ZWO OSC camera replacement for Canon 1100D?
Lee_P replied to callisto's topic in Discussions - Cameras
I use a 2600MC-PRO and it's fantastic. Its strong reputation is well-deserved. Just a shame it's expensive! -
I think that these are great, and also cover quite a variety of targets -- wide-angle Milky Way with landscape, Moon, planets, all from a first collection. Bravo!

Great that you can see the dust lanes with just 45 minutes of integration time!

Nice shot, I do like wide fields of view that capture the whole nebula.

New website! Urban Astrophotography: OSC imaging from a city
Lee_P replied to Lee_P's topic in Getting Started With Imaging
Thanks Andy, I've got a few ideas for new articles too -- just need the time to write them up! -
Great picture, especially as it's a work in progress. Impressive for six months too!

New website! Urban Astrophotography: OSC imaging from a city
Lee_P replied to Lee_P's topic in Getting Started With Imaging
Thanks all, good to know I've got at least three views..! -
Hi SGL-ers, I've been wanting to learn how to make a website using WordPress for a while, but needed a good idea for what it should be about. I settled on my astrophotography, figuring that making the website would be more fun if it's about something I'm interested in! In particular, I opted for the niche of OSC imaging from a city, because that's what I do, and the content may actually be of some interest to other folks out there. http://urbanastrophotography.com/ It took a while to build because I was learning from scratch, but it was a good use of Summer's lighter evenings! I hope that some people will find it useful. My aim is to update it with some new content every month or so. -Lee

Hi and welcome! I'm from Weston too, living in Bristol now. Great photos you've taken

Hi @Luke Newbould, I'm reprocessing another image using your method. I've made a slight change, and am wondering whether this it's something you didn't do on purpose -- if not, it might be a neat optimisation. Basically, I'm at the stage where you've split the channels into R G B. You've deleted B, and are using Curves and HistogramTransformation to make G look like R. What I'm currently trying instead to achieve this is to open up LinearFit, use R as the reference, and then apply to G. I *think* that achieves what you're aiming for with the Curves / HistorgramTransformation steps, but is simpler. Or maybe I'm missing something! Whaddya reckon? Thanks, -Lee

I had a QHY5 many years ago. I've fished out the driver I used (ASCOM-compliant). Fingers crossed it's helpful to you! QHY5ASCOM-V40.zip https://www.qhyccd.com/download/ <- "For Discontinued devices which are not listed above, please contact us." You could always email QHYCCD and ask, if the driver I found is no good. -Lee

Very nice!

Thanks! I get that mono is objectively better, but when I hear people say that you have to go mono if you're in a city, I kinda want to show them what can be achieved with OSC and an L-eXtreme... Haha no worries, I've been trying to get nice blues into my images for a while, and your tutorial completely cracked that one for me 😁

Sorry to hear about the thefts! I used to image with an 80ED too, and am now using an Askar FRA400 (https://www.firstlightoptics.com/askar-telescopes/askar-fra400-f5-6-72mm-quintuplet-apo-astrograph.html) It's a good upgrade to the 80ED, and reasonably priced for the quality. I wrote a review for it in the members' equipment reviews section. Looks like there's a long lead-time for it on FLO though.

I'm having a good time pushing what I can achieve with an OSC camera (plus L-eXtreme) from my city centre location. I think this is my best attempt so far. I push the data hard, which isn't to everybody's taste, but I quite like the "punchy" effect. * May and June 2021 * Bristol, UK (Bortle 8 ) * Telescope: Askar FRA400 f/5.6 Quintuplet APO Astrograph * Camera: ZWO ASI 2600MC-PRO * Filter: Optolong L-eXtreme * Mount: Orion Sirius EQ-G * Guide: William Optics 32mm; ZWO ASI 120MM Mini * Control: ASIAIR PRO * Software: PixInsight, Photoshop, Lightroom, Topaz DeNoise AI * 480 x 120 seconds ------------------------------------------------------------ Total integration time: 16 hours ------------------------------------------------------------ By Lee Pullen Huge thanks to @Luke Newbould for making an excellent PixInsight tutorial, which I used as the basis for my processing. https://www.youtube.com/watch?v=QV6ObLVRvNk

Thanks again for making the tutorial. It's pitched at a perfect level for me (and we have the same camera and filter!) I used your tips to help edit this Elephant Trunk photo. Amazing what we can do nowadays with OSC cameras even in light-polluted skies (I'm in Bortle 8). I'm definitely interested in any more videos you make!

IDAS LPS-P3 Light Pollution Suppression Filter
Lee_P replied to Lee_P's topic in Member Equipment Reviews
Thanks @vlaiv, you're a legend! From visual inspections I thought that the D3 was having minimal impact one way or another, but it's so much better having numbers to compare. -
IDAS LPS-P3 Light Pollution Suppression Filter
Lee_P replied to Lee_P's topic in Member Equipment Reviews
Thanks vlaiv! Here are some dark files. To answer your questions: yes they were taken almost successively and with the same conditions; and RGB combined sounds just fine, especially if it's quicker for you. Dark.rar -
IDAS LPS-P3 Light Pollution Suppression Filter
Lee_P replied to Lee_P's topic in Member Equipment Reviews
@Magnum Ok, two subs attached, both taken last night -- should negate any differences due to sky conditions. One IDAS D3-LPS, the other No Filter. Do you think there's an appreciable difference? @vlaiv, it would be great to get your opinion on these too, if you have time 😁 M81_NoFilter_120s.fit M81_D3_120s.fit -
I can't speak specifically about Canon cameras, or using them for astro -- but I've used Nikon DLSRs for years for professional photography work. and now am using a Nikon mirrorless. Mirrorless is definitely the future! I wouldn't consider a DLSR now. Mirrorless all the way 😁

Thought I'd join in the fun. About 15 minutes of editing time, mostly using PixInsight, then a little bit of Lightroom. I pushed it too far so it's noisy, but I reckon you've got some good data in there. I could do more but need to collect my daughter from nursery 😁
