Description

Continuing to test out the capabilities of the Star Adventurer mount - far from a 'toy' this provides pretty good tracking, albeit with well documented periodic error. This image represents unguided 3m exposures with my Pentax zoom lens at 75mm at f5.6 and CMOS camera. Manual focussing is a challenge to achieve and maintain throughout the imaing session, and I suspect I have some misalignment in my DIY CK adapter.

Rev A - stacked and processed in Nebulosity v4; Rev B stacked in Nebulosity and processed in Startools; Rev C the best 60% subs stacked in ASTAP and processed in Startools, and Rev D processed in Startools with star tightening and final noise reduction in Nebulosity. I have pushed back the stars in this final version to show off the wonderful diffuse nebulae in this region of our summer skies.
