  1. Thanks for the comments! :) Yes maybe it is a bit fuzzy at that scale, but I find it easier to see the detail when it's resized.
  2. Mars imaged last night with the C8 and Altair GPcam V2 mono and RGB filters and ADC. Imaged at 4000mm and enlarged 150%. After an unpromising start seeing became better than last time. 2000/8000 frames stacked and processed as RRGB. Time was 22.30 UT.
  3. Mars, imaged last night with the C8 and Altair GPcam V2 using RGB filters. Shot at 4000mm and enlarged 200%. 2000/10000 frames stacked.
  4. Good images! Yes I agree about the polar cap, much less visible on my image from last night too.
  5. Mars last night with the C8 and Alair GPcam V2 mono and RGB filters. This best result comes from using the long pass red filter as luminance for RRGB. Imaged at f.20 and enlarged 200%. 2,500/10,000 frames stacked for each of RGB. ADC used. Mare Cimmerarium dominates the disc right now. Imaged 00:45 UT.
  6. Thank you very much! I must say I'm surprised how well it turned out. This OSC image came out much better than the RGB. I've a suspicion there may have been some condensation on the fiiters, as despite the good seeing there was a heck of a lot of moisture as the humidity settled out.
  7. Well I had a session with Mars this morning. Set the alarm for 2 AM. It was worth it though, I did some RGB but here is a quick process of the image I took with the Altair GPcam colour. Scope was the C8 at f.20 and I used an ADC. 2500/10000 frames stacked. Enlarged 200%.
  8. I was looking for the comet but it was too low behind some clouds, but some great NLCs.
  9. No filters for this one.
  10. Thanks Ian. Though I don't have a tremendous experience with refractors I would rate the Altair as excellent value for money, a really first class scope for wide field. I have even less experience with quadband filters as I've never used any other but the Altair seems to do the job. Although I don't suppose they will ever produce the fine contrast of true RGB imaging they do save time! I'm very happy with the results I've got from mine. As to processing, I use Astro Pixel Processor and Photoshop. It takes a bit of experimentation to bring out the colours of the different bands.
  11. Thanks everyone. I think my personal favourite is the Ptolemaeus image in the second set. You can actually pick out every individual crater in the crater chain to the left (catena davy), something that you can't really do in the similar image from the first set.
  12. Thanks everyone! Nick, the seeing was indeed excellent, it's just that last time it was even better, probably the best I've ever experienced. It did occur to me that this may be partly due to the lockdown and the reduced pollution from aircraft, though I have no proof of that of course. I live in Caithness in the far north of Scotland and whilst we don't get as many clear nights as some parts when it's clear it IS clear, Bortle 2-3 at least. Funnily enough I can't find my previous post either, so here are the ones I did on 2nd May.
