Interview with Robin Glover – Author of Sharpcap

Hi Folks

 

Here’s a link to a fascinating interview with Robin Glover, talking to a New York interviewer about CMOS / CCD camera and exposure length

The bit I found interesting is a feature that’s now in Sharpcap Pro. It’s called Smart Histogram and it ‘calibrates’ the camera chip and the current background sky  brightness. It then calculates the optimum Gain/ Exposure settings for a particular imaging session

 

Mars – First pass on processing

Hi Folks

Here’s my first pass at processing some Mars image runs. I’ve been a bit too gentle on the processing this time round so I’ll go through again. The polar cap and some of the surface is starting to appear nicely. I need to get a better Barlow though.

The data set I’ve got to work with is 3 image runs totalling 15000 subs, taken with ZWO 170MC and Celestron 8SE with a x2 Barlow

Milky Way in Shropshire – Revised photo size

The photo after some editing. I think the Milky Way is better but the foreground has suffered. I need to learn about masking

Dave and I went to try out a new campsite in Shropshire that listed itself as a dark sky area. It didn’t  disappoint. It’s called Hamperley Campsite and it’s near Church Stretton

 

I edited the post as I’d forgotten to change the picture size. This was a single JPEG. I haven’t got round to editing it yet

Cheers

Observing on 14th August at Rosliston

Had a really good time at Rosliston last night. Everything seemed to go safely and smoothly (after we managed to get in!)

The gaps in the clouds made it worth going and Jupiter and Saturn kept us company for much of the time. The owls were hooting and planes going over head. The odd meteor made us happy too.

It was great be able to chat and chill together. Thanks to Heather for organising it, and to everybody who attended.

Invasion of the spiders

HI folks

 

As you saw last night, my 8″ SCT has been invaded by a couple of spiders which explains why I couldn’t see anything clearly. Andy asked last night how much effect that would have, given the size of the scope mirror

I think the flat in the second photo says it all. It was taken using en electroluminescent panel , which gave the even illumination as mentioned last night

Cheers

Ed
