Good start Sarek! Unusual colour palette, is that from a mono?

Wow, that’s a superb image of the Rosette.

What a great set of images Dave, great detail up close and widefield. Well worth the effort over the years.

After Sundays glorious session in the evening, we have another clear night and allegedly tomorrow too 😳 Total shock…my reaction was like Del and Rodders in the auction house. Finally some good weather and clear skies, with my new Samyang 135 riding atop with the 585mc. Id prefer to go down @Vroobel’s route of two rigs, but that requires more ££££ ! £6.5 million from an auction of a watch might help!

So essentially the method you described to me previously for multiple sessions. This is what I had been trying, but I had extracted the Ha so it was a single channel and so it didn’t work. But yes, I guess I could combine all 3 channels from RGB and dualband. Thanks Oni. That’s what I was afraid of, I did this for my 6 panel of the heart and soul, and I’d agree it was more trial and error than guesswork. I guess I was hoping there was a command that would do it automatically. Thanks Elp.

Thanks @Elp and @ONIKKINEN . So if I layer the two datasets in GIMP, they will have different rotations. Is there a way to align the two layers, so they have the same rotation, and stars are in the correct place? Other is it pure guesswork? That was why I tried to register both together in Siril, and why I couldn’t use pixel math.

I have previously collected RGB data with my OSC camera on a target, but I have also been collecting Ha/OIII with an lenhance filter. What’s the best way to combine these datasets? I have stacked the RGB, stacked the dualband data separately, and then stacked them together. It works, but is this the correct way of doing this? Since I use Siril, I did try using the “extract Ha and OIII” script, and I thought I might be able to take the calibrated files and register them with the RGB calibrated files, but since the RGB and Ha files have varying numbers of channels (obviously), Siril won’t allow this and it needs a matching number of channels. So the only way I can see of doing this is to “stack the stacks”.

Welcome to SGL. When I got my first mount, I thought I would be a bit more mobile or setting up at the bottom of the garden so FLO recommended this battery pack (when they used to stock it), with this power lead and adapter to the power pack. That was a year ago, it still works fine but I’ve never gone mobile or further than about 4m from the house. The power pack will last all night powering my mount (HEQ5) but I won’t power anything else from it - one night I attached a single dew strap and it was drained after 4, maybe 5 hours if I recall. So powering another strap (on the guidescope), camera and other accessories just won’t happen. I recently purchased an ASIAIR and FLO recommended the Nevada PSU that @900SL states above. They originally recommended it when I bought the battery pack, but as I thought I would be further away or mobile, it didn’t really suit my perceived needs. In reality, I should have bought it first time around, as it will power everything, like he says, and will be reliable given that it’s powered from a mains socket. I’ve kept mine inside, and run a 5m cable out to the Air. I haven’t tried it for the HEQ5 yet, only for the Air on a Star adventurer and 585mc camera. But it worked flawlessly, and hope to set up on the main mount soon once my current target set is completed.

Although technically not a delivery from the post, I picked this one up today from a local camera shop after trading in another lens. Nice to support a local business, and cannot wait to try this one out.

I have had no issues at all with deliveries through Royal Mail, and the smaller items I’ve ordered from FLO have always arrived on time, with the postie on her usual round before lunchtime. So I’m surprised to read this. I guess we must have good posties in Gloucestershire @PeterC65 👍 Larger items tend to come from DPD, and my village appears to be their first visit since they have often delivered to me before 9am. My SF102 arrived at 8.15 after ordering at lunch the day before. Top marks there for FLO and DPD.

Michael has described it perfectly, and this page on Astronomisers website (where I got my camera modded) gives a good explanation of the correct types of modifications and shows some examples of images taken with each. Hopefully that should assist.

Nice work! Feels like we are all in the same boat. Allegedly I have some clear skies tonight...starting after Moon rise, so it might be a cluster night again.

Wow, I’m surprised that worked a whole year on! Great thinking. Very impressive Lee, looks much better now the black lines have gone. Well done, and look forward to your images this year 👍

It certainly did, I can’t unsee it now! Thanks Martin - the monkey overlay did it 👍

I’ve never explored resampling, it might be worth considering and exploring from my end then. Assume this is done in post, whilst still in linear? I’m sure I’ve seen an option in Siril for this. Thats an insane image Lee, 21 panes?! I’d never have guessed that that image was less than 2 hours of Ha and 1 sub per panel! Very impressive! Funnily enough I do have a SY135 on the way, does that count as a “scope” 😂

Nice result and nice colours. I never see the Monkey on this one, ever.

Thanks @geeklee ! It’s just on the edge of Camelopardalis, north of the Heart and Soul. Yep, UK weather definitely has! That and the 6 panel Heart and Soul with varying light pollution, etc, that I did last year… The 15 panels for the Hyades, even at 15 minutes per panel with no time lost for dithering, slewing, etc, would work out as 3.75 hours. It might be doable, but background noise would be bad. Maybe I need a smaller scope 😂

That would be a good idea, and would help weed out some of them. On a slightly related topic, this type of thing can only make matters worse going forwards (generally, not just SGL); https://www.bbc.co.uk/news/technology-67703018 . The power of AI, in the wrong hands, I find to be frightening.

Ah, good point. I’m always dubious with the nosepiece/clamp, do you suffer any tilt or other issues using that type of connection? I used it for my 585 with a Barlow for some planetary, but I felt like the screwed fit is more robust. If you do try the 0.6, I’d be interested in seeing what you achieve 👍

I wondered this, because if it’s who I’m thinking, then I did message about one of the items - including the one Tomato was interested in if he didn’t go ahead. I didn’t see anything out of the ordinary in the posts themselves, other than a low post count from the seller, and luckily I only sent an enquiry message. Thank you to the SGL staff for dealing with this 👍

Thanks 🙂 Yes, it is Astro modded - I purchased directly from Astronomiser, he bought a second hand 800d from MPb, then modded it and had it to me in 1 week. Dark current and noise are a bit of a pain, I have a 585 and the loss of that noise is incredible. As a result I’ve been looking at a 533 or 2600 for much later this year. Would prefer the 2600, but at that cost a 533mono with filters comes into play too… On the reducer… Interesting, the 0.6 would bring the Starfield down to circa f4 at 430mm focal length! It says it’s designed for scopes of f7 and slower so in theory it would work… Does it attach to the starfield 102? The scope has an M63 connection and the Stellamira flattener has m48, so it appears that an adapter would be needed. This would certainly get my attention if it works…

Love my Starfield 102, used only for imaging I purchased mine last April with this adjustable reducer and it hasn’t let me down. Using this and imaging at f5.6 is better than the flattener and imaging at f7, which you would find to be really slow compared to the 130pds at f5. I had several issues achieving backfocus with my previous scope (Evostar 72ed) with a non-adjustable flattener - and spacers were the bane of my life for that. Hated them. The adjustable version for the 102ed made it a lot easier. I didn’t realise there was a 0.6 reducer though? That might interest me…

Thanks Elp, no longer than usual. I have my routine down to a tee now 👍 I also planned to do this for the Hyades, but at my focal length it would need 15 panels…in UK skies it’s just not going to happen 🙄 Thanks Gus! Thanks Stu! I didn’t realise either, and it helps lift the image in my view 🙂 Thanks! Glad I got your namesake into the image haha.

No need to bleat on about the poor weather we have had lately, and of course when it has cleared, it has been very brief and adversely affected by The Moon. In the 4 hour period predicted yesterday, I decided to hit up a star cluster so that at least I could produce an image. I decided for Kemble's Cascade as a 2x1 mosaic, collecting 30minutes per panel, and then repeating again for another 30 mins per panel. I intended to do this 3-4 times and luckily that worked in my favour, given that the 4 hours turned out to be 2 hours before clouds stopped play. So at least I've finally got an image for this year. Wind ruined some of the subs, so this is 01:47 spread across both panels. Starfield 102ED + Canon 800Da, calibrated with darks/flats/biases. Stacked in Siril, mosaic stitched in ASTAP. NGC 1502 is the cluster to the right-hand side.

Given that I’m OSC rather than mono, I’ll be skipping SII anyway! Saying that, I have been thinking about buying an SII/OIII dual so I’ll know not to use it here, so thanks for the tip 😃 I suspect my sub lengths weren’t long enough too, seeing as you were using 900s frames so that might be part of it. Anyway, once again, great image.
