Reprocess

Glad it works, just remember to remove it before starting your imaging run. Not that anybody has ever done that ever

Something to keep me busy on those cloudy nights

Thanks Thank you. Looking at it now I'm thinking maybe I've over cooked it. That's late night processing for you. I'll give it another go soon

After an absolutely terrible start to the evening on christmas eve taking over 4 hours to set up, I've finally managed to produce an image with my dual rig. 40 X 300 second subs, Ha 3nm on the Esprit 100 and ZWO183m 20 X 300 second subs in both O111 and S11 5nm on the WO FLT98, 0.8X reducer and QHY183m

Wow. Just wow

I finally managed to try out my dual rig, first time since I bought my 2nd scope in October. Had alot of issues getting everything set up and balanced. I started setting up just before 6 o'clock and didn't take my first sub till 10 o'clock. Once everything was working as intended I managed a few hours on the rosette nebula. Looking forward to processing after today's festivities are over. Ha with my esprit 100 with matching flattener, zwo 183 mono. O111 and s11 with my William optics FLT98, 0.8 flattener and qhy 183 mono mounted on my neq6. I used a skywatcher guide scope mount to align my flt to the esprit, but I need something alot sturdier as most of my time setting up was trying to get it aligned.

I just use the one that's for a wo star 71.

It really all depends on balance, polar alignment and most importantly the wind. I used to use the same set up and have achieved 30 minute subs but the slightest blow would ruin my subs due to the lightweight mount and the 200p acting like a sail.

Personally I wouldn't bother with any filters imaging from bortle 4 skies.

Personally I don't think flats are needed for every filter. I've always only taken flats through my luminance filter and I've never had and problems with them not working. I don't have a permanent setup so I have to build up and take down every session, but I do always leave the imaging train alone. My cameras are always connected to my scopes and I move them independently of the mount. With regards to framing, couldn't you just rotate your OTA inside the tube rings? I know it's not ideal but may be a better option than constantly taking flats and trying to remember which flats go with which lights.

I've used both OSC and mono versions of the qhy183. A trade ad came about that wanted a straight swap for a zwo 183 mono. I now have 2 mono cameras. For me as I live in bortle 6 location then mono is better as I have the opportunity of pure narrowband imaging when the moon is about. Plus my filters are pretty good at reducing the effects of light pollution. Yes Trevor does seem passionate and gets to review alot of equipment, but would his reviews be the same if he had to buy all of the equipment he reviews? Personally I don't think they would. There is also a good chance that suppliers know this equipment is going out for review so they ensure the equipment is perfectly functional. I recently posted an image in the "imaging with Samyang 135" thread that was taken in less than an hour. The OSC camera could never have got the same results in the same time, from my location.

Here's a very quick M45 as a test image. 24 x 60 second Luminance, 11 x 30 second RGB taken from my back garden with bortle 6 skies at f2.8

The only reason a company exists is to make money. The more variety they make, the more they will sell. It's like cars, they will all get you from point A to point B so why does 1 company make so many different kinds, to make more money.

Mine arrived a couple days ago. It's gonna be a present for my 5 year old son

Looks like you've got some star trails

Having used both OSC and mono qhy183 CMOS cameras I'm happier with mono, especially as I mainly image from my back garden in a bortle 6 area. I've seen some absolutely amazing images lately produced by OSC cameras but I keep reminding myself most of these images are taken from very dark sites with alot better skies than the average UK weather allows.

Anything is better than nothing. Plus a very nice looking setup. Have you tried your JTD rig yet? I need to get one but they always seem to be out of stock or my funds are empty

Still alot better than my bortle 6 skies.

That's amazing for such a short integration time. You must have pretty dark skies. I tried this a few years ago with 30 minute subs and got nowhere near this.

Yep

Yes. I'm following this closely as I'm really hoping that they release one for the esprit 100

Best guess would be yes as it is optically matched and designed specifically for the scope
