TiffsAndAstro Posted July 28 Share Posted July 28 (edited) fml must admit i was hoping for a hint of it. need to stop looking at astrobin pics of the day ;( Waste of 5 hours so I'm blaming 50% moon for no squid, or anything else of note Edited July 28 by TiffsAndAstro 14 Link to comment Share on other sites More sharing options...
carastro Posted July 28 Share Posted July 28 (edited) Love the drawing, Yes the Squid is something that has eluded me too. I can get part of it, but nothing like those fabulous images done in Pristine dark locations with load and loads of hours. the Oiii is VERY faint and needs hours and hours of data.

carastro Posted July 28 Share Posted July 28 Yes, that was done in a really dark location 51 1/2 hours. 2 Link to comment Share on other sites More sharing options...
Vroobel Posted July 28 Share Posted July 28 You need at least a dual-narrowband Ha & OIII filter, maybe the dark sky as well. 1 Link to comment Share on other sites More sharing options...
Ibbo! Posted July 28 Share Posted July 28 I found it a very challenging target and spent a lot of time on it. O111 only with CCD cam - I might have a go with the cmos cam at some stage. over a couple maybe 3 years IIRC 34 1/2 hours (many others discarded subs as well) and with some Ha and a reprocess 11 Link to comment Share on other sites More sharing options...

Elp Posted July 28 Share Posted July 28 Maybe more of a damp squib It's always fun experimenting but can knock you back when nothing "appears". Haven't tried this target, by the sounds of it I'll leave it for another year. 3 Link to comment Share on other sites More sharing options...

tomato Posted July 28 Share Posted July 28 As this thread may become a repository for "barely there" squid images, I can make a contribution. 70 x 3 mins from November 2021 with a RASA8/QHY268c/NBZ filter from my Bortle 5/6 location. I was going to image it again last night but found that when aligned with the object my guide scope was looking at the inside of the dome... 4 Link to comment Share on other sites More sharing options...

Too many people ask for "what best equipment to achieve X," or whatever, in this hobby I find you learn more from hands on and working through and overcoming any issues. I sometimes image very low down targets not expecting much of anything due to LP, but I've surprised myself sometimes even though signal can be very very weak against the LP. 3 Link to comment Share on other sites More sharing options...

So I you're saying I should go for omega nebula tonight then? Ok I will I put a pic of what I can see if the milky way in another thread. I think I can see lower down than I thought I could. But just because I can, doesn't mean I should Link to comment Share on other sites More sharing options...
Clarkey Posted July 28 Share Posted July 28 (edited) I have had to stretch the pants of the O3 on this one. 8.5 hours of O3 from B2 sky with a 12" F3.8 newt. Still needs more signal on the O3...... Edited July 28 by Clarkey Duff image 12 Link to comment Share on other sites More sharing options...

I really need a few more hours of O3. I will reprocess it to see if I can get a better result, but needs more time. 1 Link to comment Share on other sites More sharing options...

I think if they look 3 dimensional, it makes the composition. yours look really 3 dimensional. who knew i could see omega nebula in a 3 sec sub btw?

Nice, especially 70x3 minutes isn’t a lot compared to some images you see with hours upon hours. Might give this one a shot. 1 Link to comment Share on other sites More sharing options...

Very nice! On 28/07/2024 at 20:23, Clarkey said: B2 ... 12" F3.8 For anyone wondering about the ingredients - Clarkey's processing skill aside, these are certainly two - skies and speed. A great combo. On 28/07/2024 at 19:52, tomato said: I can make a contribution. 70 x 3 mins from November 2021 with a RASA8/QHY268c/NBZ That looks great too Steve. Just 70x3 but it's coming through clearly against the Ha. A great RASA object 1 Link to comment Share on other sites More sharing options...
tomato Posted July 30 Share Posted July 30 I’m currently relocating my RASA guide scope so that hopefully I can get more data on this object during the current clear spell. 1 Link to comment Share on other sites More sharing options...

carastro Posted July 30 Share Posted July 30 (edited) Well as everyone else is posting their failures, here are mine: This is mine from Bortle 4 after 6 1/2 hours: I then stretched it and stretched it until I produced this ugly result: This was back in 2017 BTW I then tried it with my Samyang 135 mm lens in Bortle 4. 9 hours 10 minutes of which I took the following in Oiii: Oiii 2 x 20mins, 2 x 30mins, and 7 x 15mins 3 x 900secs binned x 2 (total 4 hours 10 mins) Plus a further 3 hours on another night. Total Oiii 7hours 10mins and still this is all I got and that was after heavy strecthing of Oiii: I have now given up on the Squid Edited July 30 by carastro 4 Link to comment Share on other sites More sharing options...

geeklee Posted July 30 Share Posted July 30 (edited) 125 minutes of OIII, Samyang 135 + 183MM camera @ ~F2.8. Mix of B4 and B6 skies. A single 300s sub: @Adreneline I always thought we got more for this mosaic pane back in 2021? This was all I could find in my archive! Perhaps it needs revisiting Edited July 30 by geeklee 6 Link to comment Share on other sites More sharing options...

Perhaps it needs revisiting Um? I seem to recall getting 60x300s of OIII one (amazing) night to add to the stuff we already had. I need to look back to remind myself - a few grey cells have gone amiss since November 2021 🥴 We did this combined project before Xsuite processes came along, not to mention other amazing and helpful PI processes and scripts - definitely worth a revisit of the data I would say. 1 Link to comment Share on other sites More sharing options...
