While playing with my modified Canon 200mm, It seems I managed to image this nova (see email from AAVSO, below)
at the same time as discoverers.. if not a bit earlier
This image (200% crop) was taken on Oct 26th, 9:05 UT.
The suspected Nova is in the centre..
Could someone check this please, it is cloudy here in Melbourne at the moment?
On the image i took on 19th (with 135mm lens) there is nothing there...
