Optolong light pollution filters

If you’ve read my other blog post about light pollution filters, you know I love them and they work really well especially with Deep sky images. Like all other products in the market, there are several brands that make the same product (similar), one of the companies that make these awesome light pollution filters is Optolong Recently, Optolong reached out to me and was asking about my experience with light pollution filters and they mentioned about one of their latest filters “L-Pro” filter, The description sounds good for the same, but you can’t tell unless you use it. I wasn’t in the market for new filters but asked them if they would like to send me their filters so I can test them out and yeah!!! they agreed and sent me 3 filters. CLS (City Light Suppression) UHC (Ultra High Contrast) L-Pro (L-Professional) CLS and UHC are really good for deep sky photography, as they provide less transmission of light pollutants and enhancing the contrast between the background sky and the nebula. CLS: Gives better results for objects that emit light in a broader spectrum, objects like reflection nebulae UHC: Gives better results for objects that emit light in a […]

A 5sec Exposure – East Cape Lighthouse

Often when you talk about astrophotography, first things that come to mind are Long Exposure and High ISO. For most of the time this is true but then there are times when you cannot use both at the same time and sometimes you just have to stick to short exposure times. Sometimes, the images produced with a short exposure will not have much detail of the sky, but if you are a dark site, it is sufficient enough to capture those details. I recently visited East Cape lighthouse, which is the easternmost point of New Zealand to capture the milky way rising next to the lighthouse. This was my first time so I did not know what to expect. These beautiful beams going across the sky looked so beautiful and I wanted to capture them with the milky way rising. As usual, I set up my camera to a 20sec exposure, ISO 6400, f/2.8 and not to be surprised but the lighthouse was overexposed and I did not capture any of those beams. A bit disappointed, I tried again with slow exposure and got better. Then I thought, the reason I am not capturing the beams is because, when on […]

LMC Processing – PixInsight Tutorial

I recently uploaded an image of LMC which is probably one of the best images i’ve processed so far. As i was processing the image, i decided to record the process, so i can upload that as a tutorial as in the past few people have asked about the processing. I used pixinsight for processing and photoshop for final touches. Keep a look around as i upload more videos. Here is a 11 part video series that shows the processing workflow.

M51 Processing – Photoshop

This is a short video of M51 processing. A friend of mine “Rahul Ramtekar” from Dhruva Skywatchers Association asked me to process this beautiful image of M51 galaxy shot from a Dobsonian telescope. I did not have DSS so this set of image was stacked in PixInsight, but any stacking software will do. The image was taken by Rahul Ramtekar of Dhruva Skywatchers Group – Nagpur, while observing through the 10″ Go-To Dob at Sillari, Pench with Pravin Jat. Canon EOS 60D + Skywatcher 10″ Synscan Dob Alt-Azimuth Tracked 20 images Stacked in DSS + Postprocessing in PS 29Sec, f/4.8, ISO 1600 19th March 2016, 4.20 AM, 21.3732455 N,78.7575318 E Telescope Credits: Observatory, Sillari Pench Tiger Reserve
