  1. Just testing the waters as I might dabble back to a reflector. But is anybody selling Sky-Watcher Explorer "P-DS" newts? I think I'm looking at the 200pds but most considered Cheers Ruzeen
  2. Hello from a fellow Northamptinian welcome to SGL
  3. A second hand Canon 450D that has had the IR filter and anti-aliasing filters removed. This is known as the Full-Spectrum (or naked sensor) modification. This enhances the camera's sensitivity to Hydrogen Alpha wavelengths greatly. Ideal for shooting emission nebulae, as well as making it a great candidate for Hydrogen Alpha filters. The camera has been modified by myself. It includes the camera body itself, body cap, battery, charger, plug, strap and I'll throw in an EOS-T2 T ring. Bit of cosmetic wear to the camera as to be expected. Note: removing the IR filters means that you'll need to add an astro-friendly IR filter back into the imaging train. This is usually achieved with filters like the Astronomik CLS-CCD filter (for example). Just check the description and make sure it has UV/IR cut. £150 + £11 Postage (Royal Mail Special Delivery)
  4. So I was fortunate enough to get one of the new Optolong L-eXtreme Filters for review, and even though there has been a heatwave this week I just had to give it a go. On the Monday I turned the equipment to the Eastern Veil Nebula NGC 6992. I first attempted 5 minute exposures, but I wasn't getting as much signal through as I was hoping. I ended up having to bump the exposures up to 10 minutes, ISO 800 with the L-eXtreme on the East Veil There was a definite green colour cast to the image. But after manually correcting this with a simple levels adjustment and some editing, the final result looked good for just 2 hours of data at 30 Celsius! I also turned this to the Pelican Nebula. I only managed to get 1.5hrs of data with this and the sensor was a whopping 33'C which damaged the data and induced some significant banding that I'm currently troubleshooting and trying to rectify. The data picked up though was nice even after an aggressive amount of noise reduction. The colours of the nebula are nice also. Very reminiscent of the Optolong L-eNhance filter (which makes sense). I just need more data and cooler data. The Pelican Nebula was shot with 5 minute sub exposures ISO800 on account of the temperature. If it was cooler I would've definitely used 10 minute exposures minimum. First impressions are promising. Very excited to try this more and to share my thoughts with you throughout my time with this filter. If you want further information then you can see my Optolong L-eXtreme First Impressions on YouTube If you want further reading then you can read the post on my website. Thanks everybody. Clear skies, keep looking up and keep them cameras clicking.
  5. Used Altair Lightwave flattener, 0.8x Works well with f5.5-f8 refractors. Bit of marring as expected on the nosecone but optics in A1 condition. Includes postage £50
  6. Hey there, I'm curious, how many people actually try any form of compositional techniques with their astrophotography? We have the rule of thirds and ratio and colour balance and weighting compositional elements in terrestrial photography. But how many people do this? I usually place my DSO in the centre of the frame, unless for say the Horsehead Nebula where it's usually good to have it spread through the frame. Or the M81/M82 where you share them on the side of the frame etc. So who else actually does any compositional elements or just places the DSO in the centre of the frame. All the best, Ruzeen
  7. SkyTech L-Pro Max Light Pollution Suppression Filter Used for about a year now and still in very good condition. really helped me out in my garden but now I've moved to tougher skies and need a slightly stronger filter. So it's time to pass this on to someone else. Filter is in very good condition with no scratches on it. Used extensively to great effect. Cardboard box slightly tatty but to be expected. Creates very nice pictures with good star colour retention and no halos. Horsehead is a HaRGB composite photo where the RGB was shot with this filter. 2" fitting (M48). Will come with outside box, interior box and of course the filter. £100 + £8 P&P (Royal Mail Special Delivery)
  8. Supply is drying up and it's hard to get stock in to the UK it seems. Looking at most websites a lot of stuff is on back-order so Wanted ads are going to crop up a lot! Now's the time to sell certainly. I reckon the price of secondhand gear might creep up as well due to the demand.
  9. Oh well yes I would agree that your larger telescope would get more finer detail and resolution. I guess in this case then I was just talking in general about under/over sampling as mentioned by the CCD Calculator. In terms of resolution and what sort of detail it can pull out, yes larger aperture is always better. To a limit I guess due to the atmosphere. I would really enjoy using a larger telescope sometime in order to compare the difference in resolution, that's for sure.
  10. As fun and interesting as it is, I think that's going far too deep than I want to I say that, but it's in my mind now and I've got that sort of head where I want to go and research it now. Can you point me anywhere to learn more?
  11. Definitely interested in this. Missed it last year, think I'll start accruing the necessary camping gear and funds and cross about everything finger and toe going that the weather and Rhona situation is all good
