.5 but being a newt' focus is not possible with the f/r at the correct distance from the chip (I don't want to move the mirror). Therefore I have the f/r on a short nosepiece which equates to ~x0.75.

Lots more subs certainly does make a difference, so that's what I will be aiming for from now on.
