IC405 (Flaming Star) - Evo50 as imaging scope

[vineyard]

Hello,

In the little run of clear (but moonlit) nights we had at the end of Feb, I played w the little Evo50 + SW flattener as a wide-field imaging scope.  Mounted in an Astrokraken rig, on an HEQ5Pro, w a Baader UHC as a filter.  I've posted what emerged from M81/M82 & IC1848 in other posts, so this is the last target on which I had all of 45 mins of lights (60s, calibrated; Pixinsight incl a little bit of star reduction).

A lot more data clearly needed - but still quite pleased w what the Evo50 could produce in these conditions?  I definitely want to try and spend more time on this part of the sky whenever the clouds go away.

The glow in the bottom left corner is the moon I suspect.  Not quite sure what the diagonal band towards the right hand side is - it wasn't there in the M81/M82 or IC1848 images, so I'm not sure if its an actual feature or an artefact or something else.

One thing I've noticed in all three images is it almost looks like a ripple effect is also there - the centre of the image is brighter, and then a circular dark area and then a circular brighter area.  Could it be internal reflections in the train b/c of the UHC filter?

Cheers,

Vin

Good work Vin.  The nebulosity is starting to show and I think there is a chunk of the tadpole nebula creeping to view at the bottom.  The UHC filter doesn't offer a huge amount of protection from moonlight so you have really been up against it.  I'm not sure about the cause of the  background irregularies.
