Widefield M101 on a Star Tracker

[FenlandPaul]

To be honest, I'm fairly nervous posting in this section because the quality of images is fantastic! I don't really have a proper deep sky rig, and my usual interest is in widefield and nightscapes.  But as I have a tracker and a small frac, last night I thought I'd have a go at M101.  I was fairly pleased with how the galaxy came out, and the fact that many of the surrounding galaxies are also visible.  But I'm not so keen on the bloated stars, which is something I've often struggled with.  Anyway, here are the details:

• 345x 30s subs (172.5 minutes total)
• 61x darks and 62x flats
• Astro-modded Canon 450D
• Altair Astro Starwave 70ED (420mm f/l)
• Skywatcher StarAdventurer
• Stacked in DSS and cropped and processed in Photoshop.

Would always welcome hints and tips on how I can get more out of a simple setup like this.  Thanks! 😊
