Zummerzet_Leveller Posted January 29, 2023 Share Posted January 29, 2023 Here's 10hrs 50mins of data on the Witch Head Nebula, taken over 3 nights after it pops above my neighbours house and then before it drops below 20 degrees. I was looking towards my local town so there was a fair gradient. Taken in 300s exposures with the 2600MC and the Baader Moon & Skyglow filter. I used the Redcat51 on my slightly tweaked AVX mount. I've flipped the image to give the classic Witches face. I think my backspacing with the Baader filter is off as stars seem to have some fringing that I've tried to control (or I need a better broadband LP Filter). All processed in Siril, Gimp, StarnetV2 and Topaz. C&C welcome. 16 Link to comment Share on other sites More sharing options...
James Posted January 29, 2023 Share Posted January 29, 2023 I like that  - I’ve been trying to capture this but am being defeated, so far, by massive gradients from nearby light pollution etc. Then again you have about 8 hours more data than I do! 1 Link to comment Share on other sites More sharing options...

Thanks James. I too had some annoying gradients. Just integration time to get the data and the pretty good gradient tool in Siril. Isn't 10hrs with a OSC equivalent to 2hrs with a Mono... 😉 1 Link to comment Share on other sites More sharing options...
