Thanks all - a few options for me to experiment with.

Thank you - just the pointer I needed 🙂

Morning all. I have around 450 subs of the Milky Way, taken to produce a timelapse. What I'd like to know is, can I process one sub the way I want it, then somehow apply that same process to all the other subs, prior to creating the timelapse? I have access to Pixinsight, or an early (CS2) version of PS. Any advice welcome. TIA Steve

A quick follow up re Craig's excellent advice; I ran my data through AS!3 again last night, whilst I was asleep, and awoke this morning to a set of eight stacked images, ranging from 10 to 400 subs per image. Absolutely perfect way to do this, and just what I'd hoped for. Thanks again Craig 🙂 Steve Edit: surprisingly, the best stack of the eight, was the best 25 frames of 5000...

Craig, you're a star! Thank you. I'd often wondered why there were four boxes for one figure, but that had never occured to me. I am enlightened 🙂 Steve

I'm experimenting with some lunar data I gathered, 5000 images in a SER file. As you can imagine, it's quite a slow business, despite my PC being reasonably fast. What I'm finding rather frustrating, is that having done the analysis of all 5000 frames, and stacked the best say 10%, if I now want to stack 5% to see which is better, AS goes right back to the beginning, and I have to go through tha whole analysis stage all over again. Having done it once, and ordered the frames by quality, is there any way to simply just stack a different percentage or number of frames, without going right back to the start? TIA Steve

Thank you both - all sorted now 🙂

I have the latest version of Stellarium installed on three different machines, a NUC, a laptop, and a desktop. On the NUC, when I zoom in on a target, I get an image of it; on the other two, all I get is the red circle. I've poured over the settings but as far as I can see, they are all set up identically, yet they can't be. Can someone tell me what setting I need to alter to get the images to show please? TIA, Steve

Thanks Michael. I had read that info in PHD2, but in truth, didn't quite understand it. Your info re the setting and dither amount is interesting though, and is something for me to check, and have a play with. 🙂 Steve

Thanks 🙂

As per the title, which should I choose? What makes one preferable to the other? Imaging at 1.05 arc-sec/pixel, guiding with a 240mm F4 scope and QHY5-II. TIA, Steve

With the recent arrival of Starlink, and future similar projects, it's only going to get worse 😞

I'm looking for a new mount, as my current CGEM is not performing to the standard I want. I'm considering the "basic" Ioptron CEM70, without the autoguider, but I've had several responses saying it's overpriced. Are there any alternatives in about the same price bracket (ie under £3k) that I should consider? I generally use a 115mm refractor, which weighs in at 23lbs with all its extras. I also have an 11" SCT that I'm hoping to use once it's been serviced which is heavier, at around 32lbs in total. This will be on a concrete pier, so I'm looking at a head unit only. TIA, Steve

Just heard back from Altair, and whilst the CEM70 isn't mentione in the list of compatible mounts for the AA Pier Adapter, they tell me that the CEM70 is the same footprint as the CEM60, so should fit OK. I'll report back if it doesn't 😉

Morning all. I'm about to pull the trigger on an Ioptron CEM70, and want to establish how to fit it to my "Todmorden" style concrete pier. I currently have an Altair Astro Pier Adapter fitted, for my Celestron mount; AA say it fits various Ioptron mounts, but does not mention the CEM70. Various other sites say I'll need an Ioptron Pier Adapter, which I'm sure would be fine, but may not be nescessary? Is there any reason why I can't simply sink a couple of anchors into the top of the concrete, and bolt the mount direct to it? TIA Steve
