Some great images have been posted since my last visit here ☺ We are currently in Holland sailing, had 2 nights on a relatively dark island in the Veerse meer and captured a couple of milky way shots but forgot my camera lead so can't upload until I get home next week unless I sus out the wifi setting on my camera . Keep up the good work guys. Nige.

I think these are Noctilucent clouds ( high level cloud visible after sun down ), captured 14th June approximately 10pm in the NW sky with a couple of con trails. Please correct me if I'm wrong Canon 1300D ISO 400 Shutter speed 1-400 sec F 5.4 Focal length 21mm. Latitude 51 N A little polishing with Photoshop. I'm sure there will be some great images posted over the next couple of months and I look forward to them Nige.

Very interesting an very noticeable difference, when I use my 135mm lens at F3.2 I gather a fair bit more light than my 150p f5 reflector which surprised me . These are same modified camera same exposures both with CLS filter, the 135mm has been heavily cropped for this post but there is far more dust visible in the 135mm image. Nige.

Nice Bob, colours good and good detail, plenty of nebulosity. I think you might pick up more detail if you centre the Southern half rather than centre the complete nebula. I loose detail around the edge with my reflector so try to get the most detailed parts in the middle of the frame. Maybe mosaic 2 images, but still well done. An example, here's the same last year with my 150p 45s exposures. Nige.

I had posted my 41P image in the wrong thread so I'll post it here with last nights Comet Johnson image. Both 40 x 2 minute exposures stacked with DSS comet feature and processed with Startools. Comet 41P with 3 distant Galaxy's, March 2017 & Comet Johnson 30th May 2017. Nige.

Today I learnt that DSS has a comet stacking feature, so I stacked my 40x120s images from a couple of months ago and got a nice return. 500% better than before Comet 41P with 3 small DSO's. Nige. Edit: sorry wrong thread, should be in imaging WF

I had trouble with the unmodified 1200d camera, orange and pink being dominant but with the self modified 1200d and CLS filter the red responce is far better. I tried the modified without the CLS filter once but theres too much light polution washing out the images. Nige.

I have added an hour to the original NGC7000 image with a good result. 2 hours of 240s. Modified 1200d, Equinox 80ED. I don't know what the natural colour is but very little colour processing and this is the result. First is the 1 hour, 2nd is 2 hours. Nige.

Thank you all for your kind comments, my images are slowly improving and I'm loving the journey ☺ Nige.

Now I have turned off the camera NR everything is working just fine along with a very clear night and no dew Perfect. I dithered for the first time last night on a test of the Elephant trunk nebula. I wanted to see if its worth spending a few hours on the object with a small scope and DSLR. I have not spent much time on processing this image yet, It was easy to process I guess dithering did the job. I'm very supprised to see so much data in the image, well worth imaging even the dark dust is showing. This is 18x240s ISO800 with usual calibration frames. ED 80, EQ3 and modified 1200D. I also took a single sub on the Veil set to see that I should just about fit both East and West in the frame, so I'm looking forward to imaging them too. Cheers Nige.

I have never done dithering before, I have read a little about it. My setup is on camera guiding with PHD2, can I manually dither between exposures with PHD ? And then use Sigma Clipping combination method with DSS.

Thanks for the link Ken, I've had a read through. I'm going to try with it disabled to see if there's a noticeable difference. Nige.

Hey Bob. Thanks for that info. It turns out that my long exposure noise reduction was on auto so it would choose to reduce noise when it wanted to which would explain it starting halfway through a batch, disabling it has rectified the problem. Well done and cheers Nige.
